Queens rules: how to play the online logic puzzle

Queens is a strategic logic puzzle inspired by the classic N-Queens problem. Your task is to place queens on a board so they never attack one another, using careful planning to conquer each level.

Goal of the game

Every level presents a unique grid. You must place the required number of queens so that no two pieces share the same row, column, or diagonal. Later stages introduce unusual board shapes, blocked cells, and special layouts that demand creative thinking.

Some puzzles may already contain fixed queens or obstacles. You must work around them to build a valid arrangement that satisfies the level objective.

Basic rules

1. The board is divided into cells similar to a chessboard.
2. You place queens on empty cells to attempt a solution.
3. Queens attack across rows, columns, and diagonals without distance limits.
4. A level is solved only when no two queens attack each other.
5. Some stages include blocked cells or pre-placed queens that cannot be moved.
