|

Simple webapp to keep track of who is currently playing and how much time they have left. Originally designed for [Rummikub](https://de.wikipedia.org/wiki/Rummikub).
|
||||
Please note: this is by no means perfect and just meant to be a simple solution to a simple problem :)
|
||||
|
||||
# Featues
|
||||
- Create an independent room
|
||||
- Play with multiple players across multiple devices
|
||||
- Decentralized
|
||||
- End-to-end encrypted
|
||||
|
||||
# How it works
|
||||
The browsers of all players connect to a common MQTT server and communicate through that server. An AES Key is derived from the room name, which is then used to encrypt all communication.
|
||||
|
||||
