Queens Game basics
How to Play Queens Game
These Queens puzzle instructions are simple: place one queen in every row, column, and colored region. The only extra constraint is that queens cannot touch diagonally.
Four constraints
The rules stay simple
One Queen Per Row
Every horizontal row must contain exactly one queen.
One Queen Per Column
Every vertical column must contain exactly one queen.
One Queen Per Region
Each colored region must contain exactly one queen.
No Diagonal Touching
Queens cannot touch each other diagonally.
Legal and illegal placements
These diagrams are rule fragments, not complete puzzles. Check all four constraints on your actual board.
One per row and column
IllegalTwo queens in the same row conflict, even when far apart.
One per region
IllegalTwo queens in one colored region conflict even in different rows and columns.
No touching corners
IllegalR1C1 and R2C2 are diagonally adjacent: this placement is illegal.
Distant diagonals are allowed
Allowed by the spacing ruleR1C1 and R3C3 do not touch. A long chess diagonal is not a Queens rule; their regions must still differ.
Controls on phone and desktop
Start the board before placing queens. Tap or click a cell to cycle its mark; double-click or double-tap to place a queen directly. Use Undo to reverse a move, and Check to review the board. Your unfinished board stays in this browser; signing in does not promise cross-device restoration of those local marks.

Your first board
A good first solve
Do not try to guess a full solution at once. Work from the most constrained line or region, then let each queen reduce the next set of candidates.
- 1Scan for a single safe cell
Look for a row, column, or region with only one plausible queen position.
- 2Use X marks to protect the board
Once a queen is placed, rule out its row, column, and touching diagonals.
- 3Check the new pressure
Revisit nearby regions after every placement. A new restriction often creates the next move.
Stay accurate
Common mistakes to avoid
- Counting an X as a move. X marks are only notes; every completed board still needs one queen in each constraint group.
- Checking rows and columns without checking the colored region that contains the square.
- Thinking queens attack along full diagonals. In Queens Game, they only cannot touch corner to corner.
