zatyka Thanks for the info, that is very useful information.
I am working on a similar game type mechanic for a regular playing card game, such as a standard 5 card draw.
For the server side, I will be using the SignalR library for Microsoft .NET. I am still in the early prototyping but my goal is to integrate the SignalR library for server side events with C2. The client side for SignalR can be coded JavaScript.
The big advantage of SignalR is it will use the best available transport method for the user browser. It can use WebSocket or Long Polling without any different coding.
I will do a new posting when I will have a completed prototype.
