Sky Stack

Tap to drop the sweeping slab onto the tower.
Any overhang gets sliced off, so land close to keep your platform wide.
Perfect drops snap flush and build a combo. Chain three and the slab starts growing back.

📱 Tap to drop⌨️ Space

🎯 Objective

Build the tallest tower you can. Every slab placed is one point, and the run ends the moment a slab lands with no overlap at all.

📊 How you score

Every slab you place scores one point. A drop inside the perfect window snaps flush and builds your combo; from the third perfect in a row the slab regrows width on both axes, up to full size. Medals land at 15 for bronze, 30 for silver and 50 for gold. Your final score is the slabs placed when one misses completely.

💡 Tips

Watch the overhang, not the centre. The far edge tells you exactly how much will be sliced away.
Every drop plays the next note of the tune as you climb. Perfects add a brighter chime on top: plain piano means a near-perfect slipped by.
After a bad cut, slow down and chase perfects: three in a row starts winning your width back.
Later slabs sweep faster but never change rhythm. Count the beat instead of reacting to the slab.

How do I play Sky Stack?

A slab sweeps back and forth above the tower. Tap or click anywhere, or press Space, to drop it where it is. Whatever hangs over the slab below is sliced off and falls away, so each sloppy drop leaves you a narrower platform to land on. The run ends when a drop misses the tower entirely.

What counts as a perfect drop in Sky Stack?

Land within a few pixels of dead centre and the slab snaps flush with a chime, no slicing at all. Each perfect builds your combo. From the third consecutive perfect onward, every extra one regrows the slab a little on both axes, up to full size, so a comeback is always a few clean drops away.

Does Sky Stack get harder as I climb?

Yes. The slab sweeps faster with every point, from a gentle two-second crossing to nearly twice that pace, but the rhythm never changes and the perfect window stays the same size. Medals land at 15, 30 and 50 blocks for bronze, silver and gold.

Can I race a friend on the same tower?

Yes. Share a challenge link after a run and your friend gets the exact same tower: identical colours, identical sweep directions and speeds, so the score battle is perfectly fair.
