One of the varieties of the game of checkers, a characteristic feature of which, unlike most variants of checkers, is that the moves and captures of checkers are made not diagonally, but vertically and horizontally.

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.

Rules:

- The player with the white checkers goes first.
- A simple checker moves one square forward, left, right.
- The queen moves to any number of empty fields forward, backward, right, left.
- If a player has the opportunity to take the opponent's checkers during his turn, he must take them. Taking an opponent's checker is possible only when the field behind the opponent's checker is free. If the checkers that beat the opponent's checker can be hit further from the new position, the capture of the checkers continues further. You can beat several of your opponent's checkers in one move.
- If there are several options for taking the opponent's checkers, the player must choose the one with the largest number. This applies to taking both checkers and queens.
- If there are several options for taking the same number of checkers, the player has the right to choose any of these options.
- A simple checker hits the opponent's checker, standing in front, on the right or on the left. Taking back the opponent's checkers or queens is prohibited.
- The queen takes the opponent's checkers from her through any number of empty squares in front, back, right and left, if the field next to the checker is empty. A queen, like a simple checker, can beat several of the opponent's checkers in one move. Having beaten the opponent's checker, the queen is obliged to stand on the field behind the broken checker.
- Checkers are removed from the board one by one during the battle, but the queen does not have the right to reverse its direction during a vertical or horizontal stroke, that is, by 180°.
- A simple checker that enters the eighth horizontal line becomes a queen at the end of the turn, but it cannot continue to strike as a queen on the same turn.
- The winner is the one who was able to destroy all the opponent's checkers or deprive them of the possibility of a move, or the one who was left with several of his simple checkers against one simple opponent's checkers.
- If the players have one piece left on the board, a draw is declared.
