Tip: a PERFECT drop keeps your block full size — chain them for bonus points.
Stack Rush — a free, addictive stacking game you can play in your browser
Stack Rush is a fast, minimalist arcade game with one rule: tap to drop the moving block on top of the tower. Any part that hangs over the edge gets sliced off, so every sloppy drop makes your tower thinner — and one bad tap ends the run. Land a drop dead-center and it counts as a PERFECT, keeping your block at full width and building a combo multiplier for bonus points.
There's nothing to download and nothing to sign up for. It runs instantly on any phone, tablet or computer, which makes it the perfect time killer for a queue, a commute or a boring meeting break. Games last seconds, so "just one more try" turns into twenty.
How to play
- Tap the screen (or press Space/Enter on a keyboard) to drop the moving block.
- Whatever overhangs the tower is sliced off — your block gets narrower.
- Drop it dead-center for a PERFECT: no slice, combo up, bonus points.
- Chain perfects to slowly regrow your block back to full size.
- The tower speeds up as you climb. Miss completely and it's game over.
How to keep the tower wide
A drop counts as PERFECT within 7 pixels of dead-center — more forgiving than it looks once the block is moving fast. Chaining perfects is the only way back to full width: each one after the first regrows the block by 6 pixels, so a run of four or five can rebuild a tower you'd sliced down to a sliver.
The side-to-side speed climbs roughly 3.6× from your first drop to around block 67, then stops rising entirely. Past that point every drop is exactly as fast as the last, and the only thing left to lose is your rhythm. Tap on the beat rather than chasing the center: a careful drop keeps the block the same width, and only a perfect regrows it.
