The game consists of 36 6-sided dice.
At the start of the game, all 36 dice are rolled. Each player takes a die that shows a 1 and puts it in front of him/herself. Then he/she takes a die showing a 2 and stacks it onto the first die. This continues until the 6 has been reached, then it's back to 1. All players act simultaneously and each player is only allowed to take one die at a time. Sooner or later, a player won't be able to find a dice with the correct number. He/she has to wait until the other players are also stuck. The left-over dice are rolled again. If a tower topples over, the dice are put into the pool for the next roll.
The game ends when all dice have been stacked. The player with the highest tower wins the game.
