The game has 2 players, playing in turns. In each turn, a player rolls the dice as many times as he whishes. Each result gets added to the CURRENT score BUT, if the player rolls a "1" on ANY dice, then the CURRENT score is erased. After that, it's the next player's turn. The player can choose to 'Hold', which means that the CURRENT score gets added to the GLOBAL score. After that, it's the next player's turn. The first player to reach 100 points or the entered final score on the GLOBAL score wins the game.
