Russian Draughts Duel

The traditional and most popular type of checkers in Russia and the countries of the former USSR. The goal of the game is to deprive the opponent of the opportunity to move by taking or locking all his checkers. The game can be played with artificial intelligence, together with another person on the same device, or with a rival online in multiplayer mode. You can also watch other players' games, act as a spectator, and offer your own version of the player's next move by making it on the board. The player with the white checkers goes first. A simple checker moves diagonally forward one square. The queen moves diagonally to any available field, both forward and backward. Taking is mandatory. A simple checker located next to the opponent's checker, behind which there is an empty field, is transferred through this checker to this free field. If it is possible to continue taking other opponent's checkers, then this capture continues. Taking a simple checker is done both forward and backward. The queen hits diagonally, both forward and backward, and stands on any free field after the beaten checkers. The game is considered won: - if one of the opponents has beaten all the checkers; - if one of the opponents' checkers and queens are immobilized, i.e. he is unable to make a move when it is his turn;
