Drop swinging crates onto a tiny platform and build a tower that wobbles and leans with real rigid-body physics. Stack clean, keep your balance, and don't let the pile topple off the edge.
This is a true physics balancing game, not a timing trick. Every crate dangles from a crane, swinging side to side, and the instant you drop it, gravity takes over: it tumbles, slides, catches an edge, and nudges the whole stack off-true. No forgiving snap-to-grid here. A crate that lands a touch off-centre will lean, and a lean high up can send the tower groaning over the side of the platform. So land near the middle for bonus points, keep an eye on the dashed danger lines on either side, and learn to read the rhythm of the swing before you commit. It runs entirely on its own, with no internet, no images, and no tracking; the crates are drawn in code and the clicks and thuds are synthesized live.

A crate swings back and forth above the platform on a crane line. Tap the screen or press Space to release it, then watch the physics decide where it lands. Centred drops stay flat and stable. Off-centre ones lean and can drag the whole stack toward the edge. Each crate you settle adds to your tower and your score, with extra points for clean, well-aligned landings. The run ends the moment any crate slides or topples off the platform, so keep the whole pile balanced as it climbs.
Tap the screen, or press Space or the Up arrow, to drop the swinging crate. Press M to toggle sound. The view scrolls up automatically as your tower grows.
