Aim
Take turns removing one block from the tower and placing it on top, without the tower falling over.
Setup
Put the blocks on a flat surface. First build the tower: a layer of three blocks side by side each time, with every layer at right angles to the one below.
Play
Decide who starts. Take one block from the tower, from anywhere below the highest completed layer, and place it on top. Build the layers on top in threes as well, at right angles to the layer below.
Winner
The last player to place a block without the tower falling over.
