As far as traditional games go this month, EA's FIFA 13 tops the iPhone Qi league table for September 2012, though it does trail the poker assistant app Poker Tools overall.
In good news for soccer fans worldwide, the latest iteration in EA's famed footy franchise has improved its teamwork, finally supplying online play.
Following close behind EA's footballing masterclass, God of Blades brings a dose of epic fantasy and prog rock excess to the endless-runner market.
Speaking of running, Rayman Jungle Run - at #5 - has been winning plenty of plaudits for its stunning take on the platforming speedrun genre.
