[Not Applicable]
The invention relates to gaming machines and display devices.
In the past gaming machines included a number of mechanical reels which were spring loaded and released to spin by the pulling of a handle. The reels randomly stopped to display their symbols and define one or more outcomes.
Today, some gaming machines are electromechanical in nature and have mechanical reels driven by stepper motors to rotate and stop in a controlled manner to display outcomes derived from symbol combinations displayed on reel strips that are located on the periphery of the mechanical reels. Because of the stepper motors, these types of games are often referred to stepper games. A drawback to current stepper games is that the symbols on the reel strips are fixed. That is, the symbols are printed on the reel strips and hence they can only be changed by changing the printed reel strips.
Other current gaming machines employ video displays in order to display virtual reels to a player of a game. However, such gaming machines do not have the aesthetics and player appeal of electromechanical gaming machines with the physical, spinning reels.

The display may additionally be used to impart visual effects at positions where there is a symbol This gaming machine allows dynamic reel strips where the symbols of the variable displaying position can be changed (for example by being selected from a set of symbols) while retaining at least some of the game play experience of a mechanical reel machine.
A gaming machine comprises several functional components. At the broadest level, the components are a player interface 50 and a game controller 60 as illustrated in
Components of the player interface may vary from embodiment to embodiment but will typically include a credit mechanism 52 to enable a player to input credits and receive payouts, one or more displays 54 and a game play mechanism 56 that enables a player to input game play instructions. The credit mechanism 52 may be, for example, a bill acceptor which is configured to receive, validate and credit a cash amount to a credit meter for the game, as is known in the art. In certain embodiments at least one display of the gaming machine is provided by one or more display devices in the form of reel assemblies which include a mechanical reel and a display as described in further detail below.
The game controller 60 is in data communication with the player interface and typically includes a processor 62 that processes the game play instructions in accordance with game play rules and outputs game play outcome data to the display 54. Typically, the game play instructions are stored as program code in a memory 64 but can also be hardwired. Herein the term “processor” is used to refer generically to any device that can process game play instructions in accordance with game play rules and may include: a microprocessor, microcontroller, programmable logic device or other computational device, a general purpose computer (e.g. a PC) or a server.
An example of the external physical form of a gaming machine 10 is illustrated in
A top box 26 may carry artwork 28, including for example pay tables and details of bonus awards and other information or images relating to the game. Further artwork and/or information may be provided on a front panel 29 of the console 12. A coin tray 30 is mounted beneath the front panel 29 for dispensing cash payouts from the gaming machine 10.
The top box 26 may also include an electronic display, for example a video display unit, particularly a cathode ray tube screen device. Alternatively, the top box display 26 may be a liquid crystal display, plasma screen, or any other suitable video display unit.
The gaming machine 100 includes a game controller 101 having a processor 102. Instructions and data to control operation of the processor 102 are stored in a memory 103, which is in data communication with the processor 102. Typically, the gaming machine 100 will include both volatile and non-volatile memory and more than one of each type of memory, with such memories being collectively represented by the memory 103.
The gaming machine has hardware meters 104 for purposes including ensuring regulatory compliance and monitoring player credit, an input/output (I/O) interface 105 for communicating with peripheral devices of the gaming machine 100. The input/output interface 105 and/or the peripheral devices may be intelligent devices with their own memory for storing associated instructions and data for use with the input/output interface or the peripheral devices. A random number generator module 113 generates random numbers for use by the processor 102. Persons skilled in the art will appreciate that the reference to random numbers includes pseudo-random numbers.
In the example shown in
In addition, the gaming machine 100 may include a communications interface, for example a network card 112. The network card 112 may, for example, send status information, accounting information or other information to a central controller, server or database and receive data or commands from the central controller, server or database.
As indicated above, certain embodiments employ display devices that are reel assemblies which combine a mechanical reel having a reel strip with a small electronic display arranged to display content at a variable displaying position of the mechanical reel, in one typical example by displaying a symbol through a window in the periphery that defines the variable displaying position. The mechanical reels are preferably driven by stepper motors which are well known in the art. The stepper motor allows the mechanical reel to be moved through a series of incrementally-spaced positions, e.g. 22 stops, and to be stopped at a desired position. In this way, the mechanical reel can be stopped at any one of a plurality of stop positions as determined by the processor 102. In the prior art, each of these stop positions corresponds to a symbol position. That is, a reel strip of printed symbols is affixed to the outer periphery of the reel. In most stepper machines of the prior art, a processor in combination with a random mechanism, such as a random number generator, randomly selects stop positions for each of plurality of reels (for example 3 to 5 reels) and the result is determined by the processor and random number generator based on these stopping positions. A variation on such a system is described in U.S. Pat. No. 4,448,419 to Telnaes where there is a virtual expansion of a reel by mapping at least some actual physical stop positions to more than one possible outcome thereby changing the odds of particular outcomes.
