How to Play Stack Tower

Stack Tower is a timing-based puzzle game where you build a tower by dropping blocks at the right moment.

Tap or click to drop the moving block
Align it perfectly with the block below
Misaligned parts are cut off - your block shrinks!
Build as high as you can before the block disappears

Pro Tips

Perfect stacks (no overhang) keep your block full-sized. Watch the rhythm of the moving block and time your taps to the beat!

How to play

A block slides back and forth above your tower. Tap, click, or press Space to drop it onto the block below. Anything hanging over the edge gets sliced off, so every sloppy drop leaves you a narrower target. Land within a few pixels of center and the drop counts as perfect, keeping full width. The run ends when you miss outright or your block gets shaved too thin to land on.

Tips

Track the block's leading edge, not its middle. Edges are what get sliced.

A perfect drop snaps the block into line with the one below, quietly undoing small drift from earlier rounds.

Each new block enters from the opposite side, so move your eyes to the other edge after every drop.

Speed climbs with every block and tops out around block 50. If you survive that long, the rhythm stays steady.
