Build a Memory Card Matching Game
In this project, we’ll build a fast-paced memory card game in which players flip emoji cards to find matching pairs. The game features five difficulty levels—from Tiny to Expert—and tracks both move count and elapsed time. High scores are saved per level, allowing players to monitor their performance and improve over time.
Everything we see onscreen—card layout, interaction logic, scoring—will be implemented in TypeScript. We’ll drive the game forward one small task at a time, going from static HTML to a fully interactive, stateful browser app.
Hands-on TypeScript practice: Reinforce our understanding of types, unions, event handling, and DOM APIs.
Real-world patterns: Build reusable functions, manage global state, and implement responsive UI updates with clean logic.
Incremental design: Learn how to break down a non-trivial app into testable, maintainable pieces, just like in professional projects.
Something to show off: Walk away with a fun, functional game that’s easy to demo and extend.
By the end of this project, we will have:
Used discriminated unions and interfaces to model game state with precision.
Written a generic shuffle function with strong type safety.
Manipulated the DOM using strictly typed elements.
Managed UI and logic updates with typed event handlers.
Built helper functions with type-safe keys for localStorage.
Practiced organizing code with clear, maintainable TypeScript patterns.
This is a complete, frontend TypeScript project hiding behind a simple game. It’s fast to build, satisfying to play, and a rock-solid way to put our skills to the test. Let’s get started.
