If you're a fan of the Transformers, you can enter to win Transformers Prime for the WiiU. Or, if you prefer a military FPS, you could enter to win Call of Duty: Black Ops II for the WiiU. Feel free to enter both contests to increase your chances of winning a prize, but two separate winners will be selected; you cannot win both prizes.
You can enter each contest up to once per day, per email address. If you're under 18, get a relative to enter on your behalf; these contests are open to people 18 years or older in the Continental United States.
