Othello, also known as Reversi, is a strategy board game for two players, played on an 8×8 uncheckered board.
- The game starts with two black and two white pieces placed in the center of the board.
- Players take turns placing one piece of their color on a square such that at least one opponent's piece is captured between the new piece and an existing piece of your color.
- All captured pieces are flipped to the current player's color.
- If a player cannot make a valid move, their turn is passed.
- The game ends when the board is full or when neither player can make a valid move.
- The player with the most pieces on the board at the end wins.
