37
After 250 rolls I can honestly say this D20 is the worst of the 17 I tested
(files.catbox.moe)
Out of 250 rolls 27 were 1's. A roughly 11% chance of rolling a 1 on this die.
For those curious about the rest:
Here's the stats for all 17
2 of my DnD group when they found out about my little project wanted me to check their favorite D20's as well.
Those are being tested this evening and I'm excited to see the results.
