Probability tester for my bustadice simulator. It will decide at each roll whether to skip or to bet and the game stats are referring to all games both skips/bets while play stats are referring to only the games which were bet on. It's made to test the sim mode and won't place any actual bets unless you turn off sim mode where in that case it wi…

Hey, I tried searching for a script that records my dice rolls history but I found one only for BAB. Do you have any for dice? Also BIG thanks for all the scripts you've created so far!

@Neonskull Yeah that's pretty easy to do, what exactly did you want it to save? and do what with it?

@dsetzer do you have discord or telegram so we can pay you for custom scripts?
