Puzzles & training

The daily puzzle is one new tactical challenge picked every day, the same puzzle for every player worldwide. Solve it for a streak — solving on consecutive days extends the streak, missing a day resets it. The streak counter on your profile is one of the simplest ways to track training consistency. Daily puzzles don't affect your puzzle rating.

Puzzle Rush is a timed mode: solve as many puzzles as you can before time runs out. Each round is 3 or 5 minutes, and any wrong answer ends the run. The leaderboard ranks the top scores. It trains pattern-recognition speed under pressure, which transfers directly to bullet and blitz games. Puzzles in Rush escalate in difficulty as you go.

Yes — your puzzle rating is separate from your game ratings and tracks your tactical strength. Solving a puzzle above your current rating raises it; missing one below your rating lowers it. The system uses Glicko-2 just like game ratings. The rating updates after every puzzle in regular solve mode, but not in Puzzle Rush or daily-puzzle mode.

Yes — the Puzzles page has theme filters for forks, pins, skewers, mate-in-N, back-rank patterns, deflection, sacrifices, endgame motifs, and many others. Pick a theme to drill that pattern specifically, or leave it on "All" for a mix tuned to your rating. Themed sets are useful when you've identified a weakness in your own play and want to target it.

The opening trainer drills your repertoire move by move, using spaced repetition. Pick an opening — Ruy Lopez, Sicilian, Queen's Gambit, and dozens more are available — and the trainer plays you through the main lines, asking for your move at each step. Mistakes return more often; correct answers fade out. Over time, your repertoire becomes automatic.

The coordinate trainer is a quick drill that improves your board vision. Squares light up and you click them as fast as you can — over a 30-second round, the score is how many you got right. The leaderboard tracks high scores. It's a small tool but it sharpens an underrated skill: many tactical mistakes come from misidentifying a square.
