How It's Made

Creating this chess puzzle game was a journey through web technologies and game logic. Here's a breakdown of the core components:

The Frontend

The interface is built using pure HTML5 and CSS3. I used advanced CSS techniques like Flexbox, Grid, and Backdrop Filters to create a modern, "glassmorphism" inspired aesthetic. The design is fully responsive, ensuring a great experience on both desktop and mobile devices.

The Logic

The core chess logic, including move validation, game state management, and puzzle handling, is powered by Chess.js. This library handles all the heavy lifting of the rules of chess.

The Board

To render the chessboard and allow for interactive piece movement, I integrated Chessboard.js. It provides a clean and efficient way to display the board and handle drag-and-drop interactions.

The AI Engine

The most challenging part was integrating a powerful chess engine. I utilized Stockfish, one of the strongest chess engines in the world, running via WebAssembly (WASM) directly in the browser. This allows for high-performance AI analysis without needing a backend server.

The Challenges

One of the biggest hurdles was managing the performance of the Stockfish engine within the browser environment and ensuring the UI remained smooth and responsive during intense computations. Overcoming this required careful optimization of the asynchronous communication between the main thread and the engine worker.
