Bot Stack
A wobbly physics stacker. Drag little robots onto the pedestal and pile them past the mint line without toppling the tower. Clear each level to earn stars.
How to play
Drag a wobbly little robot onto the pedestal and let go. Each bot settles with real physics, so the tower sways, leans and wobbles as the pile grows.
Stack the bots past the mint goal line without toppling the tower to clear the level. Reach it cleanly and you earn stars, saved in your browser, no account needed.
Meet the crew
Bots come in assorted shapes and sizes: squat and wide, tall and tippy, and open-topped bucket bots that smaller robots can nest right inside. A wide, flat one makes a far better base than a tall, narrow one.
Power-ups
From the second level on you're handed a few power-ups. Arm one and it's applied to your next bot before you drop it. Spend them where a shaky tower needs the help.
The climb
Twenty levels take you from your first careful stack to a storm-tossed tower. Each new stretch adds a fresh twist: the power-ups above, and later a wind that shoves the whole pile side to side.
Clear a level to unlock the next, and your best stars are saved in your browser. Chase all three on every level, no account needed.
Tips
- Place each bot low and centred before reaching for height.
- Let the tower settle between drops. Don't rush a wobble.
- A wide, flat base holds far more than a tall, narrow one.
- Save the magnet for a shaky joint near the top, where a weld counts most.
- On windy levels, keep the tower squat and heavy so gusts can't tip it.
