Queens Game Rules

This page describes the exact rules of Queens Game: how queens are placed, what the colored regions mean, which placements count as a conflict, and how a level is completed. New to the game? Start with the beginner guide.

Core Queens Game Rules

The board is an N×N grid divided into N colored regions.
You must place exactly one queen in every region.
Every row must contain exactly one queen.
Every column must contain exactly one queen.
No two queens may touch each other diagonally.
A level has a single valid solution that satisfies all rules at once.

Queen Placement Rules

Tap an empty cell to place a queen and tap it again to remove it. Queens go only on open cells — squares marked with an X are blocked and can never hold a queen. You are free to rearrange queens at any time until every rule below is satisfied.

Rows and Columns

Think of rows and columns like a chessboard. A queen claims its entire row and its entire column, so a second queen can never share that row or column. Because the board is N×N with N queens, the solution always places one queen on every row and one on every column.

Board Regions

Each colored area is a region, and there are exactly as many regions as there are rows and columns. The region rule adds the real challenge: even if a square is legal by row and column, it is only valid if its region does not already contain a queen. Solving the puzzle means lining up the row, column, and region constraints together.

Queen Conflicts

A conflict is any placement that breaks a rule: two queens in the same row, two in the same column, two in the same region, or two on diagonally adjacent cells. The diagonal rule is limited — only the four touching corners around a queen are off-limits, not the full diagonal line. Conflicts are highlighted instantly so you can undo and adjust.

How to Complete a Puzzle

The level is finished the moment every region, row, and column holds exactly one queen with no diagonal touches remaining. There is no timer pressure to worry about — accuracy is all that matters, and a correct board ends the level automatically.

Rule Examples

Valid: two queens on the same diagonal but several cells apart — diagonals only block neighboring corners.
Invalid: two queens placed corner-to-corner — that is a diagonal conflict.
Invalid: two queens inside the same colored region, even on different rows.
