Google is here at CES showing off all its fun stuff and searching software. But that's not all, the company is also giving away fun prizes...provided you know your Google. To get the free swag, Google has provided everyone with these circular cardboard scratch off games. Five questions about Google are on one side and you can scratch off the answer. You then have to answer the question by scratching off the correct answer. Doing so reveals a green star which if you get all five correct, you'll score a sexy Google t-shirt. Get one right and you're walking away with silly magnets with the Google logo. Questions include trivia such as: "What is the latest Gmail feature we've added?" or something of that nature. You can bet we here at Gizmodo blew through the questions with ease and walked away fully clothed. Thanks, G.
