Hello. I'm going to tell you about a great site for getting free Ultimate Game Cards and other gaming goods for completing simple offers.
So, to start off go to http://tinyurl.com/PrizeRebelFreeUGC and make a new account. Activate it and you can start earning points. Just go to the "Get Points" tab and you will find tons of easy offers that will give you points. Most of them will just requier some simple information and/or an email validation. I you don't want to use your own personal info you can go to http://www.fakenamegenerator.com/ and get the info you need. Althouth it might not work for all the offers, but it will work for most of them. Another way of earning points is to getting your friends register on your referral and do the offers for you.
After you have collected enough points, go to the prize section. Just click on the Ultimate Game Card and redeem one. Wait a few days the code will be sent to you. There are also many more amazing prizes you can get for free like OGPlanet Game Codes, League of Legends Game Cards or even a World of Warcraft Game Card.
Good Luck :)
