Summary: Online Blackjack Game
Explore the essential design elements of an online Blackjack game by examining key requirements, system roles, and core class interactions. Understand how design principles like SOLID and patterns such as State and Iterator shape the system. Learn the workflow from game setup to payout, preparing you to approach similar object-oriented design challenges.
This lesson reinforces the core concepts of the online Blackjack game by reviewing its key requirements, system structure, and major design decisions. It reviews the key system requirements, outlines the core classes with their responsibilities and relationships, and highlights the major design principles applied. It also examines object interactions within the system and walks through the overall workflow to illustrate how the components collaborate to achieve the intended functionality.
Key requirements
The following are the main requirements for the system:
The system must support a shoe containing one or more standard decks, each consisting of 52 cards across four suits (Hearts, Diamonds, Clubs, Spades) and 13 ranks (Ace through King).
Cards must have specific point values: numbered cards equal their face value, face cards (Jack, Queen, King) are worth 10 points, and Aces are valued at 1 or 11, depending on the hand’s context.
The system includes two user roles: Player and Dealer.
Players must place a bet at the beginning of each round.
At the start of a round, the dealer deals two cards each to the player and themselves; the player’s cards are dealt face-up, while the dealer’s hand shows one card face-up and one face-down.
Players may choose to hit (draw an additional card) as long as their hand total remains under 21, or stand to end their turn.
The dealer must draw additional cards (hit) until reaching a minimum hand value of 17.
