Crown Me: Logic Grid

Place crowns on a board of coloured regions. Every row, every column and every colour gets exactly one crown, and no two crowns may touch, not even diagonally. Three simple rules, and a puzzle that asks for pure logic. NEVER A GUESS Every board has exactly one solution, and you can always reach it by reasoning. The generator checks each puzzle with a deduction solver and throws away anything that would need luck. Tap once to mark an X where a crown can't go, tap twice for a crown, or drag to mark many cells at once. HINTS THAT TEACH Stuck? A hint doesn't just reveal a cell. It names the rule that cracks the board, like "This colour fits in one row only", and lights up the cells that prove it. Play a while and you'll spot the patterns yourself: last free spots, colours trapped in a row, crowns that would block a whole region, and pairs of colours that own two rows. TWO CROWNS IN EXPERT Expert puts two crowns in every row, column and colour on boards up to ten by ten. The deductions run much deeper, and some need one careful step of "what if". THREE WAYS TO PLAY Relax: small boards that introduce one idea at a time. Hard: eight and nine wide boards that need sharper logic. Expert: two crowns per line on the biggest boards. STARS FOR CLEAN LOGIC One star for solving, two for solving without a hint, three for solving without a hint and without ever placing a wrong crown. Your solve time is shown, but there is no time limit. HELP WHEN YOU WANT IT Auto-X marks every cell your crowns already rule out. Check circles any wrong marks. Hint shows the next deduction. Clashing crowns glow red and the game tells you which rule they break. ADS AND THE ONE PURCHASE The game is free. After your first few wins, a short ad may play between puzzles, at most every third one and never in the middle of a board. Hints and Check are optional rewarded ads that you choose to watch. The one purchase, Remove Ads, switches off the ads between puzzles for good; the optional rewarded helps stay available. No account, no sign-up, plays offline. Your progress stays on your device.
