TWO FREE TOURNAMENTS, EVERY DAY 7:00 PM — The Arena. A rated 60-minute tournament. Join any time, play as many games as you like, climb the standings. 9:00 PM — Puzzle Battle. Two minutes, everyone starts together, one shot at the top score. Free entry to both, every day of the week. WEEKLY LEADERBOARD Every Monday the leaderboard resets and everyone starts level again. Finish in the top three and we'll send you a CircleChess T-shirt. PLAY Rated games in blitz, rapid and classical time controls, against players at your own level. Challenge friends directly. Fast matchmaking and a clean, responsive board. PUZZLES Puzzles sorted by theme and difficulty, so you train the patterns you keep missing rather than random ones. Track your puzzle rating as it moves. LEARN Structured courses from beginner to advanced — openings, middlegame plans and endgame technique. Built by titled coaches rather than recycled from elsewhere. Suitable for children learning the game and for adults returning to it. ANALYSE Instant computer analysis after every game: where it went wrong, what the stronger move was, and why it was stronger. You can also upload your over-the-board scoresheets and get the same analysis on your offline tournament games. CLUBS AND TEAMS Join a club, play for your team, and compete on club leaderboards.
