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 Master. Every puzzle is generated with exactly one solution.
- Pencil marks. Note candidates by hand, and the app clears the ones that no longer fit as you place numbers.
- Mistake checking you control. Have errors flagged the moment you make them, or switch the checking off entirely.
- Unlimited undo. Step back through the whole solve, as far as you need.
- Hints when you are stuck. A hint fills in a square for you, so you can carry on instead of giving up.
- 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.
- Highlighting built for clarity, with strong contrast between the row, column and box you are working in.
- Built for one hand, phone and tablet, with the controls where your thumb already is.
What it costs
Sudoku is free to download and free to play. It is funded by rewarded video advertisements, and those only ever play when you choose to watch one, for example to get an extra hint or to carry on after the mistake limit. No banners, no interstitials, and nothing that interrupts you mid-puzzle.
Puzzlemore Premium is optional. It removes the advertising, gives unlimited hints, lifts the mistake limit, unlocks every past daily puzzle and lets you start battles. Available monthly or yearly; your store shows the price in your own currency before you confirm.
There is no energy system, no lives to wait for and nothing that stops you playing.
Common questions
Do I need an internet connection?
Solo puzzles are generated on your device and play fully offline. Battles, advertisements and purchases need a connection.
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 we will look into it.
Will ads interrupt my game?
No. The only advertisements are rewarded videos, and one plays only after you tap a button offering it. There are no banners and no full-screen ads between puzzles.
Can I turn off personalised advertising?
Yes. In the EU, the UK and Switzerland you are asked before the first advertisement, and you can change that choice at any time in the app’s settings. Decline and you still see advertisements, but they are not based on your activity. See the privacy policy.
I bought Premium but the ads came back.
Use Restore purchases in Settings. Premium is tied to the App Store or Google account you bought it with, so make sure you are signed in with that account.
