Seems to be still in beta status. I will come back when site works proper.
Can you tell us what (you think) is not working?
Chat seems to not be working for me I do not have text input field to write message and also you should allow players to make more than one bet per round I do not see point in your rule 1 bet per round.
What browser you use?
I have tested (and working fine) on Chrome, Edge, Internet Explorer Firefox.
There is a chat field where you see: Type here to chat...
What is the point of more than 1 bet per round?
