2. Description of the Related Art
Bingo and bingo-like games are well-known games of chance in which each player's chances of winning depend on randomly selected numbers. Bingo conventionally involves a caller who draws the randomly selected numbers, often printed on balls, and calls out the drawn numbers to a group of players. Any called number may match entries contained on pre-printed patterned arrays, commonly called “faces,” displayed on bingo cards sold to players. The most popular face is a 5×5 array in which all but the center entry is a number. The letters B-I-N-G-O are displayed above the array, such that each letter is aligned with a vertical column of the numeric entries. A one or two-digit number generally from 1 to 99 appears in every array entry on the bingo card except the center entry, which is designated as a “free” play entry. The randomly generated numbers are obtained from a central source. The central source may be, for example, a set of bingo balls from which random numbers are drawn. The number of balls corresponds to the range of alphanumeric combinations available on the bingo cards. Namely, each ball includes one of the letters B-I-N-G-O and one number from the available range of numbers. From an air-ball machine or a box, a caller randomly selects balls sequentially one at a time and announces the letter and number appearing on each of the balls. Players having bingo card faces with letter/number combinations matching the balls called, mark the corresponding matches using an ink dauber. In one standard version, the word “bingo” is called out by a player when he/she discovers that five numbers have been daubed in a straight line either vertically, horizontally or diagonally. Each player may play multiple bingo cards given that playing more cards increases the player's chances of winning a given game.
A variation of the traditional bingo game utilizes electronic bingo card displays rather than the traditional printed paper bingo cards. In these electronic bingo-type games, each bingo card is represented by a data structure specifying the numeric entries in the bingo card face arrays. This type of electronic bingo may be played using player stations connected via a communications network to a centralized game controller. The game controller stores the bingo card representations and electronically distributes the bingo card representations to the player stations. The player stations display the bingo card representations and include user controls that enable the players to select matching numbers announced during the game. Electronic bingo games may be played at a much faster pace than is practical with traditional paper bingo. Furthermore, electronic bingo dispenses with the cumbersome and wasteful use of paper bingo cards and enables a centralized controller to control a bingo game played by players at player stations distributed across a number of different bingo establishments.
While providing many advantages, it may be desirable for electronically displayed bingo to retain the basic characteristics of a bingo-type game. Prominent among such traditional characteristics is that the game be played with predefined cards or card representations which the players match against a randomly generated master game indicia sequence. Prior art electronic bingo designs generally employ design features that are technically convenient but do not adequately reproduce or simulate the conventional bingo game experience and therefore have not gained widespread popularity. Notable among the prior art designs in this area disclosed in U.S. patents are:
Richardson, in U.S. Pat. Nos. 5,007,649; 5,043,887; 5,054,787; and 5,072,381 teaches an electronic bingo system in which a plurality of arrays of indicia, each corresponding to a separately displayable face, are downloaded from a central computer into a memory portion of a player's electronic game board. A floor walker's validation terminal is used to validate a winning combination by means including receiving a unique game-specific code (which may conveniently be a serialized number known as a “permutation number” associated with a particular algorithm for generating the set of all permutations of allowable indicia) from the allegedly winning game board. Richardson's game board comprises a card display and a keypad. The use of the keypad to enter called numbers is not simulative of the physical marking of paper cards. Moreover, Richardson's game board displays only a single face and thereby fails to facilitate N-on play.
Itkis, in U.S. Pat. No. 5,478,084, teaches a mechanical bingo machine that displays multiple playable faces at one time (e.g., a 6-on card) and that uses a permanent magnet to move suspended ferromagnetic particles from a hidden side of a display board to a visible side in order to make a white-to-black transition, simulative of an ink dauber being used, to mark called numbers.
Frain, in U.S. Pat. No. 5,230,514, teaches an electronic game board comprising 2-on to 18-on card displays and a plurality of player input means, including means to select a special game. Frain provides no way of changing the display on any one of the boards. A player who wants a different set of numbers is required to turn her board in for another one.
