Sets your puzzle rating back to 1200 and lets puzzles you've seen come up again. Mate classics progress is kept.
Puzzles come from real games played on Lichess (the Lichess puzzle database, free to use). Solve one on the first try without a hint and your rating goes up; the next puzzle is picked near your rating, or easier or harder with the Difficulty buttons. A wrong move isn't the end: you can keep trying.
One puzzle a day, the same for everyone on the same date. Only your first try counts (a wrong move, a hint or the solution counts as a miss, and a miss goes to Review). It doesn't change your puzzle rating.
Puzzle Rush: puzzles from real games, starting easy and getting harder with every one you solve. A wrong move is a miss and the next puzzle comes; three misses end the run. Rush puzzles don't change your puzzle rating; the ones you miss come back in Review.
Puzzles you miss in the trainer, and mistakes the computer finds in your games, come back here: after a day, then 3, 7 and 21 days. Solve one on the first try each time and it's learned; miss it and it starts over. Reviews don't change your puzzle rating.
Every puzzle is computer-checked: one key move forces mate in the stated number of moves. Any other move that still forces mate in time counts too. A dot marks puzzles solved on the first try without hints.
King and queen, king and rook, and king and pawn endings are played against endgame tables: every position is worked out, so the defence is perfect. The other mates are defended by a careful lone king; the rook endings by Stockfish on the website (or the built-in computer in the offline file).
You play the winner. Find their move first time for 3 points, on the second try for 2, on the third for 1. A hint makes a move worth 1 point at most. If a game ended in checkmate, any mate counts.
