Brown Belt KenKen® (Martial Arts Puzzles Series)

This book consists of 8x8 and 9x9 puzzles, 1 of each to a page. I've given the book 4 stars because the format of 2 on each page means that there isn't a great deal of space for writing when working out the more complex maths. I've completed about 20 of them and so far they are suitably challenging without being impossible.

Great for those who are used-to KenKen.In fact, a god-send for those who don't need the easier or introductory puzzles.This book contains only 8x8 and 9x9 puzzles.This is the book we have been waiting for!

It really keeps my brain engaged in finding the solutions which are there, somewhere.

Harder than I expected! Should have gone for the green belt but keeps my brain active.

I thought these were quite difficult compared to the ones i did before. But great!

Harder than I expected

Never fails to impress
