Reversi (or Othello) is a game in which the goal is to get the more discs on the board at the end of the game.

- Players alternate turns as long as they can make a move and the game ends when neither player can make a move.
- A disc can only be placed where it will flip opponent discs. Discs are flipped whenever they are caught in between an already existing disc and a new disc that has been placed.
