This game uses the same rules as othello and is similar to reversi. Each player takes turns to place down a disc in an empty position, where at least one opponent's disc can be captured and flipped over. An opponent's disc can be captured if it is in between the newly placed disc and another disc of the same color. This can be horizontally, vertically and diagonally. When a player can't make any valid moves, they skip their turn. The winner is the player who has the most discs flipped over to their color, at the end of the game. The circle in the bottom left corner indicates which player is currently making their move.
