You Can Get a Mystery PC Game for 6 Cents

[UPDATE] Both the Birthday Mystery Bundle and $1 one-game pack are out of stock. The original story follows:

If you feel lucky and have six cents to spare, Green Man Gaming currently offers a "Birthday Mystery Bundle" as part of its sixth anniversary. The bundle includes one random, unknown PC game. The catch? You might have to play it on Uplay.

However, the bundle might instead contain a key for a game on Steam, Origin, or GOG. The game is completely random, as one player posted on the website that they received American Truck Simulator, while another got Call of Duty: Black Ops.

Green Man Gaming also has four other Mystery Bundles that you can purchase. The one-game pack is $1, the three-pack costs $5, the five-pack costs $7, and the seven-pack will run you $10. The same conditions apply for these packs, which means you could get a mix of games from any of the aforementioned PC game clients.
