Java Game Development: Build a Tetrominos Puzzle Game

Creating your own 2D games is one of the most rewarding ways to master programming fundamentals. This course guides you through the entire process of building a classic Tetrominos puzzle game using Java's built-in graphics libraries. You will transition from writing basic command-line applications to structuring a complete, interactive desktop game. You will learn how to manage game states, render colorful grid-based blocks, and handle real-time player input. What you'll learn: Learn core game development concepts, including the game loop, coordinate systems, and tick rates. Design clean object-oriented structures using modern Java features like records for coordinate mapping. Implement 2D graphics rendering using Java's Swing and AWT libraries to draw and animate colorful puzzle blocks. Capture and process keyboard inputs to move, rotate, and drop active game pieces in real time. Build collision detection algorithms to manage boundary limits and clear completed horizontal lines. Structure game state logic to handle scoring, level progression, and game-over conditions. The course starts with foundational concepts of 2D coordinates and graphics rendering in Java, before guiding you step-by-step through block rotation math, game loop construction, and final polish. This text-only course is designed for beginners who have a basic grasp of Java syntax and want to apply their knowledge to a fun, practical project. No prior game development experience is required.
