The New York Times Will Shortz Presents Diabolical KenKen

I like the range of difficulty because sometimes I want a challenge then there are times I just want to do a quicker puzzle. Other Shortz books I found too easy and with 300 puzzles, can't go wrong. Arrived in excellent condition.

Super hard and fun!

Bought as a secret Santa gift for someone who likes KENKEN. Was worried the “diabolical” would mean they’d get frustrated by it, but they were able to work through 10 puzzles on a day off. They appreciated the gift. Nice to sit with a pencil and paper sometimes instead of the online or app games.

If you're reasonably good at Kenken, you will not find very many of these 300 puzzles to be "diabolical". The 5 x 5's can mostly be done just about as fast as you can write. There were about 20 puzzles among the 7x7s and 9x9's which truly fit the description. Still, I enjoyed them.

Great gift for those who would be interested in what Cardinal Dolan has to say.

Husband is a big Ken Ken fan.

Fantastic puzzles! My son just loved them

and easier to spell. Once you KenKen you will be addicted. The puzzles in this book are not in "categories of difficulty" When I am challenged by one I am not sure if it was extra hard or if I was extra brain dead.
