A free queens logic puzzle on a colored board. Place one queen per row, per column, and per region — and never let two touch. New boards forever, no sign-up.
Tap a cell to place a queen, tap again for an ✕ marker, tap once more to clear.
Boards are generated around a hidden valid placement, with regions grown outward from those queens, so every deal can be solved. Like deduction grids? The Hashi Bridges page is the same kind of slow, satisfying logic.
A logic placement puzzle. Place exactly one queen in every row, column, and colored region, and never let two queens touch — even diagonally.
Tap once for a queen, tap again for an ✕ marker on a cell you have ruled out, and tap a third time to clear. Queens that break a rule glow red.
Only touching matters. Two queens simply may not sit in adjacent cells in any direction. Queens two or more cells apart are fine.
Yes. Each board is grown around a valid hidden queen placement, so at least one solution always exists.
Yes. The whole game is tap-based and runs in any mobile browser with nothing to install.
