    More than just the d100 he was a pioneer of being very exacting when it came to making polyhedral dice. See http://www.1000d4.com/2013/02/14/how-true-are-your-d20s/

      Absolutely, but i couldn't fit all of that into the subject line ;) and he's best known for the d100. Many of us remember the articles and ads from the 1980s describing the effort he put into that particular die.

    I didn't see a picture of Zocchi's d100, Wikipedia has one

      Interesting they had to redistribute the numbers to take account of its natural bias.

    I've never played any games that require this, but the Wikipedia page makes reference to percentage rolls, but wouldn't you need 101 sides to get 0% and 100% for that?

      There is no 0% in d100/d-percentile rolls. Every "how to interpret these dice" paragraph in games which use them will tell you to interpret 0-0 on 2d10 as 100, not 0. Or, hypothetically (but i don't recall having ever seen this), they'll have a stated range of 0 to 99 (inclusive). Either way, the numeric range spans precisely 100 digits.

    I just throw 17d6 and subtract 2.

    Problem solved.

    (I am joking!)
