On the first roll of dice: You win with a roll of 7 or 11. You lose with a roll of 2, 3, or 12. If you win or lose the game starts over. If you roll a 4, 5, 6, 8, 9, or 10 on the first roll, you don't win or lose. You receive what is called a point. The point is equal to the number that you rolled. If you receive the point, the game is not over and the dice are rolled again.
When they are rolled again: You lose with a roll of 7 and you win if you roll your point. If you don't roll a 7 or your point, you keep rolling until you win or lose.
