About Tower Stack
Tower Stack is a one-tap precision game. A block slides back and forth above your tower and you tap to drop it. Any overhang is cut away, so the tower gets narrower with every sloppy drop. Land blocks perfectly to keep the full width.
How to play
- Tap the tower or press Space to drop the sliding block.
- Only the part that overlaps the block below stays.
- Build the tower to the target height without missing completely.
Tips and strategy
- Drop as the block crosses the centre of the tower, not at the edge.
- Perfect drops keep your width, so aim for them.
- Speed increases as you climb, so keep a steady rhythm.
Levels, stars and XP
Finish a level to earn one to three stars and XP towards your player level. Replay any unlocked level to improve your stars. From level 151 the game enters endless mode, where each level is a remix of an earlier one with fresh colours and a slightly higher difficulty.
