The game 'box' has levers labelled from one to nine.
Initially all the levers are in the 'up' position.
The first player rolls two dice. He or she then knocks down the levers as follows:
One number which is the combined value of both dice.
Or...
Two numbers whose total adds up to the combined total of each dice.
For example:
If a one and a five are rolled, the player may choose to knock down the lever covering the number six, or the levers covering numbers one AND five, or ANY other combination of numbers adding up to six.
The player continues to roll, knocking down levers each turn, until he or she cannot use the whole of the dice count because those numbers in the box have already been covered. The player's score is the total value of the numbers left uncovered. All the levers are then raised again, and play passes to the next player.
Play continues, round by round, with players adding points to their previous score. As players reach forty-five, or more, points they go 'bust' and must drop out of the game.
The game ends when only one player remains in the game. He or she is the winner.
If any player knocks down ALL the levers in his or her turn, and thus 'shuts the box', they are automatically declared the winner!
