Hanabi play online

NOTE: Google has deprecated their turn-based multiplayer games API as of March 31st: https://support.google.com/googleplay/android-developer/answer/9469745.
Because of this, the app is *currently not usable*. I'll try to fix things, but this will require a rewrite of most of the backend logic of the app. I expect this will take a few weeks at least, if I can work things out at all.

If you happen to have experience with Firebase and/or Open Match, feel free to reach out to help me :)

Hanabi is a card game where you can only see the cards of the other players! The goal as a team is to play as much cards as possible before the deck is empty.
