Othello (Reversi) is a pupular board game. With this program, you can play against your PV (which is quite hard, if you are not experienced) or with your friend, using PV as a board. You can even watch your computer fighting with itself. In the new version, position can be saved to postpone the game.
Rules of the game
The game of Othello is played on an 8x8 board using discs that are black on one side and white on the other side. The game starts with four discs in the center squares of the board, two black discs on diagonally adjacent squares, and two white discs on the other diagonally adjacent squares. Players alternate placing an additional disc, with black moving first. A move consists of "outflanking" one or more of your opponent's discs. Outflanking means placing a disc so that at least one row of your opponent's discs is bordered by a disc of your color, including the disc just placed on the board. A row is defined as one or more discs of a single color in a continuous straight horizontal, vertical, or diagonal line. When a player moves, the row or rows of outflanked discs are flipped over showing his or her color. If a player cannot outflank a disc, the turn is forfeited and the opponent takes another turn. The game is over when the board is filled or neither player can move. The player with the most discs showing is the winner.
