Contributing expert Michael "The Wizard of Odds" Shackleford answers:
A law in California states dice alone cannot determine the outcome of a bet. So what they California casinos do is shuffle one 6-card deck for each die, each deck comprising cards valuing 1 to 6. Then two dice -- I believe of different colors -- are rolled, and the "nth" card is turned over in each deck, where "n" is the number rolled for that deck.
For example: If the player rolled a 2 and 5, then the 2nd card would be turned over in one deck and the fifth in the other. The cards turned over represent a throw of the dice. Mathematically speaking, the odds are the same as in regular craps.
