This invention relates to physical puzzles having separate colored segments that can form a particular color pattern.
There has long been a market for puzzles and games that are aimed at adults rather than young children. One area of the adult gaming market is 3D-puzzles. This is where the user has to solve a puzzle in 3 dimensions. The most famous of these puzzles is the Rubik's cube. This puzzle was invented in 1974 by Erno Rubik and challenges the user to align the segments of the cube so that each side is a homogenous color. This puzzle became a worldwide phenomenon in the 1980s and 100 million pieces were sold in the period 1980-82. Many other similar puzzles were introduced to cash-in on this market.
An example of a more recent puzzle is the 3D-pyramid. Like the Rubik's cube the aim of this puzzle is to arrange the segments in three dimensions so that all sides are a different homogeneous color. Unlike the Rubik's cube each segment is detachable and coupled to the neighboring segments via plastic slip connectors.
These puzzles can be fun for the user but if the desired end state cannot be reached, and there is no prospect of doing this, then interest is often lost and the puzzle is discarded. Conversely, if the puzzle is too easy then the user solves the puzzle and it is also discarded. Both of these scenarios can be assigned to the fact that the segments have fixed colors giving the puzzle only one difficulty level.
It is an object of the present invention to provide a physical puzzle made of colored segments wherein the color of a segment can easily be changed.
This object is achieved by a game according to a game comprising:
Preferably, the light module comprises solid-state light sources, such as light emitting diodes. Integration of diodes in the puzzle makes it possible that the segments of the puzzle can have changing colors. By controlling these colors by a processor, it is possible to give the user the possibility of asking for a hint or setting a certain difficulty level. Furthermore, it gives a puzzle designer an added degree of freedom and allows for the generation of new features.
In an embodiment, the segments can be rearranged in a certain order so as to solve a puzzle. The puzzle can for example be a 3-dimensional puzzle such as the Rubik's cube wherein the puzzle comprises 26 separate segments and a core mechanism arranged to hold together the segments.
The light module in the segments may comprise at least two light emitting diodes arranged to radiate light of different colors. In this way the segments can get different colors using a relatively simple electronic circuit.
In an embodiment, each of the segments comprises a battery. Alternatively, only one battery may be present which is arranged to supply power to all segments. Integration of power supply into the game is preferable since it obviates external power connections.
The battery may be a rechargeable battery. In this way, the game does not need to be opened up in order to put in new batteries.
In an embodiment, each of the segments comprises a transceiver arranged to transmit to and receive signals from other segments. This allows segments to communicate with other segments without the need for hard-wired connections or slip contacts. The transceivers may comprise a capacitive coupler. These couplers can be arranged inside the housing of the segments leaving the outside surface of the segments intact, thereby preventing damaging of the couplers, which is preferable with a puzzle wherein segments graze such as the Rubik cube.
In an embodiment, each segment comprises a processor arranged to control at least one light module inside said segment. Placing a processor inside each segment makes communication with a central processor unnecessary. Instead, communication with neighboring segments may be needed. This can be arranged by using for example the capacitive couplers described above.
In an embodiment, the processor comprises a memory arranged to store game rules. This comprises string “boundary conditions” of a game. For example, a Rubik's cube cannot be randomly mixed, which requires a severe set of rules. By storing rules, the processor possesses knowledge on how the user needs to solve the puzzle. So it can give hints to the user by for example, blinking certain lights.
The processor may be arranged to receive an input signal indicative of a reset of the game, a request for a hint, a trigger to start another game and/or a command for turning off the game.
In an embodiment, the processor is arranged to be programmed by a user by way of an external programming tool. This external tool may be used to program the processor giving the game a new set of rules resulting in a new puzzle with the same segments.
By integrating programmable hardware into the game, a puzzle can become interactive where the difficultly level can be adjusted either at the beginning of the play period or actively during the play period.
These and other aspects of the invention will be apparent from and elucidated with reference to the embodiments described hereinafter.
Hereinafter, the invention will be explained with reference to some drawings which are intended to illustrate the invention and not to limit its scope, and wherein:
In its original state, each face of the cube 1 is a different color, but the rotation of each face allows the smaller cubes (i.e. the segments 5, 7, 15) to be rearranged in many different ways. The location of the segments 5, 7, 15 relative to one another can be altered by twisting an outer third of the cube 1 90 degrees, 180 degrees or 270 degrees. The challenge is to return the cube 1 from any state to its original (i.e. solved) state, in which each face consists of nine squares of a single color.
The edge segments 5 show two colored sides each, and the corner segments 7 have three colored sides. Below, the sides of the segments, 5, 7, 15 that do not have a color, are referred to as interface sides. In the Rubik's cube embodiment, the interface sides are not visible for the user.
According to the invention, the colors of the colored sides of the segments 5, 7, 15 are determined by light modules inside the segments 5, 7, 15. The light modules are arranged to lighten certain parts of the segments 5, 7, 15. In an embodiment, certain parts of the segments 5, 7, 15 will be colored red, green or blue or any combination of the primary colors.
In an embodiment, each power cell 41, 42 is rechargeable and is connected to a RF receiver 43, 44 to allow wireless charging of the power cells 41, 42. The RF receivers 43, 44 may comprise a coil that inductively receives energy from an electromagnetic charging tool, not shown, known to the skilled reader. Each chamber 21, 22 may also comprise a communication circuit 47, 48 that allows each chamber 21, 22 of a segment 5 to communicate with chambers in other segments and become ‘aware’ of the neighboring segments. The communication circuits 47, 48 may comprise standard Altera Chips or other microprocessors known to the skilled person. The communication circuit 47, 48 is connected to its respective processor 33, 34 and also connected to a capacitive coupler 51, 52 as shown
Each capacitive coupler could oscillate at a specific frequency that would be representative of the segment. Upon detecting these frequencies, the processor of a chamber of a segment can get identification information of the neighboring segments. The identification information can be used by the processors to control the color of the respective chambers.
