Hanoi Rush

Move the tower. Beat your best.

Hanoi Rush turns the classic Tower of Hanoi into a speedrun. There are only three rules: move one disc at a time, only the top disc, and never place a larger disc on a smaller one.

Ten seconds to learn. Days to shave off a single second.

■ Three to nine discs, all free

Three discs take 7 moves at minimum. Nine take 511. Nothing is locked, nothing is sold. Every difficulty is open from the first launch.

■ Records exist to be cut

Each difficulty keeps your ten best runs with times and move counts. Pick the same board back up, trim a few tenths, watch the list shift. That is the whole game.

■ 42 medals

Every difficulty has six tiers: Clear, Bronze, Silver, Gold, Platinum and Master. The top two only count runs solved in the minimum number of moves. Speed alone will not get you there.

■ No account, no sign-up, no waiting

Nothing to register. Nothing to sign into. Open the app and you are already playing. Your records live on your device rather than a server, and the game runs just the same in airplane mode.

■ Controls that stay out of the way

Tap a peg to lift a disc, tap another to drop it. Lifting, dropping and breaking a rule each feel different in your hand.

■ Pixel art and synthwave

Discs and letters are aligned to the pixel grid. Move the tower over a neon grid at sunset.

■ English and Korean

Fully translated, from the menus to the leaderboard.

Start now. A run takes seconds. Cutting those seconds takes days.
