Best of the best and really NASTY hard. I love the series 1 thru 4.
Not only hard but the paper is supreme and space for 'working'
I love the spiral for flat working No complaints, only joy. You will
love these things.
I have worked every SUDOKU author - even the Igloo series from Australia.
This MENSA SERIES is the #1 BEST!!!! I haven't made it past Level 1 yet
but I'm working a couple pages each nite & my cognitive reasoning skills are definitely improving!
HIGHLY RECOMMEND TRY STARTING WITH LEVEL 1

I normally have a hard time finding Sudoku puzzles that are challenging to solve, but decided to take a stab at these. The puzzles provide a nice balance from fairly easy to complete in a minute or so, to fairly difficult. It's refreshing to have the range, and I will likely purchase more of these after finishing this one.Was this review helpful? Yes NoThank you for your feedback.
