Chessticize: Chess Puzzles

Build tactical intuition with focused chess practice—completely free, with no ads or paywalls.

Practice. Review. Improve.

Puzzle Sprints

Solve short, rating-matched puzzle sets against the clock. Build pattern recognition one focused Sprint at a time.

Arrow Duel

Compare two candidate moves in the same position. Choose the better move, reject the tempting blunder, and practice the opponent's reply.

Custom Practice

Create a Custom Run with the puzzle themes, pace, duration, and difficulty you want to train.

Review what you miss

Missed and unclear puzzles enter scheduled Review so they return when due. Replay completed puzzles and explore positions with on-device Stockfish analysis—without changing your Rating or Review schedule.

Track your progress

Follow separate Ratings for Standard and Arrow Duel, review recent Runs, and filter History to revisit individual puzzles.
