Drop blocks one by one to build the tallest tower — real rigid-body physics means one wrong move topples it all. Free, in your browser, no install.
免费使用 →Every block is a real physics body — gravity, collisions and momentum decide whether your tower holds or topples.
Line up drops dead-center for Perfect placements and chain them for escalating combo effects and rising pitch.
Steer with your mouse on desktop or tilt your phone (gravity sensor) on mobile — tap anywhere to drop.
Submit your block count and compete with players worldwide on the global Top ranking.
Blocks shrink and the tower climbs as you stack higher, ramping up the challenge round after round.
No install, no sign-up. WebGL rendering and physics run locally — free and privacy-friendly.
Read the one-line goal, tap Start Stacking, and a block appears hovering above the base.
Move your mouse (or tilt your phone) to slide the hovering block left and right over the tower top.
Click, press Space, or tap the screen to drop the block — it free-falls and stacks with real physics.
Aim for center to score Perfect combos. Keep going until the tower tips over, then submit your score.
