Doubolo

Doubolo is a board game variant inspired by Reversi (also known as Othello). The objective is to have the majority of your color pieces on the board by the end of the game.

Players take turns placing colored squares on a 23 × 14 grid. Each move must sandwiched opponent pieces between your own, flipping them to your color—horizontally, vertically, or diagonally. Some squares on the grid are unusable (marked as blocked), creating unique board layouts each game. A coin flip decides who starts, and play continues until no valid moves remain. The player with the most pieces on the board wins.
