Hyper Sudoku 3D Challenge 1 Paperback – October 12, 2013

A different way of doing these puzzles... really like this one... gotta keep the mind working...

It was more than I expected. Really like it. Wish their more of them. Gave copies to family and friends.

I am totally addicted to these puzzles. Am on my 3rd book.

Great Puzzle

Challenging to the utmost.
