Sudoku — Brain Games, No Ads

Classic Sudoku, made calm. No ads, no accounts, no tracking — just you and the grid.

A new puzzle every day

One daily puzzle, the same for every player. Missed a day? Go back and play the days before.

Four levels of challenge

Easy, Medium, Hard and Expert — every puzzle comes from a graded puzzle bank, so Easy really is easy and Expert really makes you think. Every game is saved, finished or not, so you can pick up right where you left off.

Play it your way

Choose how much help you get, from Beginner to Expert, or set every option yourself:

• Notes, filled and cleared for you if you like
• Undo, hints and an eraser
• Mistakes shown as you write them — or a limit of three for a real challenge
• Highlights for the same digit and the row, column and box you are in
• A remaining count for every digit, and 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
