BlackJack Game - Python Implementation

Overview

This repository contains a Python implementation of a simple BlackJack game. The game allows a player to play against a dealer (simulated by the program), with functionalities such as betting, insurance, and double down.

Features

• Deck Management: A standard deck of 52 cards is used, shuffled at the beginning of each round.
• Betting System: Players start with a balance of $100 and can place bets each round. The game ends when the balance reaches zero.
• Insurance Bet: If the dealer's visible card is an Ace, players have the option to place an insurance bet to hedge against a potential BlackJack.
• Double Down: Players can choose to double their bet and receive exactly one more card.
• Gameplay Options: Players can choose to hit (draw another card), stand (end their turn), or double down during their turn.
• Winner Determination: The game determines the winner based on standard BlackJack rules and updates the player's balance accordingly.
