I am not sure what Kiip does but at first I thought it did the following (feel free to take the idea, if you make money, donate some to the free software community):<p>Combine the gratification from in-game achievements ("You sliced 5 bananas in a row") and "reward" the player with some advertisements (like coupons, "You are great, you know what else is great? $product"). I think this might lead to crazy click-through rates.<p>No idea if that is what it does, it does sound like it. But maybe not? I cannot code this. I don't believe in software patents or "intellectual property". The idea is nothing special. Have fun!
