Craps -- the best game in the casino

Rules of the Game:

First roll, 7,11 wins, 2,3,12 loses. Any other combination is called the point (6,8,5,9,4,10). Now if a 7 comes up before the point, you lose. If the point comes up before the 7, you win. There are many other side bets you can make, but this is the basic game. Ready to try?
