The Quality Index boasts over 110,000 reviews from websites like 148Apps, Pocket Gamer, and TouchMyApps, and uses a unique metric to create a single definitive score for each iPhone title.
Architectural blueprint rotation might not seem like the most likely formula for iPhone gaming fun, but this offbeat combination of concepts has propelled Blueprint 3D right to the top of the Qi leaderboard this month.
It narrowly beats Ravenmark: Scourge of Estellion to pole position in November 2011, with Witching Hour Studioss original and fantastical turn-based strategy game proving a big hit with iPhone reviewers across the planet.
Demonstrating that the appeal of mashing zombies remains as strong as ever, meanwhile, is Chillingos top-down shooter Extraction: Project Outbreak, which sees you going flesh-coloured head to flesh-eating head. Great controls and a robust upgrade system drive this one up to fourth place on the Qi games chart, in the process fending off some - ahem - stiff competition from Bulkypix's Corpse Granny.

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 ten.