The segment 5 further comprises two transparent (or quasi-transparent) walls 36, 37 which are part of the outer faces of the cube 1 and thus visible to the user. The inner wall 30 may be reflective so that more light produced by the light modules 31, 32 will be directed to the outer walls 36, 37. In this way less energy is needed for the activation of the LEDs. In this embodiment, the interface sides 38, 39 of segments 5 are not transparent so that the radiation of the segment 5 is not influencing the color of a neighboring segment. However, in order to achieve special lighting effects, the interface sides may be transparent or partly transparent as well.
As will be clear to the skilled reader, this point of contact 81 is positioned so as to face another contact point present on the neighboring segment, not shown. Via connections like connection 80, the central processor 70 transmits signals to the edge segments 5.
The center segment 15 further comprises a connection 82 leading from the interface with the core mechanism 20 towards the interface at the upper surface of the center segment 15, see contact point 83. The neighboring edge segment just above center segment 15 will have a contact point that faces the contact point 83. It may also have another contact point connected to the same connections 82 for redundancy reasons. The center segment 15 also comprises a connection 85 between the interface with the core mechanism 20 and the light module 86 inside the center segment 15 itself.
The light modules 31, 32 may be powered by a central power cell 78, see
The connections 80, 82, 85 may comprise for example copper threads or any other suitable wiring known to the skilled reader. It is noted that instead of hard wired communications lines, the communication between the central processor 70 and the segments 5, 7, 15 may be wireless, by way of a transceiver inside the core mechanism 20. Preferably, each segment 5, 7, 15 comprises a power cell. In that case, there is no need for power lines coming from the core mechanism 20.
In a particular embodiment, one or more of the segment 5, 7, 15 are arranged to be in communication with an external programming tool 90, see
Since all the colored sides of all the segments 5, 7, 15 can produce a plurality of colors, the puzzle can be set electronically to any state. This allows the following features that are not possible in a static puzzle:
At a step 901 the central processor 70 switches on. Then in a step 902, the central processor 70 reads a color pattern of the cube 1 representing a hustled cube. Several color patterns may be stored in the memory 62 of the central processor 70. The central processor 70 randomly selects one of the stored patterns. Next in a step 903, the central processor 70 sends control signals to the light modules 31, 32 of all the segments 5, 7, 15. The light modules 31, 32 are arranged to produce the colors depending on the control signals sent by the central processor 70. In this simple embodiment, the central processor 70 will end its task. Now a user can rotate the different faces of the cube 1, in order to solve the puzzle. If the puzzle is solved, the user will notice.
In yet another embodiment of the game there is no central stationary section. An example of such an embodiment is a 3D puzzle made of segments forming the well-known 3D pyramid configuration mentioned above.
In an embodiment, all the segments 5, 7, 15 have power cells and are electrically linked together via contact wires so that the total power from the cells in the segment is shared. Dispersing the power attainable from the power cells over all the segment 5, 7, 15 like this prevents some segments dimming faster than others.
In an embodiment, communication between the segments is realized via modulation techniques over the power lines.
In another embodiment, the invention relates to a 2D puzzle. An example of such a puzzle is shown in
Alternatively, the color of an added tile can be a function of the new neighbors (and they might change as well). The most simple is to create a puzzle where the color of added tiles is simply a mix of the neighboring tiles e.g. one red and one blue makes two purple tiles. Example with six colors: Red (1), purple (2), blue (3), cyan (4), green (5), yellow (6). Place purple (2) next to green (5) and the new colors get closer to each other: purple (2) gets blue (3) and the green (5) gets cyan (4). The difficulty level of this game can be easily varied. If the new function/algorithm is not disclosed, part of the puzzle is to figure out how the tiles are reacting to each other (finding the rules). This in itself can be quite intriguing. Rather than homogeneous surfaces other patterns, or low-resolution images can also be used as the end-goal of the puzzle.
Another feature of such a puzzle is that it is possible that each cube could recognize its neighbors and be able to apply a simple (set of) rules. A set of rules can be compared to the set of instructions self-organizing (mini) robots get (keywords: swarm behavior, genetic algorithm, hormonal software). Finding out the rules and making new objects (even surprising ones) can be as much fun as solving a puzzle.
Many of the possibilities discussed for the Rubik's cube mentioned above, can also be applied in this embodiment as well. The software for controlling the behavior of the tiles can be updated to create new games/challenges for the same hardware. A light source you just have to play with comparable to the GeoMag game wherein a person puts some tiles on a table and other people will play with it and leave a nice looking result.
In an embodiment, a special segment is arranged to turn the game on or off. This dedicated segment will be recognized and turn all segments to a standby mode. Alternatively, the dedicated segment will turn off all segments after for example 10 minutes without any detected changes. These detected changes could be in a memory of the segments or in a specific central memory arranged in a central unit such as the core mechanism 20 shown in
While the invention has been described in connection with preferred embodiments, it will be understood that modifications thereof within the principles outlined above will be evident to those skilled in the art. The invention is not limited to the preferred embodiments but is intended to encompass such modifications. Furthermore, the invention is not restricted to segments having flat surfaces. It may well be used to manufacture marbles emitting light wherein the marbles interact if they get close to each other. The scope of the invention is only determined by the accompanying claims, wherein any reference signs used in the claims are not construed as limiting the scope of the invention.
