How to play Crowns
Place one crown in every row, every column and every coloured region.
These are the rules for the PlayBurst version. Other versions may play differently.
Rules and controls
1. Place a crown
Tap a square once to rule it out, again to put a crown on it, and a third time to clear it. Ruling squares out is how the puzzle is solved; the crowns are what finish it.
2. One of each
Every row, every column and every coloured region ends up holding exactly one crown, and no more.
3. Never touching
No two crowns may sit next to each other, including corner to corner on a diagonal.
4. Read the heavy lines
The thick edges mark where one region ends and the next begins, so the regions can be read without relying on their colours.
