title: How does WiFi Lobby of Pocket Tanks work?
body: <p>There's a game called Pocket Tanks. What it offers is that 2 players can connect to same WiFi Network (like in home) and play the game together. Its different from internet multiplayer. It just needs common WiFi. I want to know how to implement such a system in my android game. I've tried to search it on Google but no helpful results. Any idea where do I even begin?</p>
  
  <p>Thanks.</p>
