Three minutes on the clock and three lives. Every puzzle you solve scores a point, and a wrong move costs a life.
Rules
- The clock runs for three minutes from the first puzzle.
- Every puzzle you solve scores a point.
- A wrong move costs a life, and you go straight on to the next puzzle. Three mistakes and the run is over.
- The first puzzle is easy, and they get harder as you go.
- No hints, no solutions. Just you and the board.
Challenge someone
Every run has its own code. When you share your score the code goes along in the link, and whoever opens it gets exactly the same puzzles in the same order. Then only skill tells you apart. Your record is kept in your browser, nowhere else.
Would you rather take it easy? There are puzzles by theme with no clock, and the daily puzzle every day.
The puzzles come from Lichess, fetched on October 2, 2026. After the run you can see how each one went.
