there you go

bool levelFinished;
int rubies=0;
int rubyReward=7;
int rubyMax=50;

while (rubies < rubyMax) {
  rubies += rubyReward;
}

levelFinished = true;

just wondering what this does again "rubies += rubyReward" ? Kind of foggy about that...

its just a shorthand operator

its equivalent to doing:

rubies = rubies + rubyReward
