Learn Queens in four moves

Queens is a logic puzzle about exclusion. Place one queen in every row, column, and colored region while keeping queens from touching each other.

Practice on 7x7
1. One queen in each row

Start by finding a row where only one cell can work. A solved board has exactly one queen across every row.

Rows

Every horizontal row gets exactly one queen.

Columns

Every vertical column gets exactly one queen.

Regions

Every colored area gets exactly one queen.

Touching

Queens cannot share an edge or diagonal corner.

Mastering Queens Game: Strategies & Advanced Logic

Whether you call it Queens, Star Battle, or logic grids, mastering this puzzle requires more than just guessing. By applying deductive logic, you can solve even the hardest 12x12 boards without making a single mistake.

1. The "Hidden Single" Technique

The easiest way to start any Queens puzzle is to look for tiny regions. If a colored region only has one or two cells, it's highly restricted. Placing an 'X' in any cell that belongs to a tiny region can often reveal the only possible square for that region's queen. This is called a "Hidden Single".

2. Region Intersection

As you progress to Classic (8x8) and Advanced (9x9) puzzles, you will encounter regions that stretch across the board. If all the remaining empty cells of a specific color fall entirely within a single row or column, you can safely place an 'X' in all other cells of that row or column, because the queen for that region must occupy that line.

3. The "Diagonal Wall" Defense

Because queens cannot touch diagonally, placing a queen automatically places an 'X' on all 8 surrounding cells. Use this to your advantage to split large regions in half. If a region looks like a snake, placing a queen near its middle can often cut off access to the rest of the shape.

4. Counting Regions (The Star Battle Method)

Queens Game is essentially a variation of the famous "Star Battle" logic puzzle, but with exactly one star per region instead of two. If you look at two rows together, they must contain exactly two queens. If a large region completely engulfs those two rows, it can only hold one queen, which means the second queen must be squeezed into the remaining empty spaces. Recognizing these shape constraints is the secret to solving Master (12x12) grids.
