FAQ
How do I play Stack Tower?
There's only one action: stop. Tap or click the screen, press Space (or Enter), or press the Stack button, and the sliding block stops right there and lands on the tower.
Why do the blocks get narrower?
Only the part that overlaps the level below stays; anything hanging over the edge is sliced off. The next block is narrower by however much you missed. When there's no overlap left (width under 6px), the game ends.
What happens if I stop it perfectly?
If you're within 2px, it's a Perfect. The block keeps its width and even grows a little (2px). Even after your blocks get narrow, a string of Perfects can bring them back to the width of the base.
What's the difference between the levels?
"Normal" starts sliding at 105px per second, and "Fast" at 150px per second. Both get faster with every level you stack. Your personal best is saved separately for each.
Why is there no leaderboard?
This site only accepts records that the server can verify by replaying your moves. In Stack Tower the exact moment you stop is the record itself, so it can't be verified this way, and the game is practice only. Your personal best is saved in this browser.
