Chess, but a little stranger. Oddfish starts with serious Stockfish chess, then changes one rule at a time. RattleFish loses confidence when you play well. GluttonFish grows stronger when you feed it pieces. Restfish makes moved pieces take a nap. Twenty-nine modes across six families turn a familiar board into something wonderfully peculiar. MEET GIL A small gold fish with opinions explains every mode, reacts to the game, and reviews the aftermath. PLAY YOUR WAY • Classic chess or 28 strange variations • Adjustable engine strength • Game history and PGN import • Optional move evaluation and hints • Carefully designed for iPhone and iPad Six modes—including Classic, RattleFish, FumbleFish, Restfish, GluttonFish, and ChapelFish—are free. A single Full Oddfish purchase unlocks every remaining mode. No subscription. PRIVATE BY DESIGN Everything runs on your device. Oddfish has no accounts, ads, analytics, or tracking and does not collect personal data. Stockfish plays the chess. Oddfish supplies the personality problem.
