How to solve a Queens puzzle
Place one queen in every row, every column, and every colored region, with no two queens touching — not even diagonally. Tap a cell once to mark an X where a queen cannot go, tap again to place a queen, and tap a third time to clear it. Swipe to mark several cells at once, and placing a queen auto-marks the cells it rules out. New to the game? Read the full how to play guide.
Unlimited mode generates a fresh board every time, so it never runs out — practice at any of the eight sizes above, then apply what you learn to the daily challenge or a timed Beat the Clock run. For the deductions behind every solve, see the solving techniques guide.
Frequently asked questions
Is Queens Unlimited free to play?
Yes. Queens Unlimited is free in your browser — no login, no download, and no paywall. Generate as many boards as you want at any size on this page.
What grid sizes can I play in Unlimited?
Every size from 5×5 to 12×12. Use the size tabs on this page to switch; each N×N board is split into N colored regions and takes N queens.
How is Unlimited different from the daily challenge?
The daily challenge is three shared boards (8×8, 9×9, and 10×10) that stay the same for everyone until the next UTC midnight. Unlimited hands you a fresh, uniquely solvable board on demand at any size from 5×5 to 12×12, and you can press New puzzle for another whenever you like.
How does seed sharing work?
Every Unlimited board is generated from a seed. The share link includes that seed, so anyone who opens it gets the exact same grid you were playing — same size, same regions, same unique solution.
Do I need an account to play Unlimited?
No. You can play, generate new boards, and share by seed without signing in. An account is optional and is not required for Unlimited.
