About this game

Sudoku the way it should be. No ads, no trackers, no interruptions.

PLAY WITHOUT AN ACCOUNT
Open the app and start playing. Unlimited puzzles, every difficulty, every theme, and your stats and history kept on your device. No sign up, no timer, no banner ads, and nothing asking you to watch a video to continue.

EASY TO EXPERT
Four difficulty levels, from a relaxed Easy through to Expert. Every puzzle has exactly one solution, so it is always solvable by logic and never by guessing.

PLAY IT YOUR WAY
Tap a number, press and hold, or drag to fill. Auto pencil marks and a smart number pad keep the bookkeeping out of your way. Conflict highlighting shows clashes as you go, and deferred mistake marking lets you find your own errors instead of being interrupted the moment you slip.

A NEW PUZZLE EVERY DAY
The Daily Challenge is the same puzzle for everyone, with streak tracking and leaderboards where only genuine first attempts count.

MAKE IT YOURS
Plenty of themes to choose from, including dark mode, paper, sepia and a few playful ones. Adjustable grid and colours, plus a colourblind friendly high contrast mode with larger numbers and screen reader support.

SIGN IN FOR THE ONLINE EXTRAS
Signing in adds leaderboards, the Daily Challenge, cloud history, and sync across your devices so you can start on your phone and finish on your tablet. These are included for your first 14 days.

ONE TIME PAYMENTS. NO SUBSCRIPTIONS.
Playing without an account carries no charge and no limit. If you want the online extras after your first 14 days, you can buy access for 30 days, 180 days or a year. Every purchase is a one time payment. Nothing auto renews, nothing bills you again, and there is nothing to cancel. When your time runs out you simply decide whether to buy more.

PRIVACY
No ads, no ad networks, no advertising ID, and no third party analytics or tracking SDKs. We collect only what runs the app: your sign in details, your game progress for sync, and an anonymous usage beacon you can switch off in Settings. We do not sell your data or share it with advertisers.

What’s new

Added
• Android visitors on the web app now see a quiet banner pointing to Google Play. It only shows in a browser, never inside the app itself, and can be dismissed for good.
