Drop moving blocks to grow a tower.
Tap or click the play area to drop. Space or Enter also drops the slab.
Build the tallest tower. Only overlapping width survives each drop.
Tower Stack is a timing drop. A new slab travels over the tower. Tap to drop it onto the piece below. Whatever hangs past the last slab is trimmed away, so the next piece has a smaller landing. If you miss the tower entirely, the stack ends. Height is the score. Keyboard Space and Enter drop the same way a tap does.
