Queens

About Queens

Place one queen on each row, column, and colored region of the grid so that no two queens share a row, column, or diagonal. Each puzzle presents a board divided into distinct colored areas; every area must contain exactly one queen, and the same applies to every row and column. The challenge comes from overlapping constraints: a cell that satisfies a row requirement may violate a diagonal or a region.

The timer adds pressure, but the real test is logical deduction. As boards grow larger and regions become more irregular, you must think several steps ahead. A common mistake is placing a queen that later forces an impossible situation in another part of the board, so careful planning beats speed. The game rewards methodical scanning of rows, columns, and color clusters.

Tips to win

• Begin by scanning rows, columns, and colored regions that have the fewest available cells; these often force a queen's position.
• Use X marks to rule out cells that are attacked by an already placed queen; this narrows possibilities quickly.
• When stuck, focus on one color region: because each region must contain exactly one queen, eliminating all but one cell in that region solves it.
