A port of the browser game Cookie Clicker is in works for Android and may also be on the way to iOS.(http://orteil.dashnet.org/cookieclicker/) I don't why, but this game got me hooked - try it, if you haven't!
FYI, there is a game called "Cookie Clickers" that was launched to the app store not too long ago. Its not the official port, nor is it half as good!
Yeah, I saw it and it's true, it is nowhere near as good - they even made one themed around sushi instead cookies. I also read on the original game's forum, that the developer is not too fond of these "knock-offs".
I'm not sure what's the point of this sort of games. An excuse to kill time? I did made 500 clicks in Cookie Clicker, but... stop when my mouse screamed in agony.
Me neither. To some, it just got that addiction factor - just one more upgrade/achievement. I admit it died pretty quickly for me too, but apparently, there's a dungeon-system upcoming, adding more depth and RPG-like elements.
