Chapaev's Checkers

"Chapaev's Checkers" is a Soviet board game, named after the name of the participant of the Civil War Vasily Ivanovich Chapaev.
Unlike most checkers games, there is no need to think about moves and calculate the opponent's steps. Dexterity is important here. This game is more like billiards than checkers-chess.
The goal of the game is to knock out all the opponent's checkers from the board by clicking, trying to keep at least one of his own on it. Whose checkers are left on the board is the winner!
