Exercise: Black Jack

Objectives:

To design and implement a web service hosted in the cloud (Azure) to support the game BlackJack

Background:

You have an Azure account see Create an account on Microsoft Azure

You have already implement a small test web service and hosted it in the Azure-cloud

The Black Jack Game play:

This card play is fairly simple. you have a Player (could be severeal player) and a Dealer. Player(s) and Dealer take one card at a time from a card deck.

The one who have the value closesed to 21 win - But you may not exeed 21. In this card game the suites have NO influence only the values. The values are the face value except for Knight, Queen and

King which all count 10 and the Ace can take the value 1 or 11. Two exsamples A) 7 of spades + knight of diamonds = 7 + 10 => 17. B) Ace of clubs + 5 spades = 1 + 5 => 6 OR 11 + 6 => 17.

The player starts with 2 cards. Then (S)he decide if another card should be added.

The player decides when to stop taking more cards. For the dealer the rules are more simple, the dealer takes card until he have at least the value 17.

Hints

When developing the web services it is good practice to try the different steps locally before publishing the web service in the cloud (as you have notice p ublising take several minutes each time).

Exercises:

Make the model classes

Make the model classes' i.e. a class 'Card' to present a single card and a 'Carddeck' to hold all the cards i.e. from ace to king in all 4 colors (clubs, diamonds, hearts, spades)

The Carddeck needed at least two methods

• Shuffle the carddeck
• Take the next card (the top of the stack)

Consider which datastucture is the best for 'Carddeck'.
Consider how to ensure the states i.e. when a card have been picked from the carddeck it can not been picked again.
(Hint: storage or for a start declare carddeck static)

Make the web interface for BlackJack part one - player

To make the Black Jack we have two parts - first the Player pick cards

Suggestions of methods to the player

• Start new game i.e. shuffle the cards ('StartGame')
• Start a player i.e. get the initial two cards ('StartPlayer')
• Pick another card ('GetNextCard')
• Perhaps calculate value of hand ('CalculateHand')
• Possibly hold i.e. no more cards (next player or eventually dealer) ('Stand')

Hint start with only one player

Make the web interface for BlackJack part two - dealer

After the player(s) have picked cards - then it is the dealer turn.

The dealer have strict rules to play the hand (see background) so the web service only have one service

• Play the dealer according the rules ('DealerPlay')

Make a consumer

Make a consumer that make use of the web service to show the black jack game
(this can be any program - Console, wpf, metro app ...).

Additional improvements

• The play could have several players
• Each play could bet money
• Each player could have a profile and save winnings to next time
• The web service hold the hands and the player only get a copy for avoiding cheating
• The rules (see https://www.blackjackinfo.com/blackjack-rules/ ) gives several variations - you could implement some of these

Extra games

• Make a Slot machine (dk: enarmet tyveknægt)
• Make tip,tap,toe (dk: tre på stribe)
• Make Ship battle (dk: sænke slagskibe)
