New Zynga Facebook game announced in Zynga Lotto

Zynga Lotto Grand Prize
No one expected Zynga to create a daily, free, scratch-off online lottery that caters specifically to players of their games, but Zynga Lotto has been a hit since it came out in August. Fans really took to the opportunity of winning exclusive virtual items for their games, and it helps that using the lotto is a quick and hassle-free process.

Currently, Zynga Lotto offers a set of four prizes for each of five Zynga games: FarmVille, Mafia Wars, PetVille, YoVille, and FrontierVille. While those are certainly exciting for fans, I saw the most unexpected and amazing thing today -- a grand prize sneak peak to Zynga's newest fall game!
Zynga Lotto Grand Prize Find 3 Keys
This announcement has yet to appear anywhere else. Zynga making a sneak peak the grand prize is pretty cool, but it's downright bizarre to see a new game announced in the lotto system. All you've gotta do is find three Zynga keys when you play the lotto, and I got my first key today. To get a key, just play the lotto as you normally do. Also, the keys don't appear by scratching the Zynga Lotto cards. It's completely random. I scratched off my card, didn't win a game prize, but still got the pop-up window saying I had found "key 1 of 3".

Update: For those who want to know how easy it is to get all three keys and what happens when you do get them all, check out the image below:

Conclusion? It's ridiculously easy to get them. And once you do, they're going to remain vague about the big sneak peak, and you're going to have to wait for them to get back to you.
