How to Play Queens: Rules of the Queens Logic Puzzle

The rules of the Queens puzzle (also known as Star Battle) explained simply: one crown per row, column and region, and crowns never touch.

The rules

1. Place exactly one crown in every row.
2. Place exactly one crown in every column.
3. Place exactly one crown in every colored region.
4. Crowns may not touch each other, not even diagonally.

On an N×N board there are N rows, N columns and N regions, so a solved board always has exactly N crowns. A good puzzle has exactly one solution and can be solved with logic alone, without guessing.

Queens is a version of the classic Star Battle puzzle with one star per line. It became popular as a quick daily game; in some apps crowns are drawn as queens, in Crownly they are golden crowns.

How to start

1. Look for the smallest region or a region squeezed into one row or column.
2. Mark cells that can't hold a crown with a dot (tap once in Crownly). Dots are as important as crowns.
3. Every time you place a crown, dot its row, column, region and the eight cells around it.
4. When you get stuck, look for a region whose open cells all sit in one line.
