Leap: Knight Tour Puzzle
Cover the board, one knight
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
One piece, one rule: move like a knight and land on every square exactly once. A new board every day — the same one for every player in the world.
One piece. One rule. You may only move the way a chess knight moves.
The goal is simple until you try it: cover the whole board, landing on every
square exactly once. Thirty-six squares on 6×6. A hundred on 10×10.
The difficulty is not finding a move. It is not walling yourself in twenty
moves before the end — when the board still looks open and the way out is
already gone.
A thousand-year-old puzzle, by the way. Al-Adli wrote solutions down in
9th-century Baghdad; Euler took it to the Berlin Academy in 1759.
THREE MODES
Apprentice — every reachable square shows how many moves would be left from it.
Not the answer: a way to learn to see the tight places.
Regular — reachable squares are simply marked.
Prodigy — no hints at all.
FIVE BOARDS
From 6×6 to 10×10. A smaller board is not an easier version but a different
problem: there is less room to be wrong.
STEP BACK
A mistake can be undone. Steps back are limited, so each one is a decision
rather than a free button. Finishing a board earns more.
WHERE IT WENT WRONG
Stuck? The game shows the exact move after which a full tour became impossible.
It is usually far earlier than it feels.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
The post-mortem is instant. Working out where the tour went wrong used to freeze the game for seconds on a full board; now it answers at once.
A stray tap no longer throws away that answer — a board that is over ignores taps, so missing the button by a few points costs nothing.
The stop button works straight from the game-over card, for when you would rather not start another round.
Light or dark now follows your phone's own setting on first launch.
