Murderous Maths: Su doku

100 fun number puzzles.

Before you read this page, you must answer YES to both the following questions:
Do you like PRIME NUMBERS?
Do you like sudoku puzzles?
If you’re sure your answers are YES and YES, then read on. If you’re not sure then we suggest you go and play the Bridges Game instead. It’s logical like sudoku, but it doesn’t hurt your head so much.
Sudokus are the HOLY GRAIL of puzzles. They are very small, the instructions are very simple, but just like the puzzles in our own sudoku book, they can vary from Dead Simple up to Devious, Drastic and even DIABOLICAL!
