Abstract

An electronic die capable of exhibiting visual and/or sound effects is disclosed. The die retains the conventional dice-action aspect of being rolled to randomly select an upwardly facing facet. The electronic components provide entertainment effects. Electronic displays, which can include light-emitting dots, are located on the sides of the die for showing the visual effects. An electronic circuit, contained within the die, controls output of the displays. One or more batteries are also contained inside the die for powering the displays and the electronic circuit. To ensure that the die is suitable for playing dice games, the displays, electronic circuit and batteries are securely mounted to withstand the die being thrown. The die can have a hollow compartment for holding the batteries and electronic circuit, or alternatively, the die can be formed using injection molding or casting techniques to embed the electrical components in a solid plastic body.
