Just found it, haven't tried it, it might be quite fun (Google maps and monopoly joining forces)
EDIT: The website is being smashed so you probably won't be able to load the game after clicking 'Play' on the main page D:
EDIT 2: I got in on my second try
EDIT 3: Trying to buy a street but it doesn't detect any as available, it just told me there's too much strain on the servers
