Monster Sudoku

Alastair Chisholm

Book cover: Monster Sudoku

If you’re finding Sudoku a bit tame these days, then “Monster Sudoku” is the answer. “Monster Sudoku” contains the numbers 1-9 but also the letters A-F, creating a monster 15X15 square.

The 201 puzzles in this book range from delicious, through pernicious, malicious and finally the eye-wateringly hard vicious Monster Sudoku. They are designed to perplex and frustrate you, to obsess you and, finally, to alienate you from your friends, family and pets. Good luck!
