The game has game variants that differ in:

- board size: 7, 9, 11, 13

- victory conditions: bring the king to the edge or corner of the board.

- king encirclement conditions: from two or four sides.

- the number of attacking (black) and defending (white) pieces.

You can play the game with artificial intelligence, with another person on one device, or with an opponent online in multiplayer mode.

The attacking black pieces move first. Then the players move in turns. All pieces move vertically or horizontally to any number of free cells, like a rook in chess. Pieces cannot jump over each other, stand up or pass through the central and corner "fortresses", which can only be occupied by the king's piece.

Pieces are captured by pincers with two enemy pieces on their turn. Pieces do not move diagonally or pinch. It is possible to capture an enemy piece between your own piece and an empty "throne". The "throne" is always hostile to attackers, but only to defenders when it is empty. Capture is not mandatory. Cut pieces leave the board forever.

For the white pieces to win, the king from the center of the "Throne" must reach:

- in a game with a "fortress" symbol in the corners - one of these corners.

- in a game with a highlighted edge of the board - just this edge.

To win, the black pieces must capture the king by surrounding him.
