In Europe, Logitech is online with Jelly Jumper, a 50 levels advergames which challenges players to do their best with the keyboard. The game is quite sticky, and give the users one more reason to play: if the pass the 10th level, they get a 20 percent discount on Logitech products.

Long time I don't see a nice advergame which focus so much on hard selling/discounts. Good to see advergames aren't just a branding tool :-)