Matsumoto et al., in U.S. Pat. No. 5,755,619, show a casino bingo apparatus in which each player uses a touch-screen terminal hard-wired to a central unit. The central unit keeps score and uses conventional bingo balls to generate called numbers. The required wiring makes installation of Matsumoto's expensive and essentially requires a dedicated facility.
It can therefore be appreciated that a need exists for a method, system, and computer program product for displaying bingo face representations in a manner overcoming the foregoing problems encountered in the prior art. The present invention addresses this and other needs unresolved by the prior art.
A system, method and computer-readable medium for implementing gaming systems and devices using portable e-ink bingo display devices are disclosed herein. In one embodiment, an electronic game device includes a display controller adapted for generating a game face and a display assembly that displays the generated game face. The display assembly includes an electronic ink display sheet on which the generated game face is displayed, and a dauber interface that converts dauber input signals to electronic signals received by the display controller to adjust the display of the game face on the electronic ink display.
The above as well as additional objects, features, and advantages of the present invention will become apparent in the following detailed written description.
The novel features believed characteristic of the invention are set forth in the appended claims. The invention itself however, as well as a preferred mode of use, further objects and advantages thereof, will best be understood by reference to the following detailed description of an illustrative embodiment when read in conjunction with the accompanying drawings, wherein:
The present invention is described in a preferred embodiment in the following description with reference to the figures. While this invention is described in terms of the best mode for achieving this invention's objectives, it will be appreciated by those skilled in the art that variations may be accomplished in view of these teachings without deviating from the spirit or scope of the present invention. Furthermore, when used and unless otherwise stated, terms such as “horizontal,” “vertical,” “upper,” “lower,” “front,” “back,” “over,” and “under,” and similar position related terms are not to be construed as limiting the invention to a particular orientation. Instead, such terms are to be construed only on a relative basis with respect to the accompanying depicted embodiments.
The present invention is generally directed to electronic bingo game devices, assemblies, and systems that dispense with the need for the time and material expenditures as well as the game usage inflexibility associated with conventional paper card bingo systems. A portable electronic display device employing an electronic ink display overcomes many problems associated with paper bingo cards while also addressing problems associated with conventional electronic bingo displays.
It will be recognized by those skilled in the gaming arts that the game traditionally known as bingo is only one of a number of bingo-like games of chance. The present invention applies to the general category of bingo-like games in which a player views a proximally displayed pattern of indicia that comprises a subset of all such playable indicia, monitors a randomly or otherwise selected sequence of indicia from the set of all possible indicia supplied by a common source or controller, marks those indicia from selected sequence that appear on his/her array(s), and receives a prize if a correctly marked subset of the randomly selected sequence corresponds to a characteristic winning pattern of the indicia disposed on his/her local display. Such bingo-like games are further characterized in that each player submits payment for each proximally displayable array of indicia prior to the sequence of indicia being selected.
The present invention is further directed to electronic equipment for playing a bingo-like game in a manner that closely simulates the conventional game of bingo played with paper cards while also enabling a more efficient bingo game experience to accommodate today's players who are increasingly accustomed to more fast-paced entertainment. The present invention is further directed to a portable electronic bingo display device that may include a tracking mechanism to prevent players from missing a winning pattern when playing multiple cards and multiple bingo-like game types. In this manner, the invention aids novice players and players with physical disabilities who otherwise may be at a competitive disadvantage in playing conventional paper card bingo.
With reference now to the figures, wherein like reference numerals refer to like and corresponding parts throughout, and in particular with reference to
In a preferred embodiment, and as explained in further detail below, the electronic bingo display devices comprise a portable electronic paper or electronic ink (e-ink) display device. The e-ink design enables the display devices to closely simulate the feel and function of traditional paper bingo cards while incorporating many of the advantages derived from electronically coupled, controlled, and networked display devices.
The e-ink display devices within gaming system 10 include e-ink display cards 8a-8n, 11a-11n, and 24a-24n that enable players to co-participate in centrally controlled bingo games using different gaming interfaces at possibly difference game sites. In this manner, players at different gaming facilities may be grouped together for a given bingo game administered by master game controller 4. Grouping together players from different gaming facilities for commonly played bingo games enables different bingo games to be played rapidly and minimizes the time that players must wait to receive bingo game results.
