To play craps, enter your bet in the text field and click the "Play" button. Bets will be rounded down to the nearest dollar because there's no change at the table. If you'd like to play the role of the house, uncheck the "I want to roll the dice" box. Otherwise, you'll play the role of the shooter.
On the come-out roll, the shooter wins on 7 or 11 and loses on 2, 3, or 12. Any other roll will set the point to that number. Once the point is set, the shooter must roll the point to win the game. Rolling a 7 at that point will lose the game.
