What makes a good puzzle
A Queensguard puzzle is its regions: one crown goes in every row, column and color region, and no two crowns touch. Paint all 64 cells into eight connected regions, one per color.
Every Coronet puzzle is fair: it has exactly one solution, and you can reach it by logic alone, without guessing. Test checks both. Most hand-painted boards have many solutions at first; small, awkward regions are what pin the crowns down. The link only holds your regions, never the answer, so your friend can’t peek.
