A balancing tower building game. Apparently based on an African game. It is very similar to Jenga, but predates it. You build a tower out of the narrow edges of 50 wooden blocks. Each level has three blocks, and the next level is built at right angles to the previous level. Each player takes a block from below the top and transfers it to the top level. Players can use two hands, but no physical interaction between the players is allowed. The player who makes the tower fall loses. Everyone else wins.
