A pair of dice each having twelve flat surfaces and in which opposite surfaces lie in parallel planes is provided. Each die incorporates twelve light emitting diodes for illuminating respectively the 12 surfaces but interconnected with a central battery by way of gravity responsive switches in such a manner that only the topmost surface of the die will be illuminated after the die has been thrown and comes to rest on a flat surface.
In electronic random die, where a device electronically determines a simulated roll of a six-sided die (or two-sided dice), the circuit consists of a multi-position switch and related circuitry which allows the device to also simulate a roll of a die other than six-sided, namely four-sided, eight-sided, twelve-sided, twenty-sided, or one hundred sided. All of these die rolls are available on this one device.
A puzzle comprises a cube having translucent faces with a light source behind each face. Gravity-sensitive or orientation-sensitive switches such as mercury switches, are connected to an electronic circuit acting to compare the switching states and switching movements of the switches with a programmed sequence held in a memory to determine whether and which of the light sources to illuminate. In use of the puzzle the faces will light up when a predetermined sequence of rotations about three orthogonal axes are performed correctly to match the switching sequences with the stored sequence.
An electronic device actuated by a manually generated movement to generate two independent and random set of electronic pulses resulting in a display of two independent sets of dots or digits from one to six inclusive representative of a dice display.
A lamp can be thrown alight from a distance by the person using it. The lamp comprises a polyhedral casing, made of shockproof material, inside which is housed a source of light that emits pluridirectional beams.
Playing dice are provided with light emitting diodes in their interior together with a battery and master switch in each die. A light emitting diode is associated together with a gravity responsive switch in addition to the master switch for each die face, the arrangement being that the upward face of the die is illuminated after the dice are thrown. A storage housing is provided in combination with the dice, the housing including die receiving compartments having small projections for reception in small bores formed in one face of each die to open the master switch in each die so that there will not be drainage on the batteries when the dice are stored.
