I have written a roulette game using Java and Java FX.
It now need to be converted into a Client/Server multi-player game.
The client needs to remain a stand alone application while the game logic should be transferred into the server.
Infrastructure for the Client/Server (Protocol etc) should probably be sufficient so all I'll have to do is writing the 'logic' and the infrastructure (and protocol) do the rest.
A file is attached with some more instructions and details.
