A familiar game. An unfamiliar board. Almost Chess is a chess variant with randomized starting positions, so you can focus on the position in front of you instead of memorized openings. PLAY YOUR NEXT MOVE Face AI opponents selected for your in-game rating. Tap a piece to see its legal moves, find tactical opportunities and work toward checkmate. Your rating tracks progress inside Almost Chess; it is not an official chess rating. A NEW CHALLENGE TO RETURN TO Try the daily challenge with three attempts per day. Weekly challenges rotate board restrictions for a different way to play. In the Gauntlet, each win brings a stronger opponent; a loss ends your run. Gauntlet games do not allow undo. MAKE THE BOARD YOURS Explore random boards with no queens, mirrored positions, pawns or extra chaos. Choose from 12 board themes and track your statistics and achievements. LANGUAGE OPTIONS Play in English, Korean, Japanese, Simplified Chinese or Traditional Chinese. Follow your device language or choose a language in Settings. ADS AND OPTIONAL PURCHASE Full-screen ads may appear between completed games. Eligible single-player games start with one free undo; you can choose to watch a rewarded ad for one more undo when an ad is available. The optional one-time Remove Ads purchase removes ads and gives unlimited undos in eligible single-player games. It does not add undo to the Gauntlet.
