This is a small collection of Java games I’ve been building, along with some basic reusable classes. The main goal was to learn and experiment with object-oriented design, data structures, and basic machine learning algorithms. Right now, everything runs in the console, but the structure should make it easy to add more games over time.
- Game class - Main menu that accesses the other classes to run games.
- Number Guesser – a simple guessing game where the player tries to find the hidden number.
- Tic-Tac-Toe – a full game against an AI that uses minimax with alpha-beta pruning, so it plays optimally.
- Blackjack – a full implementation of the classic card game, where the player can hit or stand against a dealer AI that follows standard rules, but will sometimes make risky plays. Features include ace value adjustment, bust detection, and replay options.
- Card and Deck classes – generic building blocks that can be reused for card-based games
src/
│── Card.java - Represents a single playing card
│── Deck.java - A deck with shuffle/draw methods
│── Game.java - Base class/interface for all games
│── NumberGuesser.java - The number guessing game
│── TicTacToe.java - Tic-Tac-Toe with an AI opponent
│── TreeNode.java - Helper for Tic-Tac-Toe AI game tree
Just open the project in your favorite IDE and run the classes directly.
All games share a common base (Game), so adding new ones is straightforward. The Tic-Tac-Toe bot evaluates moves with minimax and pruning, which means it won’t lose. Best case, you force a draw. Number Guesser is simple but a good example of input handling. Blackjack is the classic card game of
Some things I’d like to add in the future:
- A GUI so everything isn’t just in the console.
- More games (Blackjack, Poker, Connect Four, Checkers).
This project is mainly for learning and experimenting, but if you’ve got suggestions or ideas for new games, feel free to open an issue or PR.
