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).
