Welcome to the weekly iPhone Quality Index (Qi) games round-up, giving you the LOWdown on the HIGH scorers every Friday on these illustrious pages.

As you may already know, Qi trawls the web for iPhone game reviews from the world’s most respected online and print sources.
Qi then applies its own magic formula to each site (such as 148Apps, IGN, and AppSpy) to establish a single definitive Qi score for each iPhone game.

Nothing but net

Slam dunking onto Qi’s Eastern Conference ladder this Friday shoots Electronic Arts’s slice of 2-on-2 basketball action, which plants its oversized flag - and bonces - firmly in the arcade, rather than simulator, camp.

Almost overnight, a quartet of scorers have adjudicated on NBA Jam’s transition from console to iPhone, resulting in a blazing hot 9.0 Qi rating for this frenetically paced trip down memory lane.

Select your favourite NBA team, lace up your virtual boots, and forget about anything as trifling as rules or regulations, when you line up the next in-your-face monster jam.
TouchGen commentated on NBA Jam’s presentational triple-threat, highlighting that “the graphics are also very nice” and “the music and narration also adds to the NBA Jam feeling, where you will hear what we have all been accustomed to by now, the amazing 'Boomshakalaka!' and some more.”

Ultimate Force

Head-to-head combat of a different kind marches triumphantly onto Qi’s Top 10 leaderboard this week, as the maker of the highly rated Zombieville USA and OMG Pirates! commands an army of four positive reviews for Battleheart.

Mika Mobile has managed to extract the finest elements from both the role-playing and real-time strategy genres, delivering a dense campaign mode comprising 30-odd levels and hugely customisable characters.

Recruit new members to your wandering party and upgrade their equipment in this charmingly drawn battle of wits, where sorcery sits comfortably alongside meteor strikes.

The mechanism for manoeuvring your knights and wizards across the arenas was detailed by AppSpy in review: “Swiping and tapping forms the main system of control for your adventurers.

“Each one can be selected individually and either moved or given a target by swiping across the screen to a new location or a foe to attack them.”
