Knight's Tour
Rules
The board is 10×10, and the corner cell already has a 1 on it. Place the numbers in order — 2, 3, 4, and so on — by moving a chess knight: two cells in one direction and one perpendicular. Each cell can be used only once.
Don't worry about getting stuck: if the knight has no moves left, just hit "Undo" — you can do this as many times as you like, with no penalty, and try a different path.
On "Novice" levels, all available moves are always highlighted on the board. On "Confident" levels, you can request a hint with a button when you need one. On "Master" levels there are no hints at all — just memory and calculation.
Only a fully completed route — all 100 cells — makes the leaderboard. Your completion time is recorded, so try to finish as fast as you can.
