Othello

Othello (also known as Reversi) is played on an 8×8 board. You play as Black and go first; the computer plays White.

Placing a disc: Click on a highlighted square to place your disc. You can only place on squares that outflank at least one of the opponent's discs – meaning your new disc and an existing disc of yours form a straight line (horizontal, vertical, or diagonal) with one or more opponent discs in between. All outflanked discs are flipped to your color.

Passing: If you have no legal moves, your turn is automatically skipped. If neither player can move, the game ends.

Winning: The game ends when neither player can move (usually when the board is full). The player with the most discs wins.

Tips: Corners are extremely valuable – once placed, they can never be flipped. Be cautious about playing next to an empty corner, as it may give your opponent access to it.

Use the Undo button to take back moves. Change difficulty at any time (takes effect on the next AI move).
