About this project

The LinkedIn Queens puzzle is a variant of the classic N‑Queens problem. Each row, column, and color must contain exactly one queen and no two queens can occupy the same 2×2 block. The puzzle is solved as a constraint‑satisfaction problem using constraint propagation to prune possibilities and find a valid solution.
