The tower consists of 54 wooden rectangular bricks, in layers of 3, placed at right angles to each other. Each player in turn, removes one brick from anywhere below the highest complete storey and places it on the top of the tower, at right angles to the blocks immediately below it. A complete 3-block storey must be completed before starting another. Only one hand may be used at a time.

The last player to stack a block without making the tower tumble over wins.

The same game concept was published in 1984 by Fagus under the name "Hoppla - eins zuviel!"
