About Royal Grid

Royal Grid is a calm logic puzzle where every board has exactly one solution and can be solved by pure logic, no guessing. Place one crown in every row, every column and every color region, without letting any two crowns touch, not even diagonally. Start with tiny 5x5 boards and climb level by level up to 9x9 master puzzles. Stuck? The hint button doesn't just show the answer, it explains why a cell must be a crown. Works on desktop and mobile, available in English and Korean.

How to play Royal Grid

Tap or click a cell to place a crown, tap it again to remove it. Cells ruled out by your crowns are dotted automatically. Fill every row, column and color region with exactly one crown, and keep crowns from touching (including diagonally). Use the hint button if you get stuck.
