Don't tip over
A plank rests on a rock above a still lake at dawn. Drop smooth zen stones on it and keep it level; three stones of a kind that touch become one bigger, heavier stone.

Slide your finger to aim the hanging stone and let go to drop it. The plank turns on the rock, so balance the weight on both sides.
