- Time-Weighted Puzzle Rating — each puzzle's rating weighted by the time spent on it, so a five-minute puzzle counts five times a one-minute one. Thirty quick warm-ups take less of the clock than three hard puzzles, so this reflects where the effort actually went rather than how many positions went by.
- SR
- Solve Rate; share of attempts solved without a wrong move, as a figure between 0 and 1.
Displayed players must have at least 10 puzzle attempts and must have solved a puzzle within the last 14 days. Solving one puzzle is enough to reappear.
