Glitch Hunters: Can You Save the Game?
The arcade is glitching—and you’re on the rescue team!
Investigate what’s going wrong, edit real JavaScript, and test your repairs. No coding experience needed—just curiosity and a willingness to experiment.
Start with the three Intro missions, designed for a 45-minute workshop. Then explore Fundamentals, Objects & Classes, and Bonus missions at your own pace. Ready for a bigger challenge? Mission 12 combines your skills into one complete game rescue.
Your mission: Observe → Predict → Edit → Run → Check → Explain.
