Queens answer. #924
Queen positions
Rows and columns below start at 1, from the top left.
- Row 1: column 1.
- Row 2: column 6.
- Row 3: column 4.
- Row 4: column 2.
- Row 5: column 5.
- Row 6: column 3.
- Row 7: column 7.
Why it works
The official placement has one queen in every row, column, and coloured region, with no queens touching.
