Knight Circuit

Knight Circuit is a classic chess puzzle, reimagined for your phone: move a knight so it visits every square on the board exactly once, using only legal knight moves.

HOW TO PLAY
Tap any reachable square to move your knight there. The board fills in as you go — plan ahead, because painting yourself into a corner means restarting or undoing your way back out.
TWO WAYS TO WIN
1. Open Tour — visit every square. Start anywhere, end anywhere.
2. Closed Tour — visit every square, then finish on a square one knight's-move from where you started, so the path loops back into a closed circuit. Harder, and only possible on certain board sizes.

SIX BOARD SIZES
Play on boards from 5×5 up to 10×10. Smaller boards are a quick warm-up; larger ones take real planning
DAILY PUZZLE
A fresh, fixed puzzle every day, the same for every player. Build a streak by coming back day after day.

TRACK YOUR BEST
Every board size and mode tracks your fewest moves and fastest time separately, so you always know what you're chasing.

HELP WHEN YOU NEED IT
Toggle an optional hint overlay that highlights which of your next moves are riskiest, based on the classic Warnsdorff's rule — on only when you want it.