Master game controller 4 includes electronic and program modules for rapidly grouping players and/or game type/play requests and starts games sequentially and concurrently so that multiple games may be in play at any given time. That is, once a first group of players and/or game play requests have been received by gaming system 10, the system proceeds via master controller 4 to commence and administer a bingo game for the first group of players or game play request while also grouping players or game play requests for other bingo games without waiting for the ongoing game(s) to terminate. In this manner, gaming system 10 may concurrently administer numerous bingo games displayed by many thousands of electronic bingo displays at various remote locations throughout the gaming system.
Regardless of the rapid, automated game control and display facilitated by gaming system 10, the underlying game preferably adheres to the basic game principles characteristic of a standard bingo game. Such basic bingo game principles include assigning each player one or more bingo cards or bingo card representations, daubing or otherwise marking all bingo cards in play for matches with a randomly generated sequence of typically alphanumeric indicia, and determining the winning card(s) as the first card(s) in the game to match the sequence of designations to produce the pre-specified game winning pattern.
While not expressly depicted in
The sequence of randomized indicia may be, for example, a ball draw in which balls or representations of balls each having a number and letter are randomly selected sequentially. It will be appreciated that this type of ball draw or other sequence of randomized indicia may be produced by a random number generator module or any other suitable module or device within master game controller 4, and not necessarily a physical ball draw device.
Gaming system 10 further includes network connectivity provided by a wide area network (WAN) 15 to a remote gaming site 27 and remote nodes such as node 19. Node 19 may be an administrative node having authorized access to control features and mechanisms within master game controller 4 and other control nodes within the depicted gaming system 10. Remote gaming site 27 includes a local game controller 22 communicatively coupled to multiple e-ink bingo card displays 24a-24n. While not expressly depicted in
In addition to remotely situated e-ink bingo display devices within gaming site 27, gaming system 10 includes multiple e-ink bingo display devices 8a-8n and 11a-11n situated locally within gaming site 25. Display devices 8a-8n and 11a-11n are preferably lightweight and readily portable devices that may be hand-carried by players to desired locations and game ports within gaming site 25. As depicted and explained in further detail below, the display devices fundamentally include an electronic display surface on which bingo card representations may be displayed. In accordance with the depicted embodiment, the display devices utilize an e-ink display assembly (depicted in
In one aspect, the portable bingo display system of the present invention encompasses wireless connectivity that enables the display devices to be freely moved prior to and during a given bingo game session in a manner similar to the familiar mobility of paper bingo cards. To this end, and as shown in
In another aspect, the portable bingo display system may alternately employ portable bingo display devices that may be coupled to master game controller 4 via a player station apparatus such as display table 2. Namely, display table 2 includes multiple display ports 18a-18n that provide communicative connectivity with master game controller 4 and optional power supply from a DC power source 6 for display devices 8a-8n.
The particular configuration of devices shown in
In the depicted embodiment, bingo card representations are displayable on display assembly 35 housed within a body member 45. Prior art electronic game displays are subject to failure in service when the board is exposed to liquids such as an accidentally spilled beverage during the course of play. Body member 45 therefore preferably comprises a sealed, liquid-tight housing preferable having no outer exposed metallic electrical connections extending to its surface. Integral to body member 45 or as a separate structural feature, a cover layer 38 provides a protective layer above and adjacent the display surface of display assembly 35. Cover layer 38 is a substantially transparent sheet member made of a resilient polymer or other material suitable to provide protection to the surface of display assembly 35 from exposure to liquids and direct mechanical contact.
Bingo players often play multiple faces simultaneously in an arrangement commonly called “N-on play,” where N is the number of faces being played. Bingo operators therefore often sell cards having multiple faces printed thereon.
