About 9x9 Queens Puzzles

A 9x9 Queens puzzle features a 9x9 grid divided into 9 colored regions. Your goal is to place exactly 9queens on the grid — one in each row, one in each column, and one in each color region. No two queens can be adjacent, including diagonally.

Large grids require advanced solving techniques like region confinement, adjacency chaining, and systematic elimination. These puzzles can take several minutes even for experienced solvers.
