A grid of points is constructed from the following four layers: A transparent membrane keyboard with a press-sensitive area at each grid point A layer of a uniform, translucent material below the membrane keyboard. A separation layer of opaque material below the translucent layer, which for each grid point has a circular hole with reflecting or very light walls. A PCB below the separation layer, on which two or more light sources per grid point are mounted, and also carries the circuitry to drive them. The four layers are held together, and the thickness of the separation layer is such that the light sources are not immediately below the translucent area, but some distance away. The membrane keyboard and the control of the light sources are both connected to a CPU with some memory which uses them to manage various games and puzzles.
A grid of grid points is constructed from the following four layers:
A grid as described in any preceding claim, where the layer of translucent material is made of High Impact Polystyrene.
A grid as described in any preceding claim, where the membrane keyboard has a dome above the surface for each grid point.
A grid as described in any preceding claim, where in one or more games the state of illumination changes periodically even if the players do not press any point
A grid as described in any preceding claim, where in one or more of the games in each period of time the CPU checks for each point how many of the eight points around it are illuminated, and accordingly decides if the point is going to be illuminated in the next period, the player(s) can also affect the illumination state of a point by pressing it, and the task of the player(s) is to keep some points illuminated as long as possible, or to cause all the points to be switched off as fast as possible.
A grid as described in any preceding claim, where in one or more of the games the CPU illuminates an additional point in each period of time, and the player(s) need to press the last point that became illuminated before the next point becomes illuminated
A grid as described in any preceding claim, where in one or more of the games the CPU illuminates a pattern of points and then moves it in each period of time by switching on one point near one of the illuminated points and switching off one of the illuminated points, and the players need to press one of the points while it is illuminated.
A grid as described in any preceding claim, where one of the games is the game GO.
A grid as described in any preceding claim, in which one of the game has these rules:
