Draw a single line through every square on a grid notebook. That's the only rule.
The line you draw is your biggest obstacle. You can't pass through a square twice. If you rush through, you'll inevitably leave a square behind and have to start over. Only when you stop and look at the entire board will you see the path.
There's no time limit. No reflexes are needed. There's nothing to rush you. It's up to you whether you solve it in one minute or twenty minutes.
■ Five Rules to Remember Without Reading
① Numbers — Pass through squares in the order of ①②③… and end the line at the last numbered square.
② Colored Sections — Pass through sections in one go. Once you leave, you can't go back.
③ Ice — It's slippery, so you can't turn at that square.
④ Arrows — You must turn at that square.
⑤ Walls and Empty Squares — Blocks you can't pass through, and squares removed from the board.
All rules are explained with diagrams, not text. There's nothing to read.
■ Two Ways to Clear
Reaching the last number earns you a ★1 clear. Filling in all the squares earns you a ★3. If you get stuck on a difficult board, you can take a ★1 and move on. Everything is recorded in the clear log, so you can go back later and try again for a ★3.
