Topple Doodle: Domino Puzzle

Doodle a shape. Watch it topple everything. Topple Doodle is a physics puzzle about one perfect chain reaction. Every board is a machine of dominoes, ramps, levers and gates, with a chime waiting at the very end. Sketch a shape with your finger and it drops in as a real, solid object: a marble rolls, a block slides, a plank bridges a gap. Find the shape that sets the whole machine in motion, and watch it cascade, tier after tier, until the chime rings. There is no single right answer. A wheel, a wedge, a careful plank: if the dominoes fall and the chime rings, the solution is yours.
