Crown Logic
Solve queens-style logic puzzles by placing one crown in every row, column, and color region without letting crowns touch.
About Crown Logic
Crown Logic is a queens-style region puzzle. Place crowns on a colored grid so every row, column, and region has exactly one crown, with no crowns touching each other.
How to Play
Tap a cell to place a crown, switch to mark mode to rule out cells, and use Check when you want conflicts highlighted. A board is solved when each row, column, and color region contains one crown and none of the crowns touch, even diagonally.
Tips & Strategies
- Start with tiny color regions because they have fewer candidate cells.
- If a row already has a crown, mark the rest of that row as impossible.
- Use diagonal adjacency to eliminate cells around every placed crown.
- Look for columns that are forced by region placement.
- Switch between crowns and marks often to keep the board readable.
