Frequently asked questions
Is easy Sudoku suitable for beginners?
Yes. Easy puzzles are designed for practising the rules, scanning and certain placements without needing advanced patterns.
Should I use notes in easy Sudoku?
Use them when a cell still has several possible digits. Notes make your reasoning visible and are better than a guess.
How do I find my first certain digit?
Start with rows, columns or boxes that have only a few gaps. Compare the missing digits with one empty cell; if only one remains, the move is certain.
Explore Naked SingleWhat should I do when no cell is certain?
Move to another unit and scan again. You can note the possible candidates, but do not place a digit while more than one option remains.
When am I ready for medium Sudoku?
Medium is the right next step once you solve easy puzzles without guessing and can use candidate notes with confidence.
