View 9 RepliesI'm trying to make a light version of a Blackjack game. The rules I need to use are as follows:
Ace = 1
Normal Cards = 2-10
Color Cards (king, queen, etc,) = 11
The dealer can keep hitting until it reaches 17 or under 21, he must always stay once it hits 17 or over (without busting obviously).
I know the ace normally should be 1 or 11 normally but I don't want to complicate things, I want to get the main thing of the program working first.
