I'll already talked about Playyoo Premium Program some weeks ago.
Basically, if you upload a game which include Playyoo API and it's cool enought, you may win 100$ each 5000 download.
Now, to add more and more great games, Playyoo gives you the first 100$ !!
It means that even if you never reach the 5000 download, you'll win 100$
Of course, it means you need to reach the 10000 download to win another 100$
Check Playyoo blog for more info.
Note Playyoo selects the games they want to include in the PPP and so give 100$).
