In this game, the user competes against the computer. On each turn, the player rolls a pair of dice and adds up their points. Whoever reaches 100 points first, wins. If a player rolls a 1, they lose all points gained that round. If a player rolls a pair of 1s in one roll, the player loses all points earned so far in the game. The player may voluntarily turn over the dice after each roll. So the player must decide to either roll again (be a greedy pig) and risk losing points, or give up the dice, possibly letting the other player win.
