Puzzlemore
The classic 9×9, done properly.
Five difficulty levels from Easy to Expert, an endless supply of puzzles generated on your device and a board built to stay readable whether you are on a phone on the train or a tablet on the sofa.
Built for people who actually solve
Most Sudoku apps bury the puzzle under banners, popups and currencies. This one does not. You get the grid, the numbers, and the tools a solver actually reaches for.
- Five difficulty levels. Easy, Medium, Hard, Expert and Evil. Every puzzle has exactly one solution and is solvable by logic alone. No guessing required, ever.
- Pencil marks. Note candidates by hand, or let the app fill and clean them up for you as you place numbers.
- Mistake checking, your way. Flag errors the moment you make them, only when you ask, or not at all.
- Unlimited undo. Step back through the whole solve, as far as you need.
- Hints that teach. A hint names the technique it used, so the next puzzle gets easier rather than the current one getting shorter.
- Auto-save. Close the app mid-puzzle and it is waiting for you exactly as you left it.
Readable, always
The board scales to your screen instead of shrinking to fit a fixed layout. Numbers stay large, the 3×3 boxes stay distinct, and everything you tap is big enough to hit first time.
- Real dark mode. Not a grey filter, but a palette designed separately for dark screens.
- Adjustable text size that follows your system setting.
- Colour-blind friendly highlighting that never relies on colour alone to tell you something.
- Landscape and portrait, phone and tablet, with the controls where your thumb already is.
What it costs
Sudoku is free to play in full. Every difficulty level is available without paying, and the free version shows advertisements between puzzles.
Puzzlemore Premium is a single subscription, priced at less than a cup of coffee a month, that removes the advertising and unlocks the premium features in Sudoku and in every other Puzzlemore app. One subscription, all our games. You can cancel at any time from your App Store or Google Play settings, and there is no energy system and nothing that stops you playing either way.
Common questions
Do I need an internet connection?
No. Puzzles are generated on your device, so the game works fully offline. A connection is only used to load advertisements in the free version.
Do I need to create an account?
No. There is no registration, no login and no email address to hand over. Your progress and statistics are stored on your device.
Can a puzzle have more than one solution?
No. Every puzzle is verified to have exactly one solution before it is shown to you. If you ever find one that does not, please tell us and include the puzzle ID from the pause menu and we will look into it.
I have Puzzlemore Premium but the ads came back.
Use Restore purchases in Settings. Your subscription is tied to your App Store or Google Play account, so it follows you to a new device and to every other Puzzlemore app as long as you sign in with the same account. If it still does not appear, contact support.
How do I turn off personalised advertising?
Open Settings → Privacy inside the app to change your advertising consent at any time. On iOS you can also revoke tracking permission in the system Settings; on Android you can reset or delete your advertising ID. See the privacy policy for detail.
