More of a carnival game than anything else (no gaming commission in the world will allow it), Chuck-a-luck is a simple game. There is a cage containing three dice. Players have the option of betting on the numbers (1-6). Should one of your numbers come up once, you get paid even money. Should one of your numbers come up twice you get paid 2-1. Should your number come up three times, you get paid 3-1.
The game keeps on going like this. Even an elementary examination will find that the game's expected value (barring loaded dice, which are common), is far worse than that of any other table game. The game is sometimes used as a fundraiser for charity, but the odds of coming away with more money than originally put in are quite small.
