We really should team up with some high-ranking game on the App Store or Android Marketplaces and offer the people who achieve a certain highscore some sort of prize money. This would be a perfect way of promoting Bitcoin! I think I'll go and create a thread!
That sounds like an interesting idea! I wonder if people already thought of that before, but I can't seem to find anything, nor do I remember this idea being stated before. I wonder which developers would be willing to do this experiment!
Actually yes, someone here already thought of that (and probably others before): Gravitate created "The Ponz" (https://bitcointalk.org/index.php?topic=668391.0).
Try goldentowns. It takes quite lot of time to get some earnings, but its nice game and fun
I played GoldenTowns for some months, but only managed to get 0.01 btc out of it - play it if you like the game, but don't expect to get a lot more out of it.
Another game of this kind is MarketGlory - you can also withdraw your in-game earnings (though I'm not sure btc withdrawal is available), but unless you invest your own money in the game, expect several months worth of repetitive daily tasks without any return.
EDIT: Remembered another one: GoldenBattles.
