Burning question: How to connect mobile devices to a computer in order to do multiplayer games.

We are trying to make a card game on Air Console, which is a website that allows you playing games on it. You use your phone as a controller. We chose card game because card games’ idea are quite simple, but fun. Also, there is not much card games on Air Console, that is why we decided to make a card game on Air Console. I am going to know how to code in HTML after this project. We might do a remix on a card game instead of the original card game, but this is just an idea.
