Medium Sudoku: Online Puzzles To Level Up Your Skills

Ready to move beyond the basics? Our medium sudoku collection bridges the gap between easy and hard, offering fair challenges that reward careful reasoning. These puzzles are ideal if you want to practice stronger logic, reduce reliance on singles, and build momentum toward advanced play.

Who This Level Is For

Medium sudoku is great for players who are comfortable with the fundamentals and want to grow. These games take more attention because they start with fewer givens: almost always 21 to 23, against 30 at Easy. If you routinely finish easy puzzles and understand notes and basic scanning, this is the right next step.

What To Expect

• Fewer obvious singles and more reliance on candidate notes
• Steady use of elimination in rows, columns, and boxes
• In about one puzzle in three, one step beyond singles, such as a pointing pair or a naked pair

Techniques You Will Use More Often

Medium games can be solved without guessing. Keep using basic solving techniques like Last Possible Number and Last Remaining Cell: singles alone finish 974 of our 1,521 medium puzzles (64%). The rest need one more idea, such as a pointing pair, a claiming group or a naked pair. Every medium puzzle has a Sudoku Explainer rating of 3.0 or less.
