Many games involve tossing a pair of dice. Here is a littleBits Arduino sketch that simulates tossing a pair of dice for two players. Of course, if there are more that two players, then the dice can be shared, as in any game with real dice. Each player simply pushes his or her button, and the results of the toss of the pair of dice are displayed as the two digits on a number module.

See the alternate image on the left for which each player has a mounting board with his/her button and number module attached.
