The whole point
No ads. Not before you pay, not after.
Most free Sudoku apps pay for themselves with ads. Banners between puzzles, full-screen interstitials, watch a video to earn a hint. Best Sudoku has none of it. No ads, no pop-ups, no tracking, ever. We keep the lights on with a simple one-time unlock instead of selling your attention.
Built with care
Craft in every detail
A proven logical solve path
Every puzzle can be solved by logic alone, with no guessing. Before a puzzle ships, the engine solves it the way a person would, one technique at a time, and keeps only the puzzles that pass.
Difficulty that means something
Your difficulty setting maps to the hardest technique a puzzle actually needs. Easy leans on simple singles. Expert calls for advanced moves like X-Wings. Fewer clues at random never counts as harder.
A new challenge every day
One Daily Challenge for everyone, with streaks and leaderboards that only count genuine first attempts.
Themes and a clean board
Twelve themes, adjustable grid and colors, a distraction-free clean mode, and full accessibility support.
Play anywhere, synced
Play online or offline. Your games and stats sync across devices, so you can start on your phone and finish on your laptop.
Unlock once, no subscription
A 14-day free trial with everything unlocked. After that, keep playing free with a puzzle a day, or unlock full access once. No subscription, no auto-renew, and no ads either way.

How to install on iPhoneCommon questions
- Is it really free to start?
- Yes. Every new account gets a 14-day free trial with everything unlocked, no card. The first 50 beta players get two extra months of full access free on top. After the trial you can keep playing for free with one puzzle a day, or unlock full access with a one-time payment. No subscription either way.
- Is it really ad-free?
- Completely. No banners, no interstitials, no watch-an-ad hints, before or after you unlock.
- Do you track me?
- No. There is no ad tracking and no third-party analytics. Your game stays yours.
- Do I need an account?
- No account is needed to start playing. Sign in only if you want your games and stats to sync, or to claim the beta offer.
- What devices does it work on?
- Any modern browser. It installs as an app on iPhone and Android straight from the browser. A Google Play release is imminent and an App Store version is on the way.
- Are the puzzles always solvable?
- Always. Every puzzle has one unique solution and can be solved by logic alone, so you never have to guess.
- How do the leaderboards stay fair?
- Only genuine first attempts count, and scores are checked on our servers, so restart-farming does not make the board.