As explained in further detail below with reference to
Whether used as a standalone unit or incorporated within a portable body, display assembly 35 is readily portable and can be readily carried by a player and used anywhere a conventional paper bingo card may be used. The portability of the device may limit continuous accessibility to an AC electrical power supply, and require that the device operate using an integral battery or other portable power supply. The device is therefore preferably designed for minimal power supply requirements in order to maximize reliable playing time. Many electronic display technologies such as LED, LCD, CRT or plasma panels are available for portable bingo game displays. In a preferred embodiment, the face fields within display assembly 35 are e-ink displays which have a substantially lower power supply requirement. As explained below with reference to
Another feature of a preferred embodiment is a sensing mechanism for marking an e-ink display in a manner similar to the use of conventional ink daubers in marking paper bingo cards. In one embodiment, the sensing mechanism comprises a marking means, or “dauber,” that simulates an ink dauber that is commonly used when playing bingo with paper cards.
For the embodiment in which dauber 41 is magnetized, a Hall effect sensor (not depicted) is disposed within overlay sheet 38 or in a substrate layer (depicted in
With reference to
The depicted embodiment further includes features for addressing problems that may arise when players simultaneously play multiple types of bingo games as defined by different winning patterns. As known in the art, the standard winning patterns of aligning five numbers on a card horizontally, vertically, or diagonally have been supplemented by a number of other, often more complex, winning patterns. Exemplary of the additional, more complex winning patterns are “Four Corners” where winning numbers are found in every corner of the array, “Small Diamond” where four winning numbers are found encircling one cell in the array; and “Large Diamond” where winning numbers are aligned diagonally encircling a small diamond. In addition, the prevalent use of wild card numbers adds to the complexity of tracking winning patterns particularly when playing multiple faces.
Wild card numbers and the winning patterns may change for each bingo game and players must be aware of these changes and apply the corresponding rules correctly for each called number. The complexity of tracking several winning patterns for each game combined with the large number of cards played, naturally increases the chances that a player will miss noticing and marking matches between a called number and a matching pattern entry.
The e-ink display device of the present invention includes features that address these problems by facilitating a player's ability to track one or more particular bingo patterns among several variations that may be in play simultaneously. Namely, and referring again to
As an aid for assisting a player to determine whether a winning pattern has been achieved at any point during a game, bingo card 40 includes a game control button 46 which, when daubed or otherwise selected, provides a winning pattern display prompt to a local or external display controller. In one embodiment, the winning pattern prompt results in one or more possible winning patterns corresponding to marked cells being persistently or temporarily displayed in a manner highlighting a winning pattern that has been achieved. For example, if the game being played on bingo card 40 is “Four Corners” and the correct four corner cells containing the numbers 10, 63, 95, and 12 have been daubed, the display prompt signal resulting from selection of game control button 46 may instruct the receiving display controller to provide a visual highlight, such as a color-coded or pattern-coded indicium to each of the four corners to assist in apprising the player that a winning pattern has been achieved.
As further illustrated in
The unmark control button 52 provides a convenient means by which a player can remove both the visual indication of and underlying game controller recordation of an inadvertently or otherwise incorrectly daubed cell. If, for example, the caller calls B11, which matches a cell on bingo card 40, and the player responds by inadvertently daubing an adjacent cell B2, the player may correct the mistake by first daubing the unmark button 52 to set the display controller in a “daubing correction” mode and then daubing the incorrectly marked cell to remove the visual and underlying data recordation.
The display, and particularly the dynamically alterable numeric indicia are displayed by bingo card 40 using e-ink, sometimes referred to as electronic paper or E-paper technology. E-ink is an emerging display technology developed to overcome some of the limitations of conventional electronic display devices such as LCD and plasma screens. E-ink displays closely simulate the appearance of ink on paper. In contrast to conventional flat panel displays which use a backlight to illuminate its pixels, an e-ink display reflects ambient light in a manner substantially identical to ordinary paper. E-ink displays are also capable of holding text and images indefinitely without requiring processing cycles or otherwise consuming electricity until the image is changed.
