Game of Battleship and having fun with SignalR

Over the past couple of weeks I have been learning and playing around with SignalR. To put it in action I put together another personal project: this time a classic game of Battleship. It supports external authentication with Google using OWIN, a lobby of logged-in players where one can challenge another to a match, and an in-game chat for good measure (because all SignalR samples must have a chat some where). As always I ended up spending more time struggling with my rudimentary CSS skills trying to make it look decent.

You can play around with it here: http://battle-ship.azurewebsites.net/
