Surround the board, turn captured pieces, and plan for the corners in a thoughtful offline strategy game.

Play a complete 8×8 bracket-and-flip match against a local strategy opponent or take turns with another player on the same device. A move is legal when it traps one or more opposing pieces between your new piece and another of your color. Captured lines flip together in horizontal, vertical, and diagonal directions.

Choose from three local opponent styles. Entry focuses on immediate captures, Steady favors safer edges and available moves, and Advanced searches deeper while weighing corners and the endgame. These are rule-based strategies; no guaranteed result is promised.

Explore 30 corner challenges built from playable positions, learn the rules in a three-part tutorial, and review completed matches move by move. Match review includes a score progression, turning points, and corner control. During a solo match, undo one recent round. Same-device matches keep undo disabled for fair play.

An unfinished position, preferences, local results, streaks, and completed puzzles stay on your device. Play does not require an account or an internet connection.
