I really had no clue on what to expect when I first started playing the Windows Phone game LeaderFlip. It's a jumper game where you jump various world leaders as high as you can in an effort to reach the moon.
Now you might say, "Joy, another jumper game" but LeaderFlip was surprising fun to play. You have enough bonuses to help boost your way up the screen (some in a rather creative way) to keep things interesting. And in the end, while I don't see playing LeaderFlip for marathon sessions, it's not a bad time waster for short bits.
