The game is called ‘Calx’ and is available for free in the Apple AppStore for iPodtouch, iPhone and iPod. It is an puzzle/arcade game and fits best into the match3 category. In principle the player has to select a simple math term and then its solution to score. There´s a video on YouTube that demonstrates the gameplay a little bit: http://www.youtube.com/watch?feature=player_embedded&v=G-bCVQ4jF7w
Of course the game has iOS Game Center integrated and brings 18 new achievements and a global leaderboard.
