Monster Sudoku

by Alastair Chisholm

Sudoku has taken over the world. The simple 9X9 puzzle has spread everywhere to become the most unexpected and spectacular success, but 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!
