About Queens Puzzle Online
A logic puzzle to play in your browser: a new board every day, plus practice at five sizes.
What it is
Queens Puzzle Online asks you to place one queen per row, column and region without any two touching. It runs on phones and computers, with nothing to install.
How the puzzles are made
A generator built into the site lays out a legal set of queens, grows the regions around them, and then uses a solver to confirm the board has exactly one solution. Boards that fail are discarded.
The Daily is created from the calendar date, which sets both its size and its layout, so a date always gives the same board. A new one arrives at midnight on your device. Practice boards are created at random when you ask.
Free, with no account
The game is free to play and there is nothing to sign up for.
Where your results live
Saved boards, streaks and best times are stored in your browser on your device. Clearing the browser's site data erases them, and they do not carry over to other devices. The privacy page explains more.
Credits
The boards come from the site's own code, so there is no outside puzzle collection or data source to credit.
