Now, if you must roll 7 or more to succeed, you fail if you roll 6 or less, which you have a 30% of experiencing. If you have data to support the fact that you roll 6 or less 75% of the time, I'd be happy to see it.
Random number generators are not super difficult programs to write. So I think a serious amount of data would be required to test the random number generator they are using and reject the hypothesis that it's a good one.
Does this game have some kind of log file that I can track rolls? I'll be happy to start tracking and provide all the data you want.
