How it plays
Tap a peg to lift its top disc and tap another to drop it, or drag the disc across. Pegs answer to the 1, 2 and 3 keys too. An illegal move shakes the peg and costs nothing.
Modes
Free Play from 3 to 10 discs with undo, hints that highlight the best next move from wherever you are, and Watch Solution to see it solved. Challenge climbs from 3 discs to 8 with a move budget per level, no undo and no hints.
Scoring
Challenge scores each level on how close you came to the minimum number of moves, with a bonus for beating par time and 500 points for clearing all six. Run out of moves and the run ends. Best scores go on a shared leaderboard.
What it tests
Whether a puzzle with a known perfect answer can still be fun to play. The minimum doubles with every disc — 7 moves for three, 255 for eight.
