Rules of Snake Eyes (small variation on game called Craps in USA)
Player rolls two dice.
On the first roll if the total of the dice is
2 (snake eyes): player wins and receive 2 points
7 or 11: player wins and the player receives 1 point
3 or 12: player's loses and the House (the computer) receives 2 points
4, 5, 6, 8, 9, 10: this total becomes your possible points that you will receive if you win. To win, you continue to roll the dice until you roll your possible points value a second time. However if you throw a total of 7 before throwing your possible points value, you lose and the House receives 2 points. Rolling a total which is not equal to 7 or your possible points value in these subsequent rolls has no effect on the game, you simply roll again.
In the screen shot on the next page, the player rolls a total of 4, so rolls again and luckily rolls a 4 and so wins. In the next game, rolls a total of 4 (pure coincidence!) and then has to do successive rolls until rolls a 4 and so now has 8 points total.
