Stack
About Stack
The addictive block-stacking arcade game. A colourful block slides back and forth — tap at exactly the right moment to drop it onto the stack below. The more you miss, the narrower your blocks get. Nail the timing for a PERFECT! bonus and keep your stack wide. Miss completely and it's game over. How high can you go?
How to Play Stack
- Watch the coloured block sliding back and forth.
- Tap (or press Space) to drop it onto the stack below.
- Only the overlapping part stays — the rest falls away.
- Land it perfectly for a bonus and to keep the full width.
- Miss completely and the game is over!
Frequently Asked Questions
What counts as PERFECT?
If your block lands within 4 pixels of perfect alignment with the one below, you get PERFECT! and no width is lost — plus 2 points instead of 1.
Why do my blocks get narrower?
Each mis-timed drop trims the block to only the overlapping area. Stack up misses and your landing zone shrinks.
