Buying guide
Sudoku books vary far more than they look: in how the levels are set, in whether every puzzle can be solved by logic, and in how comfortable the grids are to work on. This guide covers all three, then shows the printable sudoku book we make.

There is no single standard for sudoku difficulty. Our levels are set by how many numbers, called givens, are filled in at the start. Fewer givens means more deduction before the grid opens up.
| Level | Puzzles | Givens | What it feels like |
|---|---|---|---|
| Beginner | 15 | 40 | Plenty of easy openings |
| Easy | 15 | 34 | A few moments of thought |
| Medium | 15 | 30 | Pencil marks start to help |
| Hard | 15 | 26 | Patient, step-by-step logic |
A real sudoku never needs a guess. If a grid has two possible solutions, you reach a point where logic cannot decide between them, which spoils the puzzle. Our generator solves every puzzle and throws away any with more than one solution, so logic alone always gets you to the end.
Pocket sudoku books are easy to carry but leave tiny cells with no room for notes. Large sudoku books are comfortable but bulky. A printable book sidesteps the choice: print one puzzle per sheet at full size, fold it into a pocket, and leave the rest at home.
Our sudoku book is an instant download, so there is no searching shops or waiting for delivery. Buy it, print the first puzzle, and start in minutes.
Every puzzle in our packs is generated and then checked by computer before it is allowed into a pack. Anything that fails a check is thrown away and replaced.
