About Crowns
Crowns is a placement puzzle on a board split into regions. Put exactly one crown in every row, every column and every region, and never let two crowns touch, not even diagonally. Boards grow from 6×6 on easy days to 8×8 on hard days, and each has exactly one solution.
How to play Crowns
- Place exactly one crown in every row, every column and every region.
- Two crowns may never touch, not even at the corners.
- Tap a square once to mark it ×, again for a crown, and a third time to clear it.
- Every board has exactly one solution and can be solved by logic. Fastest time wins.
Tips & strategy
- Start with the smallest region: it has the fewest places a crown can go.
- When a region lies entirely within one row or column, no other region can use that line.
- Every crown rules out the eight squares around it, so mark them with × straight away.
- If two regions are confined to the same two rows, the other regions cannot use those rows.
- Look for a row where every open square belongs to the same region; that region’s crown must be in that row.
Crowns: questions and answers
Can crowns touch at the corners?
No. Two crowns may never be next to each other in any direction, including diagonally.
How do I mark squares?
Tap once for ×, twice for a crown and a third time to clear the square.
Are the regions shown only by colour?
No. Each region also has its own pattern and a thick border, so the board can be read without colour.
How is Crowns ranked?
By time. The fastest correct solve wins.
Where should I start?
With the smallest regions: a region of one square must hold a crown. Then look for any region whose open squares all lie in one row or column; that line’s crown is in that region, so the rest of the line can be marked ×.
