Crownplot

How it plays

1. Place one crown in every row, every column and every coloured region. Crowns never touch, not even diagonally.
2. Tap a square for an X (no crown here), again for a crown. Every puzzle has one solution and is solved by logic alone.
3. A new daily puzzle every day, plus 3,630 practice puzzles from 5×5 to 11×11. Undo is always free.
