How scoring works
Only the ranked puzzle counts. Guests and practice puzzles aren't scored.
Points
Points = 1000 × accuracy × speed
- Accuracy = the fewest turns that solve the board ÷ your turns. Hitting that minimum (par) is 100%.
- Speed = 20 seconds ÷ your time. Solving in 20 seconds or less is 100%.
A perfect game, the fewest possible turns in 20 seconds or less, scores 1000. Because the two are multiplied, using 10% fewer turns is worth exactly as much as being 10% faster. Fast clickers and careful thinkers have the same chance, and the best scores go to players who are both quick and accurate.
On any one day, ranking by points is the same as ranking by time × turns: lowest wins.
Examples
On a puzzle that can be solved in 44 turns:
| Player | Time | Turns | Accuracy | Speed | Points |
|---|---|---|---|---|---|
| Fast clicker | 0:30 | 200 | 22% | 66% | 147 |
| Careful thinker | 2:00 | 50 | 88% | 16% | 147 |
| Fast and careful | 0:45 | 60 | 73% | 44% | 326 |
| Relaxed | 3:00 | 90 | 48% | 11% | 54 |
Leaderboards
- Points ranks the combined score. It's the main board.
- Fastest ranks time alone. Ties go to fewer turns.
- Most efficient ranks accuracy alone. Ties go to the faster time.
Each board has a Today view and an Overall view. Overall points add up every ranked day, so playing daily counts. Overall fastest and most efficient use your average time and accuracy, and you appear on them after 5 ranked solves, so one lucky day can't top them.
Boards list the top 100. When you're signed in, you also see your own place on each board, today and overall, wherever you rank, plus how many days you finished first and in the top 3 on that board. A day counts once it's over and at least 4 players have solved it, and players who tie share the place. Your finishes are only shown to you, and they don't add points.
Keeping it fair
- Signed-in players get one ranked puzzle a day, the same for everyone. Guests play a different puzzle.
- The ranked board stays hidden until you press Start, and your clock starts at that moment.
- The clock runs on our server and keeps going if you leave or reload.
- The server counts every turn you make and checks that the board is really solved.
- Solves faster than 10 turns a second across the whole puzzle aren't counted.
- Some puzzles have two solutions. Par is the fewest turns for the solution you found.
These numbers may be tuned as more people play. Points are always worked out from your stored time and turns, so any change applies to everyone's past games equally.
