Casino Royale – A Decentralized AI-Powered Blackjack Experience

Play Blackjack against the house alongside AI-powered bots using advanced decision-making algorithms. This decentralized application (DApp) integrates blockchain-based monetary transactions and AI-driven strategy optimization.

Overview

Casino Royale is a decentralized Blackjack experience where players compete against the house alongside AI-driven bots. The project combines smart contracts, machine learning-based decision-making, and blockchain technology to create a next-generation casino experience.

Key Features

✅ AI-Powered Bots – Compete against six different bots powered by Neural Networks (NN), Reinforcement Learning (RL), Decision Trees, and Random Forests.
✅ Decentralized Blackjack DApp – Built using Solidity smart contracts, deployed via Truffle on a test blockchain using Ganache.
✅ MVC-Structured Backend – Clean, scalable, and modularized architecture.
✅ React.js Frontend – Interactive UI for seamless gameplay.
✅ Fair & Transparent Transactions – Smart contracts ensure fair payouts and decentralized casino operations.

Tech Stack

• Backend: Solidity (Smart Contracts), Truffle, Ganache, Node.js
• Frontend: React.js
• AI Models: Neural Networks (NN), Reinforcement Learning (RL), Decision Trees, Random Forests
• Blockchain: Ethereum (Testnet), Web3.js
• Development Tools: Python, Java (for early bot development), OpenGameArt (for assets)

Game Rules

Casino Royale follows a structured set of rules inspired by traditional Blackjack:
1️⃣ Played with 5 standard decks (52 cards each).
2️⃣ One house (dealer) vs. four players (3 AI bots + 1 human player).
3️⃣ Blackjack pays 3:2, as in real casinos.
4️⃣ Doubling and re-splitting after a split are restricted.
5️⃣ No insurance bets (dealer showing an Ace does not allow insurance).
6️⃣ Dealer must stand on 17 or above.
7️⃣ Minimum bet: $10.
8️⃣ Player can only Hit or Stand in the full-stack DApp for simplicity.
9️⃣ Bots in the CLI version can Hit, Stand, Double, Split, or Surrender like in a real casino.

🛠️ Installation & Setup

Backend (Solidity + Smart Contracts) Setup

1. Clone the repository:

   git clone https://github.com/MozartofCode/Blackjack-Bot.git
   cd Casino-Royale

2. Install dependencies:

   npm install -g truffle
   npm install

3. Start a local blockchain:

   ganache-cli

4. Deploy the smart contracts:

   truffle migrate --reset

Frontend (React.js) Setup

1. Navigate to the frontend directory:

   cd client

2. Install dependencies:

   npm install

3. Run the frontend:

   npm start

Bots & AI Analysis

For AI-driven bots and simulations:

python bot_analysis.py

This script runs AI-powered bots against the house and evaluates profitability based on a 30% profit threshold.

AI Bot Analysis

The AI models are trained to maximize profits using various strategies:

• Neural Networks (NN) – Self-learning bot that adapts based on game outcomes.
• Reinforcement Learning (RL) – Uses Q-learning to optimize decision-making.
• Decision Trees & Random Forests – Predicts the best moves based on historical game data.
• Random Bot – A baseline comparison using purely random moves.

Each bot's win rate and profit percentage are analyzed over thousands of games to determine the most effective strategy.

Future Enhancements

🔹 Integrate a Metamask Web3 wallet for real blockchain transactions.
🔹 Expand AI strategies with Deep Q Networks (DQN).
🔹 Implement additional Blackjack features like splitting, doubling down, and insurance in the DApp version.
🔹 Multiplayer support for real-time decentralized gameplay.

🏆 Project Inspiration

This project was inspired by the movie "21", where a team of MIT students successfully applied card counting strategies to Blackjack. The initial bot was built in Java and later evolved into an AI-powered system with advanced ML models.
