How to play Wobble tower

Wobble tower is a physics stacking game. A crane swings a block back and forth above your tower. Tap or press the action key to release it, and the block falls and lands with real physics, so it can slide, tip and wobble. Drop each new block so it balances on the ones below. The taller you build, the more the tower sways, and gusts of wind push it around too. If the tower topples or a block falls off, the run ends. See how many metres you can climb.

Tips

Drop blocks centred, an off-balance block makes the whole tower lean
Wait for the swing to slow at the edges before you release
Let the tower settle after a wobble before adding the next block
Build a wide, steady base, height comes later

About Wobble tower

Wobble tower swaps clean arcade stacking for messy, satisfying physics. Nothing snaps into place, so every block you drop has to actually balance, and the wind makes a tall tower feel genuinely fragile. It is equal parts construction and nerve. Free, no download, plays in your browser.
