About Constelly
A daily dot-to-dot puzzle where the stars tell you how to connect them.
Every day at midnight (UTC) a new puzzle appears: a sky full of numbered stars. Connect them with straight lines and a hidden picture lights up — an animal, a plant or an everyday object. Everyone gets the same puzzle on the same day. It's free, there's no sign-up, and it works in any modern browser on your phone, tablet or computer.
How to play
The number on each star is how many lines touch it in the finished picture. It isn't an order to follow — you decide which stars to join, and the numbers tell you whether you're right.
- Draw a line: tap one star, then another. Keep tapping to carry on from the last star, which is handy for outlines; tap that star again (or empty sky) to stop. You can also drag from one star to another.
- Watch the numbers count down. A star shows how many lines it still needs. When it reaches zero it lights up: yellow if all of its lines are right, red if one of them is wrong.
- Fix mistakes with the eraser (tap it, then tap a line), undo your last move, or start over. A star can never take more lines than its number.
- Read the clue. The quote at the top of the screen hints at the picture without giving it away.
- Stuck? A hint draws one correct line for you. It stays locked in place.
The puzzle is solved when every star is yellow — then the whole picture lights up and its name is revealed.
A tiny example
Scoring, streaks and sharing
Your result is your time and the number of hints you used — wrong lines along the way don't count against you. The timer starts with your first line and pauses whenever you switch away from the page.
Solve the puzzle on its own day to keep your streak going. Statistics show how many you've solved, your current and best streak, and your average time and hints. The Share button copies a spoiler-free summary (puzzle number, time, hints and a star rating — never the picture) with a link to the same puzzle, to send to friends. Three stars means no hints, two means one or two hints, and one star means three or more.
Past puzzles and replays
Missed a day? Open the menu and choose Past puzzles to play any earlier puzzle. Past puzzles are just for fun: they're marked as solved in the list but don't change your streak or statistics. Any puzzle you've solved can be played again with Play again; your first solve stays the one that counts.
Questions
When does the new puzzle come out?
At 00:00 UTC every day — that's 01:00 or 02:00 in Denmark and most of Europe, and the afternoon or
evening before in the Americas. The countdown after you solve a puzzle shows exactly how long is left.
Do I need an account?
No. Your progress, streak and statistics are saved in your browser on this device. They don't
move between devices, and clearing your browser's site data resets them.
Why did a star turn red?
It has as many lines as its number, but at least one of them is wrong. Erase or undo lines
touching it until it turns yellow — or leave it and come back when the picture takes shape.
Is there an app?
Constelly is a website, so there's nothing to install — but you can add it to your home screen.
On iPhone, tap Share, then Add to Home Screen; on Android, open the browser menu and
choose Add to Home screen or Install app.
Is it free?
Yes. Constelly is paid for by ads; see the privacy page for how
they and your data are handled.
