World’s Hardest Killer Sudoku, vol 3

A new volume of World’s Hardest Killer Sudoku has just been published. Nothing’s changed from previous 2 volumes: 90 IQ Killer Sudokus and 10 INSANE Killer Sudoku puzzles in this book. Well, of course, all puzzles are NEW, not published before.

This book is certainly now for beginners. It is only for experienced Killer Sudoku solvers.

Are you up for this challenge?

    Just got my copy of the latest book ‘World’s Hardest Killer Sudoku Volume 3″! Could not wait to start working on it tonight! It’s about time! Used to be that every Christmas there is one of these ‘hardest’, ‘deadliest’ killer sudoku books that came out right before Xmas, great stocking stuffers/ presents! I understand there probably is not that great a market for the most challenging games and it is nice that more people can enjoy puzzles at every level; still I am thrilled to see my appetite for these puzzles whet and met.
    By the way is there another ‘puzzles of children’ book on the horizon? I gave my 6 and half year grandson a copy 2 years ago for Christmas and he loved working on them, sometimes with my participation. Great bonding experience
