The goal of Reversi, also known as Othello, is to fill the board with as many disks of your color. Use your mouse to place colored disks on the board. You may place a disk anywhere on the board, as long as it surrounds a group of your opponent's disks on opposite sides. You can surround disks horizontally, vertically, or diagonally. After you place your disk, any disks that you surrounded will flip over to your color. At the end of the game, if you have more disks of your color than your opponent, you win!
If the computer opponent is too hard or too easy, you can set the difficulty level of a new game with the 1 star (easy), 2 star, and 3 star (hard) buttons. If you need help, click the options button (it looks like a gear) and turn on the flip number hint. It will help you see your possible moves and work on your strategy!
