Since furtheron obviously die1==die2, the following part of code
seems needlessly overcomplicated.

Because ^ here is one "branch" that doesn't currently return.
I mean the "else if"'s (missing) "else" case, where
noDoubles == true is true
(die1 == die2) && (die1 != 6 || die2 != 6) is false
die1 == 6 || die2 == 6 is false
As a human, we can see, that this combination cannot happen
due to equal dice, but apparently the Java compiler cannot.
