How to play
Each row, column and region (shaded area) should have exactly one Queen (♛).
Additionally, no two queens should neighbour each other, not even diagonally.
Click on a cell to place an ×. Click again to place a Queen. Click on a Queen to remove it.
Click "Check Solution" to validate your solution. You can also click "Generate new Board" to start over with a new board.
To accelerate the gameplay, you can toggle the "use × markers" option to directly place queens with one click.
By default, the engine will only supply riddles that have at least one solution. To increase the difficulty, you can deactivate "Only play solvable riddles". This will increase the point value of solved riddles.
