This is an old code-breaking game, Bulls and Cows, also known as 猜數字 or AABB.

In order to learn GCP Firebase, I try to setup this project repository to record my learning progress. First stage is a pure web frontend, pure javascript based, platform. Then, I will setup the project to Firebase by modifying the sample, FriendlyChat, to meet our needs.

1. First trial: Web Frontend Stage
2. Firebase trial:
   • User as guest
   • User as host
3. Firebase trial:
   • User as guest
   • User as host
   • Competition
   • One host vs. many guests

Since the samples from Firebase Codelab are using the Apache License 2.0, I will try to use the same one. See LICENSE
