A slab glides over your tower — tap to drop it. Overhang gets sliced away, perfect drops chime and combo, and the sky shifts colour as you climb. One button, endless one-more-go.
About Sky Stack
Sky Stack is pure precision distilled into one button. A coloured slab glides back and forth above your tower; tap and it drops exactly where it is. Land it flush and the tower climbs clean. Land it off-centre and the overhang is sliced off and tumbles into the void — and every slice makes the next slab smaller, until you're threading a sliver onto a sliver at speed. The magic is in the perfects: nail a drop dead-centre and a ring of light bursts from the landing while the chime climbs a note higher with every one you chain, like a scale rising with your tower. String five or more together and your slab starts growing back, clawing back the width you lost — the one mercy on offer, and the skill that separates a lucky run from a great one. With its shifting sky, isometric candy-coloured tower and instant restarts, this is the stacker you keep retrying long after you meant to stop.

How to play Sky Stack
A slab slides back and forth above the tower. Tap or press Space to drop it onto the layer below. Any overhang is sliced off and falls away, shrinking your slab, but a perfectly centred drop keeps it full size and builds a combo. Chain five or more perfects and the slab starts regrowing. The run ends the moment a drop misses the tower completely.
Controls
Tap or click anywhere, or press Space, to drop the slab. Press M or the speaker button to toggle sound.
Tips & tricks
- Watch the slab's leading edge, not its centre — line the edges up and the middle takes care of itself.
- The slab moves at a steady speed, so lock into its rhythm and drop on the beat instead of reacting late.
- Perfect drops chime at a rising pitch — treat the melody as proof your timing is dialled in.
- Protect a combo past five at all costs: that's when the slab regrows, and it's the only way to win back width you've sliced away.
