Ever wondered if your special d20 is lucky or whether you needed to check it to see whether it’s off balance?

This video from Daniel Fisher should be used for good; not to find dice you may have innocently bought but now know are more likely to roll 20.

Daniel’s video doesn’t pull any punches either. Not only does he name Chessex as the maker of the bad dice he found, he cuts one open to expose what looks like a mismatch of chalky filling.

Back in 2012 Geek Native published some stats that compared GameScience dice to Chessex. The results suggested neither were truely random and, oddly, 14 was a bad number to pick.
