Classic N-Queens: origin & explanation
The classic N-Queens problem places N queens on an N×N board so that no two share a row, column, or diagonal. This page adds color regions and a ‘no touching (including diagonal adjacency)’ rule to increase challenge and strategic depth. It is the same puzzle popularized as the daily Queens game on LinkedIn.

Frequently Asked Questions
Have another question? Let us know.
What does the X mark mean?
X marks a cell where a queen cannot be placed. You can add X by clicking or dragging; with auto-mark on, placing a queen will generate X around it, in the same row/column and color region.
Why color regions?
Color regions add another constraint: besides one per row and column, each color region must also contain exactly one queen.
How do I win?
You win when every row, column, and color region has exactly one queen and no two queens are diagonally adjacent.
Can I undo or reset?
Yes. Use ‘Undo’ to revert the last action, and ‘Reset’ to clear the board and start over.
What is conflict highlighting?
When enabled, queens involved in row/column/region conflicts or diagonal adjacency are highlighted to help you locate and fix issues quickly.
Is this the same as the LinkedIn Queens game?
Yes — the rules are identical: place exactly one queen in each row, column, and color region, with no two queens touching (including diagonally). This is a free browser version with unlimited levels and hints, so you can practice beyond the daily puzzle.
