Puzzle game · Android
Place one crown in every row, every column and every color region, and keep the crowns from touching, even at a corner. Every board has exactly one answer, and you can always reach it without guessing.








Tap a cell once for an X and twice for a crown. You can drag across cells to cross out a whole stretch at once, and Auto X quietly dots every cell a crown rules out, so you spend your time on the thinking and not the bookkeeping.
If you play the daily queens game in your feed, it's the same kind of puzzle, without waiting until tomorrow for the next one. Want to try it before you install anything? The Queens puzzle page runs on the same engine, right in your browser.
Warm up starts at 5x5, then Easy 6x6, Medium 8x8, Hard 9x9, Expert 10x10 and Master 11x11. I ran every board through a solver to make sure it has one answer and that logic alone gets you there. Nothing is locked, so you can jump straight to the big ones.
Everyone gets the same board on the same date. It starts at 6x6 on Monday and grows to 10x10 by Sunday, and it works offline too.
A hint highlights the cells that matter and gives the reason in one sentence, like "This region has one free cell left". You tap Apply once it makes sense to you.
A broken rule shows a soft red stripe and one plain sentence, and you fix it when you're ready. The timer stays hidden unless you switch it on.
Daylight is a warm cream board with pastel regions. Velvet is a dark board with deep jewel colors, and it turns on by itself in dark mode. Color blind patterns give every region its own texture, so you never depend on color alone.
Yes. It's free to download and supported by ads. Hints come after a short optional video, and if no video loads you still get the hint. A full screen ad may show after some solved boards, never while you're solving one. One purchase removes the ads and makes every hint free.
No. Every pack and the daily board work offline, and there's no account or sign in.
A 6x6 board takes a minute or two. An 11x11 one can keep you busy for a good while.
