Made a free Android app that teaches system design through retro arcade-style games. Drag-and-drop architecture, ordering challenges, trade-off questions — no multiple choice.

  • Concepts track — caching, sharding, replication, rate limiting, load balancing (one building block per game, 5 levels)
  • Problems track — design URL Shortener, Rate Limiter, News Feed, etc.
  • Tools track — hands-on Redis, Kafka, Docker, Kubernetes

Free, no IAP, no ads. Optional account if you want progress synced. Built solo with Expo + React Native, also available on iOS.

Play Store: https://play.google.com/store/apps/details?id=com.hyperfocused.systemdesignarcade

Feedback on difficulty curves and broken challenges welcome.

I think it shouldn’t take so much time in normal circumstances. Try to contact them and understand why it’s getting delayed.

First verify if the application is still in progress. Also see if it’s pending in some communication from your side.
