What Crownquill does
Crownquill gives you a grid split into colored regions. Place exactly one crown in every row, every column and every region, and never let two crowns touch, not even corner to corner.
A new puzzle comes every day, the same for every player. Mondays are gentle, and the puzzles get harder toward the weekend. Every puzzle has one answer you can reach by logic alone. It plays offline in English, German, French and Spanish, needs no account, and is free with ads.
