Who is easy Sudoku for?
Levels are based on the solving techniques required: naked singles, hidden singles, candidate eliminations, and finally hidden pairs or X-Wing. New puzzles are checked against these levels and can be solved without guessing.
The techniques you need
Two basic techniques are enough on the easy level. A Naked Single is a cell where only one number remains possible. A Hidden Single is a number that fits only one spot within a row, column or box. Once you spot these two patterns reliably, you can solve any easy Sudoku.
How to progress
When easy puzzles start to feel too quick, move up to Medium. There you get fewer given numbers and begin to work with pencil marks. The step up feels natural once you can solve an easy grid without guessing.
Frequently asked questions
What is the best way to start as a beginner?
Start with an easy Sudoku. Focus first on rows, columns and 3x3 boxes that already contain many digits, because those usually reveal the next safe move fastest.
What should I do if I get stuck?
Move to another area of the grid and compare row, column and box again. It also helps to use notes for candidates instead of guessing.
How do the difficulty levels differ?
Levels are based on the solving techniques required: naked singles, hidden singles, candidate eliminations, and finally hidden pairs or X-Wing. New puzzles are checked against these levels and can be solved without guessing.
