How to play

Slab Stack is a stack game online that needs only one tap. A slab slides back and forth above your tower; tap to drop it. Whatever hangs over the edge gets sliced off, so every miss makes the next slab smaller.

Land a perfect drop and the slab keeps its full size. Chain perfect drops, keep a steady rhythm and see how tall your tower can get before the slabs run out of room.

Controls

Desktop

Click or press Space to drop the slab.

Mobile

Tap anywhere to drop the slab.

Tips

1Watch the slab, not the tower — tap when the edges line up.
2Perfect drops keep the slab at full width.
3The slabs speed up as you climb, so keep your timing relaxed.
