How to Play Stack Tower
Stack Tower is a timing game where you build upward one moving block at a time. Press Start Game and watch the active block travel from side to side. Tap, click or press the Space bar when the block lines up with the one below it.
Only the overlapping part of the new block remains. If your timing is slightly off, the next block becomes narrower. If a block misses the tower completely, the round ends. This makes early accuracy important because a wider tower gives you more room for later placements.
Difficulty Levels
Beginner moves the active block slowly, Intermediate uses a moderate pace, and Advanced moves it faster. The scoring and overlap rules are the same at every level.
Stacking Tips
- Watch the leading edge of the moving block and compare it with the block below.
- Aim for consistent near-center drops instead of trying to correct a large error in one move.
- As the tower narrows, use smaller timing adjustments.
- Focus on rhythm; repeated movement speed can help you anticipate the ideal drop moment.
