The person who built the tower goes first. The steps are then as follows:
- Using only one hand at all times, take one block each turn from any tower level other than the one below an incomplete top level
- Place the block at the topmost level of the tower
- The next player’s turn begins after 10 seconds or whenever they touch the tower, whichever comes first
- If a block is removed and not used, it must be replaced from where it was taken, unless doing so makes the tower fall
The game ends when a player’s move causes the tower to fall or a block to fall out of the tower (other than the one the player is moving).
