The amount of games that use those kinds of dice make his contribution to tabletop gaming incommensurable. Sad to see him passing. But 91 yo is more than respectable
The "Zocchihedron" is a single die with 100 sides, but most games that use a d100 simulate it with two d10s instead (reading the ones on one d10 and the tens on the other). So the truth is that Zocchi's die is more a novelty and less influential than it might appear at first if you take the title as written.
> Yeah, a real d100 is just too impractical for actual gameplay. Super neat, but two d10s is far more usable.
We had one for our AD&D sessions and we'd definitely be using it. AFAIR it didn't necessarily roll for very long but it was a bit hard to make sure what numbers was really the one at the top. Still: it had a cool factor.
