I found this fascinating, if true:
> The reason casino dice have such sharp edges is to get the to stop rolling faster with fewer tumbling. The more a die tumbles the more likely it will present any issues with it.
If I understand it correctly, the justification is this: if a die is biased (usually a heavier face), this bias will manifest with a higher chance the longer the die rolls. But if it stops abruptly, for whatever reason (bumping against the edge of the table, other dice, or having a shape that prevents longer roll time, like the casino dice) this bias will be less likely to manifest. Did I get this explanation right?
This reminds me of a D&D dice website that went into way too much detail about how they weren't fair and I remember photos of them stacked on top of each other to show the variations in manufacturing.
The thread following the review is pretty interesting too!
Reminds me of an encounter on BoardGameArena where the top ranked 7 Wonders Duel player complained there was a randomization bug (the Great Library never offered the science progress token). I thought he was raging (who hasn’t heard a poker player complain about bad luck) but turns out the developer checked the code and did in fact find this was a bug!
