Stack Tower

Stack Tower is the purest expression of timing-based gameplay. A block swings horizontally above the tower you're building; you tap to drop it; the overhang gets cut off and the next block is slightly narrower. Keep stacking until you miss completely and lose. The genius is in the simplicity — there are no upgrades, no power-ups, just you and the rhythm of perfectly-timed taps.

Tap anywhere on the screen to drop the swinging block onto the tower. Any portion that doesn't overlap with the block below gets sliced off and falls away. If your drop is perfectly aligned (within a small tolerance), the block stays full-width and you can keep building wider. Miss completely (no overlap at all) and the game ends.

Slow your tap. Most players over-anticipate and tap before the block is centered. Watch the shadow under the block and tap when the shadow exactly aligns with the tower below. Perfect alignments restore lost width — chain a few perfects in a row and you'll undo earlier mistakes. As the tower grows taller and faster, breathe and find a tap rhythm — the speed-up is steady, not sudden.

Stack Tower works because it's a game of pure micro-timing. You either nail it or you don't, and your performance improves measurably every session. The visual reward of watching your tower climb past the clouds, plus the rising tension as the camera zooms out, makes every personal best feel earned.

For fans of one-tap arcade classics. Easy to pick up between meetings or while waiting for coffee. The session length is whatever you make it: a one-block run or a hundred-block tower.
