The goal of Reversi (also called Othello) is to fill the board with as many discs of your color as possible. Use your mouse to place colored discs on the board. You may place a disc anywhere on the board, as long as it surrounds at least one of your opponent's discs on opposite sides. You can surround discs horizontally, vertically, or diagonally. After you place your disc, any discs that you surrounded will flip over to your color. At the end of the game, if you have more discs 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 (medium), and 3 star (hard) buttons. If you need help, click the options button and turn on the flip number hint. It will help you see your possible moves and work on your strategy!
REVERSI TIPS & TRICKS
Conquer the corners. The corner spots on the board are the places to be. Discs in the four corners can't be flipped and open up more ways to flank your opponent's discs. On the other hand, you’ll want to keep your pieces away from any of the three spots surrounding the corners. Landing a piece there will make it easy for your opponent to take the corner and steal the advantage.
Look to the future. When deciding where to move, take a look at the available spots on the board. You’ll have to calculate the risks and rewards with every move. Think ahead a few steps on your turn. When building your strategy, think about the placement of your discs and whether or not your opponent will take your pieces on their next turn.
Don’t rush. Try to limit the amount of pieces you have on the board at the start of the game. While your goal is to take more spaces than your opponent, you don’t need to be the winning player right away. The less pieces you have on the board, the less of a chance your opponent has to steal them.
Don’t trap yourself! Leave plenty of space open for you to continue making moves with your color. If you run out of spaces to place your piece, you'll lose a turn. You can come back into the game if your opponent gives you an opening to do so. Alternatively, look for chances to trap your opponent so that they can’t flank any of your discs. If you successfully stall them, you can easily win the game!
WHAT YOU LEARN FROM PLAYING REVERSI
Reversi is very much a game of strategy. Playing with a friend or against the computer helps strengthen spatial reasoning skills, since players have to look in multiple directions when planning their moves.
Cover the board with your color in the classic disk-flipping game. Tap a square to place a disk on the board. Surround your opponent's disks to flip them to your color.
