Basic Rule

The game allows up to four players to play at the same time. Each player takes turns to place a queen on the chessboard.

No two queens are allowed on the same row, same column, or same diagonal.

The player who cannot place a queen on the chessboard anymore loses the game.

Team Mode

If the Team Mode is on, queens placed by the same player will be on the same team and will not kill each other.
