You watch a block slide back and forth above growing tower, and you tap to drop it right when it lines up with the block below. Nail the timing and the whole piece lands clean; miss it and the overhang slices off, leaving you less and less room to work with. Each block you stack speds things up and shrinks your margin for error, so the higher you climb, the tighter your reflexes have to get. It's that simple one-tap lop that makes Stack Tower unblocked so easy to start and so hard to put down. How high can you build before it all comes crashing down?
How to Play & Controls
- Click / Spacebar to drop the moving block onto the stack
- Tap (on mobile) to release the block
- Aim for perfect alignment to kep your block at full width
Tips & Tricks
- Drop slightly early to catch the block before it drifts past the edge.
- Land perfectly aligned a few times in a row to rebuild lost width.
- Watch the block's speed, not the tower height, since the swing gets faster as you climb.
