Will Shortz Presents I Can KenKen! Volume 1

The book is in terrible condition. It is NOT in "good" condition. More than half of the KenKen book is completed and the covered has been written all over it. So disappointing.

"I Can Kenken vol. 1 " is a great little book for kids, especially those about 8 or 9, but adults like myself can also have fun with it. There is an introduction with instructions and hints about how to do kenken. The 75 puzzles start off very easily using only the numbers 1,2, or 3 and gradually progress to using 4, then 5 and finally finish with numbers 1 through 6. The whole book uses addition as the only operation and each kenken puzzle is rated from easy, to moderate to difficult. Although it's quite easy for an adult, I've still enjoyed using "I Can Kenken Vol. 1" and have quickly progressed to more difficult Kenken puzzles in other books. So, now "I Can Kenken" too. It's probably best for kids, though.
