Queens Game

One queen in every row, column and color — and no two queens may touch.

How to Play Queens: the Four Rules

The queens game looks like sudoku's fiercer cousin: an N×N grid split into N colored regions, and you must place exactly N queens so that:

One queen per row. Every row holds exactly one queen — no more, no fewer.
One queen per column. Every column also holds exactly one.
One queen per color. Each colored region contains exactly one queen.
No touching diagonally. Two queens may never sit on diagonally adjacent squares — queens can be in neighboring rows or columns, just not diagonally next to each other.

Tap a square to place a queen, tap it again to remove it. The moment two of your queens break a rule — same row, column, color or diagonal touch — both light up red, so wrong ideas surface instantly. The puzzle is solved when every constraint holds at once.

Daily Queens Puzzle: Same Board for Everyone

Every day at midnight UTC there's a fresh daily queens puzzle, and it's the identical board for every player in the world — no account, no app, nothing to sign up for. Your 🔥 streak and progress live in your own browser: solve the daily on consecutive days and the streak counter climbs. When you solve it, share your result — the share text says you solved, never where your queens went, so no spoilers for friends who haven't played yet. It joins the rest of the HanoiStack dailies, from Futoshiki to Picross, as a two-minute morning ritual.

Queens Strategies: Where to Place Your First Queen

Start with the smallest or strangest region. A region squeezed into a corner has precious few legal squares, so its queen is the most constrained — place it (or at least narrow it down) first.
Corners and single-cell corridors are free information. If a region touches the board edge in only one or two squares, those squares are strong candidates.
Use eliminations, not guesses. Every queen you place crosses out its whole row, column and color. Before committing, ask which remaining regions have only one square left uncrossed — that's a forced placement.
Watch the diagonal ban. The touching rule bites when two regions meet diagonally: two queens on diagonally adjacent squares of different colors still break the rules.

Queens vs Star Battle vs LinkedIn Queens

All three are "region placement" logic puzzles, but the rules differ. Star Battle (published by Ships) asks for two or three stars per row and region on bigger grids — longer and stricter. LinkedIn Queens popularized the one-queen-per-color format but locks streaks and hints behind a login. This version keeps the friendly rules — one queen per row, column and color, no diagonal touching — and stays free and open: play without an account, keep your streak locally, and practice on 7×7, 8×8 or 9×9 boards whenever you like.

Play Free Queens Puzzles by Grid Size

Practice mode gives you unlimited boards in three tiers. 7×7 is the gentle warm-up — seven regions, small enough to reason about in a minute or two. 8×8 is the classic daily size, where elimination chains start to matter. 9×9 is for the patient: more colors, more interactions, and more chances for one early mistake to cascade. Stuck at any size? The hint button reveals one correct queen — use it sparingly if you want to keep the solve honest.

Frequently Asked Questions

Is this queens game really free?

Yes — every board, the daily puzzle, hints and streaks are all free, with no ads mid-game and no account anywhere.

Do I need a LinkedIn account to play?

No. This is the no-login queens game: your streak and progress are stored locally in your own browser, and nothing is uploaded anywhere.

How often is there a new puzzle?

A new daily board at midnight UTC, every day — plus unlimited random practice boards in three grid sizes whenever you want more.

What if two queens touch diagonally?

That's a rule break: both queens flash red until you move one of them. Queens in neighboring rows or columns are fine — only diagonal touching is banned.

Does the difficulty scale?

It does. The daily rotates through 7×7, 8×8 and 9×9 boards, and practice mode lets you pick a size — bigger grids mean more regions and longer elimination chains.
