As I re-dip my toes into the ever popular “pick up and play” genre, there is definitely no shortage of titles for me to choose from. The problem with a lot of the titles is that although the idea of a casual or pick up game is fairly simple in theory, the ability to make it unknowingly addictive is far more difficult. One formula that a lot of developers seem to be trying to follow is to take online flash based games and port them to the idevice platform. This again is another example that although the idea and even the execution is fairly easy, successfully porting the addictiveness of those games doesn’t always work. Concrete Software however has, in my opinion succeeded on both accounts.
