A queens game you can play right here, free — with no daily limit. This is Queens Logic, an original GameOLL logic game. The board is split into coloured regions. Your job is to place one queen in every row, every column and every region, and no two queens may touch, not even diagonally. Every puzzle has exactly one solution, proven by a solver before it joins the bank. No download. No sign-up. It works on your phone and your PC.
Some puzzle apps give you one board a day and ask you to come back tomorrow. Here the puzzles are unlimited. Finish one and the next is one tap away. A shared Daily Puzzle is here too, for the days when you want the same board as everyone else — but it is a bonus, never a gate.

How to play Queens Logic
The board is a square grid cut into coloured regions. On the Easy board there are 8 regions on an 8 by 8 grid. On the Hard board there are 10 regions on a 10 by 10 grid. Hidden inside the colours is one — and only one — way to place all the queens.
- Pick a board — 8 x 8 Easy or 10 x 10 Hard — and press Play. A fresh puzzle appears, and the clock starts.
- Tap a square once to mark it with an X. The X means "no queen can live here". It is your pencil. Use it for every square the rules rule out.
- Tap the same square again to place a queen. Tap a third time to clear the square and start it over.
- Queens that break a rule glow red at once: two in one row, one column or one region, or two touching side by side or corner to corner. Red means think again — the game never lets a wrong board look finished.
- Stuck? Tap Check and the game removes every queen that is not part of the solution, and tells you how many were wrong. You get 3 checks per puzzle, so spend them when a board feels close but will not close.
- Truly walled in? Tap Hint. The game locks one true queen onto the board with a gold frame, and clears away any of your pieces that clash with it. You get 3 hints per puzzle.
- Place the last queen with no red glow anywhere and the puzzle is solved. Your time is saved, and your win streak grows.
Checks and hints never solve the puzzle for you. A check only removes queens that are wrong. A hint places a single queen. The thinking in between is all yours, which is exactly why finishing feels good.
The rules of Queens Logic
Four rules run the whole game. Every row holds exactly one queen. Every column holds exactly one queen. Every colour region holds exactly one queen. And no two queens may touch — not side by side, not above or below, and not even at the corners, diagonally.
The touch rule is the quiet killer. In most grid puzzles, two answers can sit corner to corner in peace. Here they cannot. A queen poisons all eight squares around it, and that one fact solves more of the board than any other. When you place a queen, cross out its whole neighbourhood before you do anything else.
One promise sits under every board: each puzzle has exactly one solution. The bank was built by construction and proof — first a set of queens was placed so it obeys every rule, then regions were grown around those queens, and then a solver counted the solutions and kept only the puzzles with exactly one. So the answer is always there, logic alone can always find it, and you never have to guess.
Controls for phone and PC
| Action | Phone / tablet | PC / laptop |
|---|---|---|
| Mark an X | Tap a square once | Click a square once |
| Place a queen | Tap the square again | Click the square again |
| Clear a square | Tap the square a third time | Click the square a third time |
| Check your queens | Tap Check | Click Check, or press C |
| Use a hint | Tap Hint | Click Hint, or press H |
| Pause the clock | Tap Pause | Click Pause, or press P |
Pausing hides the board. That is fair play: nobody can study the regions while the clock is stopped, and nobody can peek at your screen either.
The two boards and your records
The two boards differ in size, and size changes everything. More rows means more regions, longer chains of logic, and far more squares for a queen to poison.
| Board | Grid | Regions | Best for |
|---|---|---|---|
| Easy | 8 by 8 | 8 | Learning the rules and quick daily solves |
| Hard | 10 by 10 | 10 | Long chains of logic and a real fight |
The Daily Puzzle is one shared Easy board built from the date itself, so every player in the world gets the same regions on the same day. Finish it and your daily streak grows. But the daily is a spice, not the meal: normal play is unlimited on both boards, all day, every day.
Your records live in your browser. The game keeps puzzles played and won on each board, your best time on each board, your day-by-day win streak, and your daily streak. Nothing is uploaded and no account is needed. Come back tomorrow and your streak is still waiting.
7 solving tips that actually work
- Start with the smallest region. A region with only two or three squares leaves very few homes for its queen. Rule out what its neighbours force, and small regions often solve themselves first.
- Cross out the whole neighbourhood. The moment a queen lands, mark an X on all eight squares around it, plus every other square in its row, its column and its region. Half of good solving is honest bookkeeping.
- Hunt the forced square. Scan each row, column and region for one with a single open square left. That square must hold the queen. Place it, cross out its fallout, and scan again — solves come in chains.
- Watch the corners of regions. If a region reaches into a row in just one square, and that row already has its queen elsewhere, the whole region must place its queen outside that row. Narrow reach means narrow choices.
- Think in pairs. If two regions together touch only the same two rows, those two rows are spoken for — every other region can be crossed out of them. Pairs and triples quietly unlock crowded boards.
- Never guess a queen. A guessed queen that happens to fit can still be wrong, and it poisons every deduction built on it. X marks are free and safe; queens should be earned by proof.
- Spend checks late, hints later. A check is worth most when the board is nearly full and one wrong queen blocks the finish. A hint is worth most when two full minutes of scanning find no forced square at all.
Is Queens Logic free and safe to play?
Yes. The game is free. It runs fully inside this page. It asks for no name, no email and no account. It installs nothing on your device. Your records and streaks stay in your browser only.
Queens Logic is an original game made by GameOLL. The rules are the classic region-queens rules: one queen per row, column and region, and no touching. The puzzles were generated and proven on a solver before the game was published, so the bank on this page is fixed, fair and always ready.

Queens Logic FAQ
Is Queens Logic free to play?
Yes. Queens Logic is 100% free. You play it right on this page. There is no download, no sign-up and no payment.
How many puzzles can I play each day?
As many as you like. Puzzles are unlimited on both boards. Some puzzle apps allow one queens puzzle a day, but here a fresh board is always one tap away. The Daily Puzzle is an extra shared board, not a limit.
Does every puzzle have exactly one solution?
Yes. Each puzzle was built around a set of queens that obeys every rule, regions were grown around those queens, and a solver then counted the solutions. Only puzzles with exactly one solution were kept, so logic alone can always finish the board.
What does the Check button do?
Check looks at every queen you have placed. Any queen that is not part of the one true solution is removed, and the game tells you how many were wrong. You get 3 checks per puzzle. X marks are never checked or removed.
Can I play Queens Logic on my phone?
Yes. The board is built for touch. Tap a square once for an X, again for a queen, and again to clear it. It also works with a mouse and a keyboard on laptops and desktop PCs.
Does the game save my progress?
Yes, in your own browser. It keeps your puzzles played and won on each board, your best time on each board, your win streak and your daily streak. Nothing leaves your device.
Final verdict: should you play Queens Logic?
Yes — if you like logic puzzles that respect your time and your brain. Queens Logic gives you a fair board every time: one true solution, honest checks and hints that help without playing for you, records that wait in your browser, and no daily cap standing between you and the next puzzle. The Easy board teaches the rules in minutes. The Hard board can hold you for half an hour. Pick a board, and start crossing out squares.
