Chess Citadel is a free chess game you can play online in your browser, with no download or sign-up needed. It follows full chess rules inside a living cartoon citadel, where four named opponents wave hello, think out loud and gasp at your big captures.
Climb the ladder from cheerful Milo (Novice) through Aunt Rosa and Captain Theo to Grandmaster Zara (Hard). Beat each one to unlock the next and earn up to three stars against every opponent. There is also a daily checkmate puzzle, a 12-step Puzzle Path that teaches classic mates, and a two-player mode for a friend on the same device.
Legal-move highlights, hints, undo and a live move list make it friendly for beginners, while the stronger opponents give club players a real game. It runs on phones, tablets and computers. Chess Citadel is an original game made by the GamesYap team. For a quicker strategy duel, try Disc Drop Duel.
Yes. Chess Citadel is free to play in your web browser, and there is nothing to download or install. You get every opponent, the daily puzzle and the Puzzle Path at no cost. Coins only unlock board styles.
