Second-Degree Black Belt KenKen® (Martial Arts Puzzles Series)

I love KenKen puzzles, and just completed puzzle 150. I was quite surprised and disappointed to turn the page and discover the remaining 150 puzzles in the book are Operationless. I don't enjoy those puzzles and don't find them relaxing like I find the puzzles with Operations. Some are obviously multiplication or subtraction. But it requires an elevated degree of logic and thought and deductive reasoning which is OK in itself; but after working a full day, isn't particularly relaxing. The book cover and description on Amazon should have indicated this because the second half of the book is wasted on me. It should have been described that way and I wouldn't have purchased it.

I’ve done hundreds of “difficult” Will Shortz kenkens and consider myself pretty good at them, and these are difficult for me. They take a while, often a couple of sittings. There are 2 on each page, which isn’t ideal, but not that big of a deal either. There are 300 puzzles total, so this should last a long time for me.

Great puzzles. But they should nyhave 2 puzzles on 2 page. Very hard to work in small boxes

Exactly as it is advertised, great book.

Very good selection of puzzles – – challenging but not impossible.
