Solitaire vs Oddfish

Solitaire Chess is a single-player siege puzzle played on a hexagonal honeycomb board. Pick your side and outwit a sharp AI — every move is a plan. [How it plays] ‧ Two sides, two strategies: as the Attacker, break out from the center and thread along the honeycomb paths to land on any red goal node on the rim; as the Defender, wall the attacker in before it can escape. ‧ A real AI opponent, powered by Monte Carlo Tree Search (MCTS), with Relaxed and Standard strengths — it never plays soft. ‧ Adjustable board size: radius 10–20 — the larger the board, the deeper the play. ‧ A rule with depth: the Defender can leap diagonally across a complete hexagon. ‧ Multiple board themes you can switch instantly, mid-game. ‧ Touch-mode toggle: "Place" and "Move board" are separate, so panning and zooming never drops a stone by accident. ‧ Stats: win rate and match history at a glance. [Who it's for] ‧ Fans of abstract strategy — chess, Go, and tactics games ‧ Anyone who wants to sharpen logic and spatial thinking in a single match ‧ A quick brain workout for your commute or lunch break [Privacy & offline] ‧ Fully offline — no account, no network required ‧ No ads, no tracking, no personal data collected ‧ All records stay on your device only ‧ Independently built by Intoxicated Child Studio [Free to play, Pro to unlock] The game is free to play. A one-time Pro unlock (non-consumable, yours forever) opens up larger boards, the Standard AI, full stats history, and every theme. Customers who bought the earlier paid version are granted Pro automatically — no repurchase needed. Set your siege on the honeycomb

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.
