I didn't know there was a book, but here's a review of it:

that is nice enough to repeat the challenge questions.
(Looks as though the goal was 50 digits, not just 10.)
The goal was 10 digits for each of the 10 problems, hence "100-digit challenge". On most of them some of the contestants calculated a lot more than that. The book explains how to get 10k digits on nine of them. (The exception is the third problem, to find the norm of a certain linear operator on a Hilbert space. They found 273 digits of that after months of computation.) (The announcement said "If anyone gets 50 digits, I will be impressed". In the event, there were 20 teams with 100 correct digits and a few more with 99.) -- g
