How to Play
Master Sudoku is about building skill puzzle by puzzle. Fill the 9×9 grid so every row, column and 3×3 block contains 1 to 9 once, and aim to solve each one a little faster than the last.
If the technique is unfamiliar, spend a minute with our step-by-step guide before you dive in. The more grids you clear, the more the patterns start to jump out on their own.
Tips & Tricks
- Solve the fixed, obvious cells first so the board opens up for the tougher deductions.
- Keep an eye on the clock only after you are confident of a move, not before.
- Repeated practice trains your eye to spot the same patterns quickly across new puzzles.
Frequently Asked Questions
Does Master Sudoku get harder as I go?
It offers puzzles across a range of difficulty, so you can start gently and take on tougher grids as your confidence grows.
Is finishing quickly the goal?
Speed is a nice bonus, but an accurate, logically sound solve matters more than a fast one.
