Solve our medium sudoku collection Set 2. Test your skills.
Medium 6x6 Sudoku puzzles have fewer starting numbers than easy puzzles, requiring you to use more advanced solving techniques. This helps you develop stronger logical reasoning skills.
Look for opportunities to eliminate possibilities and use techniques like scanning and marking candidates. Pay close attention to the interactions between rows, columns, and boxes.

At medium difficulty, 6x6 puzzles require students to use elimination more deliberately. When a row has four of six numbers filled, the remaining two cells can only contain the two missing numbers. Determining which goes where requires checking both the column and the box constraints — a three-way intersection check that is the fundamental operation of all sudoku solving.
Best for logic warmups, classroom puzzle stations, independent solving, and gradual technique practice.
Answer support is available for review after a real attempt; printable answer-key behavior depends on the activity type.
