Instead of using
if(BullCowCOunt.Bulls == WordLength)
bGameIsWon = true;
bGameIsWon = false;
You can simply just use
bGameIsWon = (BullCowCount.Bulls == WordLength);
it does the same thing, it sets the bool to true if the statement is true and to false if the statement is false!
Just thought I would share so you guys can clean up your code in the future if you would like!