For example, the backlighting utilized by conventional electronic displays strains human eyes and is subject to interference and negation by ambient lighting conditions. E-ink is applicable to sheet substrates to form E-paper which reflects ambient light in substantially the same manner as true paper. E-ink displays lightweight, durable, and highly flexible compared to other display technologies and are easier to read at an angle than flat screen monitors.
Using e-ink technology enables bingo display devices such as bingo card 40 to more closely resemble and functionally replicate paper bingo cards which may be a significant actor in determining whether bingo games played with the E-ink displays comply with federal, state, and local laws and regulations relating to gaming classifications. By providing a user-held bingo display forum and including daubing means and control button interactivity, bingo card 40 enables preservation of legally significant aspects of traditional bingo games.
Referring to
To form display layer 42, the e-ink is deposited onto a thin film that is laminated to a layer of circuitry (not depicted) that forms a pattern of pixels that are controlled by a display controller. The microcapsules are suspended in a liquid carrier medium allowing them to be printed or otherwise fluidly deposited onto the film using existing screen printing processes.
Microcapsules utilized in e-ink applications are characterized in that they form a sealed chamber containing negatively and/or positively polarized particles suspended in a fluid. Several color scheme variations have been developed for e-ink applications. In one application the microcapsules contain both negatively charged white particles and positively charged black particles. Responsive to a region of the bottom electrode applying a negative electric field and an opposing region of the top electrode applying a positive electric field, the white particles move to the top and black particles move to the bottom of the microcapsules between the opposing electrode regions where they become visible to the user. This makes the corresponding surface region appear white. By reversing the electrode polarity, the black particles move to the top of the microcapsules, making the surface region appear dark.
In depicted embodiment, microcapsule 55, representative of the other microcapsules, forms a sealed unit containing a dark (e.g. dark blue) ink in which tens, hundreds, or thousands of light colored (e.g. white) pigmented particles 67 are immersed. While the exemplary microcapsules are described as having white particles and blue ink, numerous alternate ink and particles colors, such as for multicolor displays, may be utilized without departing from the spirit or scope of the present invention. Depending on the electrical polarity across electrodes 49, the particles 67 will either be driven to the top or bottom of each respective microcapsule. When driven to the top, the white pigmented particles cause the respective microcapsules to appear white. When an opposite polarity is applied across electrodes 49, the particles are driven to the bottom so that the corresponding microcapsules assume the color of the dark ink. Patterns of white and dark symbols can then be created in accordance with the electric fields applied to various regions of the display plane 42 to form the letters, numbers, etc. included in the surface display of bingo card 40.
It should be noted that the cross-section view in
Communications interface 78 includes transceiver and signal processing modules that enable wireless and/or wired communications between the display controller 75 within e-ink display device 30 and its respective local controller such as local controller 22, table controller 16, etc., and/or master controller 4. E-ink display device 30 further comprises a user input/output (I/O) interface 77 which enables player participation in the bingo-like games provided through gaming system 10, and dynamically displays intermediate and final game results. User I/O interface 77 preferably includes player controls such as the aforementioned dauber 41 and touch screen or magnetic proximity sensor display arrangement described above with reference to
User I/O interface 77 also preferably includes a card reader, bar code reader, keypad, or other user input mechanism that enables players to input player-specific and/or payment account-specific data for facilitating confirmation and/or receipt of wager amounts and dispensing of winning amounts as well as for player card authorization and authentication. For example, user I/O interface 77 may include a magnetic card reader or biometric reader (not depicted) adapted to read player-specific information from a player account card or the player him or herself. For the embodiment in which user I/O interface 77 is adapted to receive player and/or payment account identity information, such information may be stored in memory 72 as player/account information 76.
Failure of an electronic gaming device during play may result in extremely negative reactions from players who may feel cheated. Therefore, and as previously explained with reference to
As further depicted in
Referring to
The display identification data is further used by the game controller to initialize the display device as being a member of a specified bingo game session. As part of a typical initialization, the game controller may issue a “start” or “reset” message to the display device. The controller may then generate one or more of bingo indicia patterns, each corresponding to a separately playable face and downloaded to the display device. As is well known in the art, any combination of generated bingo array indicia patterns must satisfy the condition that no two faces used in the same game have the same array indicia pattern. Once the bingo indicia patterns have been downloaded to the display device and other participating display devices, the game controller may remain substantially idle through the remaining portion of the game session. In an alternate embodiment, and as explained with reference to the following steps, the game controller may perform other game time functions such as random number generation for the indicium calls, wager and payout accounting, etc.
