About this game

Stack is the one-tap tower game that's impossible to put down. A block slides back and forth above your tower — tap at the right moment to drop it. Land it dead-centre and it locks on at full width; land it off and the overhanging edge is sliced clean off, leaving you a narrower block to aim with next time. Miss the tower entirely and it's over. The tower climbs, the blocks speed up, and every level is a little harder than the last, so a steady rhythm beats a hurried one. String together perfect drops and you'll even claw some width back, rewarding precision over luck. It's the kind of game you pick up for one quick run and look up ten minutes later chasing your best height. The neon tower shifts colour as it rises, so every tall run looks a little different. One control, endless replay — tap, click, or press space, on any screen, with nothing to install.

Controls

Tap, click, or press Space (or Down) to drop the moving block. That's the only control — timing is everything.

How to play

A block slides side to side above the top of your tower. Drop it so it lines up with the block below.

Any part that hangs over the edge is sliced off and the block gets narrower.
Drop it perfectly centred to keep full width, and chain perfect drops to grow the block back a little.
Each block you land adds to your height and the pace quickens.
If a drop misses the tower completely, the run ends — so build a rhythm and go for a new best height.
