Why this level?
A medium Sudoku gives around 30–34 clues, so plain scanning gets you part of the way and then you reach for pencil marks (candidate notes). It is the level most daily solvers enjoy.
How to print
Click "Download book", open the PDF and pick A4 or US Letter. Six puzzles print per page; the matching answers live in the separate solutions PDF.
Solving tips
When scanning stalls, pencil in the candidates for each empty cell and look for cells with a single candidate, or numbers that fit only one spot in a box.
Frequently asked questions
What makes a Sudoku medium difficulty?
Fewer starting clues than an easy grid, so you will usually need candidate notes — but no expert chains.
Will I need to use pencil marks (candidates)?
Usually yes. When scanning stalls, note the possible numbers in each empty cell and look for cells with a single candidate.
How many clues does a medium Sudoku start with?
Around 30–34 given numbers — enough to start by scanning, but you will finish with candidate notes.