Proceeding as illustrated at step 86, the e-ink display device receives and displays one or more bingo card face indicia patterns sent from one of the game controllers. The indicia patterns generated and sent by the game controller may be the well-known patterns of integers between 1 and 99 entered into each of the array positions in a bingo card representation. In one embodiment, the game controller may generate and send the card face patterns in response to validated requests for one or more card faces delivered by the display device to the controller as part of registration/initialization step 84. In a preferred embodiment, the received bingo card faces are displayed by the display device using an e-ink display assembly as described herein with reference to
After initialization and pattern display setting, the bingo game commences with the display device along with other participating devices receiving randomly determined game series indicia (step 90). The game series indicia are typically numbers that are pseudo-randomly generated or otherwise determined by master controller 4 which may also determine, after each call, whether any of the bingo indicia array patterns played by the display device and other participating devices have achieved, or are actually displaying in accordance with user marking, a winning arrangement.
In one embodiment, the game controller may run a pseudo-random number generator routine to generate the sequential indicium calls received by the display device during a bingo game. In a desirable alternative embodiment, the system of the invention such as gaming system 10 may utilize conventional, non-autonomic means of generating called indicia and verifying winning patterns such as by using a human caller and floor walker.
Responsive to or following receipt of each indicium from a game controller or game caller, the display device may or may not receive an indication of a player response, such as when the player daubs a matching indicium entry displayed on the display device. If, following receipt of the indicium from the game controller, a player “daubing” response is detected or otherwise received such as via user I/O interface 77, the display device records, displays, and sends the daubing response to the master game controller (steps 92 and 98).
If, as illustrated at steps 92 and 94, no player daubing response is received following receipt of the indicium, the display device may or may not generate a prompt or backup response depending on whether an automatic response check backup is enabled. Responsive to a backup response check not being enabled, the game processing for the presently received game indicium ends and the process returns to receiving the next sequential indicium at step 90. In response to an automated backup response check being enabled and finding a match (i.e. the player missed a matching pattern entry), the display device records, displays, and sends the appropriate “daubing” response to the master controller as depicted at steps 94, 96, and 98.
As is well known, the play of a game of bingo continues until a player covers or marks a winning pattern of indicia (step 100) and calls bingo or signals bingo using a display mounted control button (step 104). At this point, play stops and the player who called bingo submits his or her winning face to a representative of the game operator for validation of the claimed win. Alternatively, and as shown at step 109 the winning pattern signal may be electronically submitted via the display device and received by the master game controller which verifies whether a winning pattern has been achieved. As depicted in the sequence of steps 100, 102, and 110, if a winning pattern has not been detected or affirmed by the player such as by actuating a display control button such as control button 48, display device, or game controller, the game may be otherwise terminated such as by another player/display device achieving a winning pattern. Otherwise, if a winning pattern has not been achieved by the display device or another device or player, the game continues with the next received game pattern indicium at step 90.
If a winning pattern has been technically achieved and is recognized by the player, the game ends as shown at steps 104 and 110. If a winning pattern is not recognized or otherwise not responded to, such as by a failure to daub the winning pattern entry, the system may detect and send an appropriate win signal to the master controller if an automated response check is enabled (steps 106, 108). Otherwise, as shown at steps 106 and 90 the game continues with the next received indicium.
The disclosed methods may be readily implemented in software using object or object-oriented software development environments that provide portable source code that can be used on a variety of computer or workstation hardware platforms. In this instance, the methods and systems of the invention can be implemented as a routine embedded on a personal computer such as a Java or CGI script, as a resource residing on a server or graphics workstation, as a routine embedded in a dedicated source code editor management system, or the like.
While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention. These alternate implementations all fall within the scope of the invention.
