Description
120 medium Sudoku puzzles where pencil marks and pairs start to pay off.
Fill the grid so every row, every column and every 3 × 3 box holds the numbers 1 to 9 exactly once. Each puzzle has one solution, and it can be found by logic alone.
Every puzzle in Medium Sudoku is rated Medium, which means it needs singles plus naked pairs and pointing pairs, so pencil marks start to pay off. This is where most people find Sudoku most satisfying: the grid opens up once you spot a pair or a pointing pair, and the puzzles take fifteen to thirty minutes.

Stuck? Play it in Ninebloom
These puzzles were made and checked by Ninebloom, our Sudoku app for Android, and rated the same way: by the techniques a puzzle needs, not by how many numbers are missing. Every classic puzzle in the books has a small QR code beside it; scan it and the same puzzle opens in the app, where a hint names the technique that cracks the next square and shows you why. Get Ninebloom on Google Play (free, no account needed) or read more at ninebloom.leafyorb.com.
