How to play Stack Tower

Stack Tower is the addictive block-stacking game: a block slides back and forth above the tower, and you tap to drop it. Whatever overhangs the block below gets sliced off, so every miss makes the next drop harder.

Controls

One input: tap, click, or press Space to drop the sliding block. Nothing else to learn — everything is timing.

Scoring and perfect drops

Land a block perfectly flush and you keep your full width, score a combo bonus, and — after several perfects in a row — even regrow lost width. Sloppy drops shrink your platform until you're trying to land on a sliver.

Tips

Watch the moving block's leading edge, not its middle: you're aligning edges, not centres. The slide speed changes subtly as you climb, so re-tune your rhythm every few floors rather than tapping on autopilot. If you've shrunk to a narrow ledge, calm greed beats panic: a few careful centred drops rebuild your combo, and the perfect-drop bonus can regrow the tower's width and save the run.
