How do I play Queens on this site?

Tap a cell to place X, tap X again to place a queen, and tap queen again to clear the cell. The cell state cycle is: empty → X mark → queen -> empty. Conflicting placements are highlighted so you can fix them. When a queen is placed, it automatically crosses out the empty cells in its row, column, and region with a faint X. Use Reset to clear the board and start over.

If a row, column, or region already has a queen, every other cell in that group is blocked. Look for regions that force a queen into only one possible row or column. Look for cells which can not contain a queen due to the rules.
