More like question to developers, IDK really, maybe somebody else knows the inner workings. Now, I was running some explore with Elspeth and noticed that on the starting board, when you are casting on the first turn, number of skulls are on average lower than number of other colored gems. And no, I am not imagining things, I have a data set that confirms this. And the difference is quite substantial.
Is this intended?
Now, do subsequent skulls dropped during the match also have reduced frequency compared to other colors or is this a feature for board generation only?
Also, I’m getting a bit paranoid but I think I should run a few statistical tests to check whether the random in GoW is actually random. Obviously, running some Diehard tests is impossible (since they require raw continuous output) but I can generate random simulation with some other pRNG, check whether it is actually random, and compare simulated output to GoW output to see what is going on. It might even be possible to roughly estimate quality of pRNG output including skewness and kurtosis. Skewness can tell whether random is skewed and to what direction (plus or minus) and kurtosis is a rough indicator of how frequent is occurrence of low probability events.
I have a couple of hours free time, should be enough to collect the data and try to analyze.
