Reversi

Reversi Instructions
Reversi is a strategy board game played on an 8x8 grid, where the objective is to have the majority of pieces in your color by the end of the game. The game begins with four pieces placed in the center of the board: two black and two white, arranged in a diagonal pattern. Players take turns placing pieces of their color on the board, with the aim of capturing their opponent's pieces. To capture, a piece must be placed so that it flanks one or more of the opponent's pieces in a straight line-horizontally, vertically, or diagonally-with another piece of the same color. When this happens, all the flanked pieces are flipped to the player's color. A move is only valid if it results in at least one piece being flipped, and if no valid moves are available, the player must pass their turn. The game ends when neither player can make a move, and the winner is the player with the most pieces of their color on the board.
