Border Chess is chess with room to breathe. The board is 10×10: standard FIDE chess on the inner 8×8, plus one empty square on every side. Kings, queens, and edge pawns can use the border for extra maneuvering — same rules you know, with new tactical possibilities. PLAY VS BOT Challenge Fairy-Stockfish, tuned for the border board. Choose your difficulty and improve your game against a strong computer opponent. PLAY WITH FRIEND Pass-and-play on one iPhone. The board automatically flips each turn so both players see the game from their side. BUILT FOR CHESS PLAYERS • Standard rules: castling, en passant, promotion, check, checkmate, stalemate, 50-move rule • Legal move hints, last-move highlight, and check highlight • Clean, modern board inspired by chess.com • Portrait mode, optimized for iPhone NO ONLINE MULTIPLAYER (YET) v1 is offline on your device — bot mode and local two-player only.
