The Goal
To solve a Queens puzzle, you must place exactly one Queen in every row, column, and colored region on the board.
The Rules
Exactly One per Row/Col
Each queen must be the only one in its row and column. Multiple queens in the same line are not allowed.
One Queen per Color
The board is divided into irregular colored regions. Each separate color must contain exactly one queen.
No Touching
Queens cannot be placed in adjacent cells, including diagonals. They need their own personal space!
