Queens

How to play

Place 6 queens on a 6×6 colored grid so that no two are in the same row, column, color region, or diagonally adjacent.

Click a cell to cycle through: empty → X (marked as "no queen") → queen → empty. Conflicts are shown with red diagonal stripes. The game auto-finishes when 6 queens are placed with no conflicts. "Reveal wrong" gives you a +30s hint.

No timer, no scoring. This is just to learn.
