What you can play
Each day brings three Sudoku puzzles (easy, medium and hard), two nonograms (10 × 10 and 15 × 15) and one Minesweeper board. Everyone gets the same puzzles on the same date.
| Game | Puzzles per day | What is guaranteed |
|---|---|---|
| Sudoku | 3: easy, medium, hard | Exactly one solution; the level says which techniques are needed |
| Nonogram | 2: 10 × 10 and 15 × 15 | Solvable by looking at one row or column at a time |
| Minesweeper | 1: 9 columns, 12 rows, 20 mines | A safe first move and no situation that needs a guess |
The puzzles use digits, cells and flags, not words, so they read the same in any language.
How a day works
- Open a game. It shows the puzzle for today, by the date of your device.
- Play. Every move is saved in your browser, so you can close the page and continue later.
- When a puzzle is solved, the page shows your time and today counts for your streak.
- Tomorrow the next puzzles open. Earlier days stay available in the archive.
A puzzle opens on its own date and not before. The site never links to a later day.
How the streak is counted
A day counts when you solve at least one of that day’s six puzzles on the same date. The current streak is the number of such days in a row, ending today, or ending yesterday while today is still open.
Example: you solve a puzzle on Monday, Tuesday and Wednesday. On Thursday morning the panel shows a current streak of 3 days. Solve any of Thursday’s puzzles and it becomes 4. If you skip Thursday, the panel shows 0 on Friday, and the best streak stays at 3.
Puzzles from the archive that you solve on a later day are saved as solved, but they do not extend a streak.
How the puzzles are made and checked
The puzzles are produced by our own generator programs before the site is published. Each puzzle comes from a seed made of the game, the variant and the date, so the same date always gives the same puzzle.
A puzzle is published only after a solver program has confirmed the guarantee in the table above. Every published puzzle is checked again each time the site is built; one failing puzzle stops the build.
Common mistakes
- Expecting the same progress on another device. Progress is stored in one browser and is not synchronised.
- Playing in a private window. Most browsers delete stored data when the private window closes, and the streak goes with it.
- Changing the date of the device to open a later puzzle. The streak is counted by the same date, so it becomes unreliable.
Frequently asked questions
- Do I need an account?
- No. The site has no accounts and no sign-up. Progress, streak and settings are stored in your browser.
- When does the next puzzle open?
- At midnight by the clock of your device. The site uses your local date, not a fixed time zone.
- Can I play puzzles from earlier days?
- Yes. The archive lists every day from the first puzzle up to today. Archive puzzles save progress like the puzzles of today.
- Why did my streak disappear?
- The streak lives in the storage of your browser. It is lost when the site data is cleared, when a private window closes, or when you use another browser or device.
- Is there a leaderboard?
- No. A leaderboard would need accounts and a server that stores results. The site does not store your results on a server.
