Sudoku - Brain Games No Ads

Classic Sudoku, made calm. No ads, no accounts, no tracking — just you and the grid. Every puzzle comes from a graded puzzle bank, so Easy really is easy and Expert really makes you think. Play a new daily puzzle with everyone else, or pick a level and play as many as you like — and learn the techniques that solve the hard ones.

Go back and play the days before FOUR LEVELS OF CHALLENGE • Easy, Medium, Hard and Expert • Tell the app how well you know Sudoku and start at the right level • Each harder level opens as you solve puzzles at the one before it • Pick up right where you left off — every game is saved, finished or not • Pause any time to resume, restart, start a new game or change settings LEARN TO SOLVE • Step-by-step lessons on solving techniques, shown on a real board • From the last empty cell to X-Wings and colouring chains PLAY IT YOUR WAY Choose how much help you get, from Beginner to Advanced. Expert, and setting every option yourself, open once you reach the Expert level: • Notes, with notes filled and cleared for you if you like • Undo, hints and an eraser • Mistakes shown as you write them — or a limit of one to five for a real challenge • Highlights for the same digit and the row, column and box you are in • Remaining count for every digit on the number pad • A timer you can show, hide or pause MAKE IT YOURS • Light, dark or follow your phone • Eleven accent colours, with an app icon that matches • Five fonts and three text sizes • A colour-blind friendly mode that marks mistakes with a ring, not just red THOUGHTFUL DETAILS • Keep the screen on while you play • Haptic feedback • Favourites and a full history of every game — swipe a game to favourite, end or delete it • Available in English, Deutsch, Français, Italiano, Suomi and Türkçe PRIVATE BY DESIGN Your games and settings stay on your device.
