Place one crown in every row, column, and colored region. Crowns may never touch — not even diagonally. Mark impossible cells with ✕ as you deduce.
📖How to Play
The grid is divided into irregular colored regions. Place crowns so that each row, each column, and each region contains exactly one crown. No two crowns may touch — including diagonally (king-move adjacency).
Tap cells to cycle empty → ✕ → crown. Use ✕ marks to note cells that cannot hold a crown.
🎮Gameplay Mechanics
1. One Per Row and Column
- Exactly one crown in every row.
2. One Per Region
- Each colored region must contain exactly one crown.
- Region shapes are irregular — read the borders carefully.
3. No Touching
- Crowns may not share an edge or a corner.
- If two crowns are within one king-move of each other, both are invalid.
4. Marks (✕)
- Cycle a cell to ✕ when you know it cannot hold a crown.
- Marks are optional aids and do not affect the win check.
5. Win Condition
- Place exactly n crowns on an n×n board.
- No conflicts on rows, columns, regions, or adjacency.
💡Tips for Success
1. Start With Small Regions
- Tiny regions force a crown into a short list of cells.
2. Cross Off Crowded Rows
- After placing a crown, ✕ the rest of that row and column.
3. Watch Diagonals
- A crown blocks all eight neighboring cells — not just the orthogonal ones.
4. Use Check
- Highlight conflicts anytime you’re unsure whether two crowns clash.
