Blackjack PEDA (but no C)

In this project, you are creating a playable game of Blackjack. If you haven't played this game ever, or in a while, grab a deck of cards and play a few games.


  • Practice the skills and ideas you have learned so far.
  • Effectively use loops, conditionals, and other control structures to implement control flows
  • Demonstrate usage of data structures to model resources.


Create a single-player blackjack game that plays against the house, i.e., a human player and computer dealer. You are free to create the user interface however you want, but keep it simple for Explorer Mode.

General Rules:

  • The game should be played with a standard deck of playing cards (52).

  • The house should be dealt two cards, hidden from the player until the house reveals its hand.

  • The player should be dealt two cards, visible to the player.

  • The player should have a chance to hit (i.e. be dealt another card) until they decide to stop or they bust (i.e. their total is over 21). At which point they lose regardless of the dealer's hand.

  • When the player stands, the house reveals its hand and hits (i.e. draw cards) until they have 17 or more.

  • If dealer goes over 21 the dealer loses.

  • The player should have two choices: "Hit" and "Stand."

  • Consider Aces to be worth 11, never 1.

  • The app should display the winner. For this mode, the winner is who is closer to a blackjack (21) without going over.

  • Ties go to the DEALER

  • There should be an option to play again. This should start a new game with a new full deck of 52 shuffled cards and new empty hands for the dealer and the player.

Explorer Mode

  • Generate a PEDA plan for your game. Don't worry about the "C"ode yet.
    • Redescribe the "P"roblem.
    • Demonstrate some "E"xamples of various player and dealer card situations. For example, if the player started with the 4 of clubs and the 5 of diamonds but then hit once to get the ten of spades before staying. Then the dealer revealed the 8 of clubs and the ten of diamonds. What happens, who wins. Do at least six of these types of examples
    • Figure out your "D"ata structure
      • This should list all of the classes you think you will create and their STATE (properties) and BEHAVIOR (methods). Here is a first hint. You will likely have a Card class that has two properties, a Face and a Suit and one method, Value that will compute how many points the card is worth.
      • Read the rest of the problem and figure out what other real world things you want to represent. They should have distinct properties and behaviors.
    • Figure out the "A"lgorithm for playing.
      • Can you write a step by step algorithm for playing the game?
      • You should be able to turn these instructions over to someone else and have them follow them step-by step like a recipe.
