Reversi Othello, Duel for PC

The game uses a square board measuring 8 by 8 cells and 64 special chips, painted white and black on different sides. One player plays white, the other - black. When making a move, a player places a chip on a cell of the board of "his" color. At the beginning of the game, 4 chips are placed in the center of the board: two black and two white. The first move is made by black. Then the players move in turns.

The game can be played with artificial intelligence, with another person on one device, or with an opponent online in multiplayer mode.

When making a move, a player must place his piece on one of the squares of the board in such a way that between this piece and one of the pieces of his color already on the board there is an unbroken row of the opponent's pieces, horizontal, vertical or diagonal (in other words, so that the unbroken row of the opponent's pieces is "closed" by the player's pieces on both sides). All the opponent's pieces that are part of the row "closed" on this move are turned over to the other side (change color) and go to the player who made the move.
If as a result of one move more than one row of the opponent's pieces is "closed" at the same time, then all the pieces that are on those "closed" rows that go from the piece that was placed are turned over.
A player has the right to choose any of the moves possible for him. If a player has possible moves, he cannot refuse to make a move. If a player does not have possible moves, then the move is passed to the opponent.
The game ends when all the pieces are placed on the board or when neither player can make a move. At the end of the game, the chips of each color are counted, and the player with the most chips on the board is declared the winner. In the event of a tie, the game is considered a draw.
