Data (Rolls: 0):

This site automatically performs a chi-squared test on your input data. Basically, input the maximum amount of your dice in the first field (for the 00-90 dice, simply input it like a d10 and adjust your inputs accordingly), and input each throw into the second text area. This website will automatically execute a chi-squared test and tell you if your dice is likely fair or not. This basically implements the method of dice testing from https://rpg.stackexchange.com/questions/70802/how-can-i-test-whether-a-die-is-fair.

Also note: this only works until d20. Everything above that, is undefined behavior. And, you should definitely do a high amount of rolls, I recommend about 200.
