Medium Sudoku (Free Printable PDF)
A medium sudoku strikes the classic balance: enough starting digits to keep things fair, but few enough that you will need a sharper eye and a few real deductions. This free generator creates a fresh nine-by-nine puzzle each time, always with a single guaranteed solution, so every step can be reasoned out without guessing. Work through the rows, columns, and boxes, watch for the squares where only one digit can possibly fit, and build steadily from there. It is the everyday sweet spot for regular solvers, challenging enough to satisfy but never so hard it stalls. Solve it in your browser, or download a tidy, printable PDF complete with the answer key.
