Leaderboard

The best runs of the day and of the week, at each difficulty. No account needed — finish a puzzle, type a nickname, and you are on the board. Entries rank by score, and a faster time breaks a tie.

How the ranking works

Your score is 10 points per square you filled in yourself, plus a difficulty bonus, plus a speed bonus for every second under par for that level — minus 50 per mistake and 75 per hint. Scores are recalculated on the server from the details of your run rather than taken on trust from the browser.

The daily board covers one UTC calendar day; the weekly board runs Monday to Sunday in UTC. Using UTC for both means everyone competes on the same board no matter where they are. Entries are removed automatically a few days after their board closes.

Want a better placing? The techniques guide is where the time savings actually come from — the speed bonus rewards clean scanning far more than fast clicking.
