Othello, also known as Reversi, is a classic board game that is famous for its simple rules and intense competition. The objective of the game is to flip your opponent's pieces on the board and maximize your own piece count. Othello can be played in a two-player mode or against an AI opponent, with the AI difficulty available in three levels.

The game board of Othello is an 8x8 grid, and the pieces come in two colors, black and white. Players take turns placing their pieces on empty squares, with the requirement that a straight line (horizontal, vertical, or diagonal) must exist between the newly placed piece and another existing piece of the player's color, sandwiching one or more of the opponent's pieces. The sandwiched opponent's pieces are then flipped to the player's color. If a player cannot make a legal move, they must pass their turn until a valid move becomes available or the board becomes filled.

With its straightforward rules and intricate tactics, Othello appeals to players of all ages. It offers a thoughtful and strategic gaming experience, where players need to consider the potential consequences of each move in order to seize more board space.

In addition to the traditional two-player mode, Othello also provides an option to play against AI opponents. The AI difficulty is divided into three levels: beginner, intermediate, and advanced. Players can choose the challenge level that suits their skill level. The beginner difficulty is generally suitable for newcomers, the intermediate level offers a moderate challenge, and the advanced level provides a real test for experienced players.
