"Royal Grid" Game

Royal Grid is a peaceful logic puzzle where every board has exactly one solution — and you can crack it with pure thinking, no guessing needed! Your mission: place one crown in every row, every column and every color region, while making sure no two crowns touch — not even diagonally. Begin with tiny 5x5 boards and climb level by level all the way up to giant 9x9 master puzzles. Stuck? The hint button doesn't just reveal the answer — it explains why a cell must hold a crown. Play on desktop or mobile, in English or Korean.
