We play Catan and other two-dice games a lot, and always get into arguments about short-term vs. long-term statistics as to how well the dice are doing.
We’ve therefore made a two-dice rolling program in Unity that’s fairly cheesy, but does count statistics about what’s been rolled so that you can see the distribution.
It also supports a different “perfect” distribution by making all possible two-dice sequences, and then choosing one of them to go through all possible rolls, thus determining that all combinations will be covered.
