EconoSim: A Game of Choices

💡 Inspiration

EconoSim was born out of our passion to simplify complex economic concepts through interactive learning. During Hackonomics 2025, we wanted to build something that merges Computer Science with Economics — not just to analyze numbers, but to empower users to experiment and learn by doing. We envisioned a platform where anyone, from students to casual learners, could simulate economic decisions and instantly observe their effects.

⚙️ What It Does

EconoSim is a web-based simulation game where users act as policymakers. By adjusting sliders for tax rates, government spending, and interest rates, players can instantly see how their choices impact three key indicators:

GDP Growth
Unemployment
Inflation

The game uses a simple, intuitive interface and provides immediate feedback, making economic cause-and-effect feel more tangible.

🛠️ How We Built It

We built EconoSim using:

HTML5 and CSS3 for structure and styling
JavaScript (Vanilla) for interactive logic and real-time calculations
Google Fonts (Inter) for a clean and modern visual feel
GitHub Pages for deployment and hosting

The economic model behind the game is intentionally simplified to prioritize clarity and learning over realism. We focused on building a responsive and engaging front-end experience without requiring backend complexity.

🚧 Challenges We Ran Into

Simplifying economic models: Striking a balance between accuracy and educational clarity was tricky. We didn’t want to overwhelm users with complexity, but we also didn’t want to oversimplify.
Designing an intuitive UI: It took time to create a layout that looked clean on both desktop and mobile without using frameworks.
Polishing without over-engineering: Since it’s a prototype built during a hackathon, we had to prioritize speed and clarity while resisting the urge to add too many features.

🏆 Accomplishments That We're Proud Of

Built a fully functional, responsive simulation game in a short time frame.
Delivered a tool that makes economics fun and interactive.
Successfully deployed the app live on GitHub Pages.
