Think of the hardest, most frustrating Android game you've played thus far. Is it Angry Birds, with its unparalleled addictiveness? Or how about Plants vs. Zombies, which has a seemingly infinite number of levels and is within spitting distance of Angry Birds' can't-put-it-down factor?

Or - dare I say it - perhaps none of the games you've downloaded from the Android Market have been difficult enough for you.
