Welcome to the final weekly iPhone Quality index (Qi) games round-up of 2010, which has been giving you the LOWdown on the HIGH scorers every Friday on these hallowed pages.

Launched in beta by Steel Media, publisher of PocketGamer.biz, Qi trawls the web for iPhone game and app reviews from the world’s most respected online and print sources.
Qi then applies its own magic formula to each site (such as 148Apps, Macworld, IGN, and Gamezebo) to establish a single definitive Qi score for each iPhone app and game.

Mystified

Reaching out to a new generation of graphic adventure players on iOS, Cyan’s mammoth follow-up to the groundbreaking Myst has puzzled its way onto the Qi chart this week in third place.

A trio of meticulously crafted reviews have handed Riven a powerful 9.2 Qi rating, the story of which is set immediately after the events of Myst and centres on the destructive rule of the eponymous island by the self-appointed Gehn.

Immersive point-and-click gameplay, involving the deciphering of codes and whatnot, appealed to TouchGen on review, who concluded that, “it is a great port with a good save system, bookmarks and multitasking compatibility. The puzzles are intriguing, and the game world is immense.”

Hole in two

After Real Racing 2’s and N.O.V.A. 2’s grand Qi feats last week – and, of course, Riven’s recent escapades above - it’s clear to one and all that sequels are most definitely the RAGE (HD) right now on the App Store.

Another to add to the burgeoning list is the next round of Noodlecake’s platforming-cum-physics series, distinguished from its predecessor by the ‘Super’ prefix. The original itself shot onto Qi’s leaderboard in November, a feat its younger brother was delighted to repeat over the last seven days.

Totting up a 9.1 scorecard from two professional iPhone analysts, Super Stick Golf has landed sweetly on the Qi green, its maker lauded by 148Apps: “they refined what worked, added elements that make the game feel fresh, and loaded the game down with plenty of content.”

Five portions a day

Before catapulting onto Qi’s Top 10 rundown, FDG Entertainment’s Cover Orange had tasted success as a Flash gaming sensation, its drag and drop puzzle mechanism finding plenty of admirers across the world.

A mischievous cloud overhead is threatening to pour acid rain over the precious orange population, so – guess what? – you must squeeze every drop of logical and lateral thinking from your overworked Xmas brain to protect the juicy favourites.
