Place the support where you think the shape will balance. Drag the coloured shape left or right over the support, drag the orange support itself, tap the canvas, or use the slider. Use arrow keys on the slider for fine adjustments. If the starting position looks right, release it immediately—no movement is required.
Shapes grow from randomly joined pieces, branches, and cut-outs, without a repeating family cycle. Unlimited mode rejects close matches to your saved shape history on this browser. Daily challenges use a two-year collection screened for similar silhouettes and are the same for everyone; archive replays intentionally show the original shapes. Clearing browser data resets history. All solid material has uniform density; holes weigh nothing. The thin tray is weightless and simply carries the shape. Find the centre of gravity of the coloured material.
Countries mode has its own daily challenge, archive, and practice deck. Each outline uses the largest continuous landmass, north-up; separate islands are omitted. Balance the visible flat silhouette, not population or terrain.
Choose Standard or 10-second difficulty above the game. Timed rounds start only when you press Ready; at zero the current position is submitted. Switching tabs or reloading does not reset the clock. Sudden death requires at least 700 points each round. Friend links contain the same five puzzles and difficulty, with a first attempt saved on this browser.
One guess per round. Five rounds. Up to 1,000 points each. Error is measured as a percentage of the object's width; points decrease exponentially with error. The tilt is an illustrative reveal.