Referring to
As shown in the drawings, within the periphery of the reel 705 is an arrangement of electronic video displays 760A-C supported and positioned to register with the window 755 when the window stops within the viewing window 16 of the machine 10. Thus, in certain embodiments, where the display 760A-C displays content in the form of a symbol, the variable displaying position or provided by window 755C and the other printed symbol positions 750 provide a set of symbol positions for the reel. Typically there will be 20 to 22 different symbol positions or “stops” on the reel. By providing the display 760A-C the effective number of symbols (or blanks) which can be presented during a game is not constrained by the number of reel stops. For example, where a display 760A-C is controlled to display an additional 20 symbols at one window 755, the reel strip has effectively 20 additional stop positions.
Typically at least one symbol position, such as, for example, 3 to 5 symbol positions will be viewable for each reel assembly 700 through the viewing window 16 shown in
Each reel assembly 700 includes one or more peripherally arranged video displays 760A-C disposed, when viewed from a position of a person viewing the reel strip 750 through the viewing window 16, behind the reel strip 750 as depicted in
The displays 760A-C may also be activated by the processor to flash or generate color during the rotation of the reel to enhance the viewing entertainment value. Flashing may be timed with the rotation of the reel 750 and the presentation of the symbols 749 or windows 755 over the displays 760A-C during rotation or may be timed differently. The video displays 760A-C or one or some of them may continuously or intermittently provide a color background to the symbols 749 or blanks of the reel strip 750. Displays 760A-C may also be controlled by the processor to flash or assume a color or other condition to highlight the symbols of winning combinations.
With reference to
A person skilled in the art will appreciate that in a typical gaming machine there will be a plurality of reel assemblies 700 arranged next to one another in order to provide game outcomes. For example, a typical gaming machine will contain 3 to 5 reel assemblies 700. A person skilled in the art will appreciate that there are a number of variations that can be achieved. For example, there may be more than one window 755 on each reel strip 750. For example, there could be from one window 755 to several windows with the remainder of the symbols printed on the reel strip 750 to a window 755 at every symbol position on the reel strip 750. That is, the reel strip 750 may not include any symbols printed thereon and instead rely on the video displays 760A-C to display all symbols or other content to the player and to display images timed with the rotation of the reels to provide the desired visual affect of symbols rotating past the viewing window 16. The reel strip 750 may be configured to have different patterns of windows 755 and pre-printed symbols so that the reel 705 when stopped may present from none, one, two or three adjacent windows 755 over the video displays 760A-C. Thus, in this example, it will be possible to control the gaming machine so that sometimes one, sometimes two, and sometimes three windows 755 in the display window 16.
A number of variations are possible to the above embodiment. For example, while some of the aesthetics of a mechanical reel as provided by allowing several symbols to be seen on the reel surface during the spin. It is possible that the reel periphery may be composed entirely of windows such that all symbols become dynamic, in this case, the rotating mechanical reel periphery provides the aesthetics of rotation. Further, while most reels show three symbols in the display window at a time, this could be adjusted to another number such as two or four symbols. When a printed symbol is over a display, the display can act just as a white backlight, although other colors could be used for bonusing or special effects.
It is also possible to use other display technology. For example the video displays 760A-C may be embodied as reflectors (mirrors or prisms) with a projector focused to projects video content to the reflectors for reflection of the content through the windows 755. In a projector embodiment, some of a spin effect can be simulated by the projector. Where the projector is disposed to one side of the reel assemblies 700, the reel 705 may include spokes 800 positioned to interrupt the projected light to simulate the “flicker” of the spinning reel symbols.
It will be appreciated for the foregoing that the present invention provides a number of advantages including that some symbols of the game can be animated, more than one symbol can be displayed at any variable displaying position thereby changing the available game outcomes, symbols can be flashed in unison with the spinning reels to enhance the spinning sensation of the mechanical reel; and games or game themes can be changed through replacing/downloading new games or themes either dynamically via server based gaming or manually in order to modify the gaming machines. Further, as the device is mounted directly to the support the connections to the displays do not at involve complex wiring.
