Stack Tower is a precision block stacking game that runs in your browser. Tap or click to drop each moving block onto the tower. The more accurate your timing, the taller your tower grows.
Stack Tower is built around a single mechanic — precision timing. Everything else follows from that.
A block slides back and forth across the screen above the tower. It moves faster as your score increases.
Tap, click, or press Space to drop the block. The overlapping portion lands on the tower. The rest falls away.
If you drop the block perfectly aligned with the one below, you earn a Perfect bonus and the block width stays the same.
Each imprecise drop trims the block width to only the overlapping area. Miss enough and the tower becomes too narrow to continue.
The moving block speeds up as your score increases. Each level raises the difficulty, requiring faster and more precise reactions.
Your best score is saved in your browser's local storage. It persists between sessions so you can track your personal record.

A coloured block slides back and forth above the tower. Watch its position carefully.
Tap, click, or press Space at the right moment to drop the block onto the tower.
Keep stacking. The game ends when a block misses the tower completely.
