Crowns (Star Battle Puzzle)

How to play

The grid is split into colored regions, one per row. Place exactly one crown in every row, every column and every color region. Crowns may never touch each other, not even diagonally. Tap a cell once to mark it with ✕ (a reminder that no crown can go there), tap again to place a crown, and a third time to clear it. Drag across cells to mark many ✕ at once. Every board is generated with exactly one solution, and it can always be found by logic alone — no guessing needed. Play as many boards as you like, from 6×6 up to 10×10: a fresh puzzle is generated every time, and after each solve you can jump straight into the next one. Each size has its own leaderboard for the fastest solve times.

Tips

• Start with the smallest region: its crown has the fewest possible spots.
• If a region sits entirely inside one row or column, no other region can use that row or column — mark the rest with ✕.
• Before placing a crown, check whether it would wipe out every free cell of a neighbouring region. If so, that cell is a ✕.
• Turn on Auto ✕ to see every cell a crown rules out at a glance.
• Each size has its own leaderboard ranked by time, so take a breath, then go fast — wrong crowns turn red right away.
