The Quality Index boasts over 45,000 reviews from websites like 148Apps, Pocket Gamer, and AppSpy, and uses a unique metric to create a single definitive score for each iPhone title.
21 years after brutally slamming onto the Atari, Speedball 2 has evolved into a touchscreen-friendly, Bluetooth-multiplayer ratings winner.
Tower Studios's futuristic baller managed to barge 2011's first bona fide breakout hit Tiny Wings into runner-up spot in February, and shoulder bump EA's NBA Jam into third.
Gameloft's experiment with the freemium business model, meanwhile, paid dividends, as Starfront: Collision battled in real-time to secure a high ranking place on the Quality Index chart.

N.B. While we only display the average score to one decimal place, the list is generated to further significant figures. We just don't show them all.
And, naturally, this is a static graph based on live listings which are subject to constant change as new releases and reviews emerge.
In order to provide a regular marker of the critical zeitgeist, however, we will continue to round up the best of the iPhone games released each month to provide the definitive Quality Index Top 10.
