Week 2 project

Blackjack game

Tasks

set up initial classes and values

deal 4 cards

player plays

dealer plays (draws on 16, stands on 17)

determine winner

continue playing?

design decision - restrict the game to a single (non-dealer) player

less versatile, but much easier to implement

increasing flexibility
