Match the bottom arrangement to the top (goal). Three pegs hold different numbers of balls: Peg 1 fits 3, Peg 2 fits 2, Peg 3 fits 1. Only the top ball on a peg may move. Drag a ball to another peg, or tap a top ball then tap a peg to move there.
← BackLower move count (closer to minimum) and faster completion indicate stronger planning.
