Secure Code Game

Learn to code securely while having fun through our popular open source in-editor experience, designed for developers, students, and anyone curious about security. Get started for free in under 2 minutes, playing right from your browser. Over 10,000 players across industry and academia have already played. Visit gh.io/scg for testimonials and FAQs, and feel free to open a contribution to help make the game better for everyone.

In the latest season, you step inside a fully interactive AI coding assistant that turns natural language into bash commands, browses the web, connects to live data sources, runs org-approved skills, stores persistent memory, and orchestrates multi-agent workflows. Practice securing Agentic Workflows and Multi-Agent Communications as you work through five progressively harder levels. No AI or coding experience needed, just curiosity. Each season is self-contained, so you can jump straight into Season 3 or 4 without covering the earlier ones.

Getting started

1. Create your own copy

Click Use this template at the top of this repository, then select Create a new repository. Choose your personal account or an organization as the owner, and we recommend making it public so that it does not use Actions minutes.

2. Open a Codespace

All seasons are configured to run instantly in GitHub Codespaces. Be aware this will count towards your 60 hours of monthly free allowance.

• In your new repository, click the Code button and select Create codespace on main.
• Wait for extensions and background installations to complete. This takes less than three minutes.
• Pick any season from the table above, open its folder, and read the README.md to begin.

💡 If a banner asks you to create a virtual environment, dismiss it. You don't need one.
