"Language": "en_us",
"Programming Language": "Python",
"Original Requirements": "write a cli blackjack game",
"Project Name": "cli_blackjack_game",
"Product Goals": [
"Create an engaging and interactive CLI experience",
"Ensure the game logic is accurate and fair",
"Provide clear instructions and feedback to the player"
],
"User Stories": [
"As a player, I want to start a new game easily from the command line",
"As a player, I want to see my current hand and score after each move",
"As a player, I want to receive feedback on winning or losing a round",
"As a player, I want to be able to play multiple rounds without restarting the program",
"As a player, I want to have the option to quit the game at any time"
],

"CLI Blackjack A: Simple interface, lacks detailed instructions",
"CLI Blackjack B: Good game logic but no option to quit mid-game",
"CLI Blackjack C: Provides feedback but has a confusing user interface",
"CLI Blackjack D: Engaging but lacks multiple round support",
"CLI Blackjack E: Accurate game logic but minimal user interaction"

"Implementation approach": "We will implement a command-line interface (CLI) Blackjack game using Python. The game will focus on simplicity and user engagement, ensuring clear instructions and feedback. We will use the 'cmd' module from Python's standard library to handle the command-line interface, which will allow us to manage user inputs and game flow effectively. The game logic will be implemented in a separate module to maintain clean separation of concerns. We will not include advanced features like betting or card counting at this stage to keep the game simple and focused on core Blackjack mechanics.",

1. Yes, the code is implemented as per the requirements. It provides a basic Blackjack game with the necessary classes and methods.
2. Yes, the code logic is correct. The game correctly handles card dealing, score calculation, and determining the winner.
3. Yes, the existing code follows the "Data structures and interfaces" as described in the system design.
4. Yes, all functions are implemented as required. The methods for dealing cards, calculating scores, and determining the winner are all present.
5. Yes, all necessary pre-dependencies have been imported. The code uses Python's standard library, and no additional imports are needed.
6. Yes, methods from other files are being reused correctly. The `Game` class is designed to be imported and used in `main.py`.
