Medium Sudoku
The sweet spot — enough challenge to make you think, never so much that you stall.
★ Solved
Brilliant!
Medium Sudoku tightens the screws. With 32 to 36 given numbers, scanning alone will not carry you to the end; you will start keeping pencil marks and spotting subtler deductions.
What a medium puzzle demands
Expect to lean on hidden singles — a digit that can only go in one cell of a row, column or box even though that cell has other candidates — and the occasional naked pair to trim possibilities. Keeping notes turns a medium grid from frustrating to flowing.
Who medium Sudoku is for
Solvers who breeze through easy and want a real but fair fight. It is the best level for practising notes before tackling hard and expert grids.
Frequently asked questions
Do I need pencil marks for medium Sudoku?
They help a lot. Medium grids often hide singles and pairs that are far easier to see with notes.
