The game, which was published by Chillingo and developed by Secret Exit, scored an astounding average score of 9.75 out of 10 in the six reviews on the sites included in the survey.
It was joined in the over-9s club by Mobigame's EDGE and Rake In Grass's Archibald's Adventures.
To qualify for inclusion, games had to be reviewed on at least three of sites listed at the bottom of this story.
The Top 20 games are as follows:
|3||Archibald's Adventures||Rake In Grass||3||9.00|
|4||Tic A Tac Poker||Treemo Labs||3||8.67|
|5||Blue Attack!||John Kooistra||4||8.65|
|6||The Oregon Trail||Gameloft||4||8.63|
|11||Ancient Frog||Ancient Workshop||3||8.33|
|16||Orions: Legend of Wizards||Chillingo||3||8.20|
|18||Tower Bloxx Deluxe 3D||Digital Chocolate||3||8.13|
|19||Chocolate Shop Frenzy||Digital Chocolate||3||8.10|
|20||Bobby Carrot Forever||FDG||4||8.03|
Meanwhile, we have also calculated a publishers index for Q1, based on iPhone game reviews on the covered sites.
It's good news for ngmoco, which comes top of the list with a healthy average rating of 8.38 from 12 reviews, followed by Gameloft and EA Mobile.
To qualify for this chart, publishers had to have had eight or more reviews during Q1 on the sites covered, from two or more different games. The full chart is:
|8||Namco Bandai Networks||13||7.03|
(If you're wondering what Konami did wrong, well, Metal Gear Solid Touch was reviewed lots, and fairly negatively).
UPDATE: The tables have now been amended to reflect the fact that Chillingo was the publisher of Zen Bound, which has moved it up one place in the publisher rankings.
Notes on methodology
Sites included in our research for this index were: Pocket Gamer, Pocket Gamer France, IGN Wireless, AirGamer, Mobile Game FAQs, Slide To Play, 148Apps, iPhone Games Network, Macworld, Games-Review, PiratesXXL and ProjectNext.
For those sites who do not give marks out of 10, they were adjusted (so we doubled the score for sites that mark out of 5, and divided it by 10 for those sites that mark out of 100).
The iPhone Quality Index will be published every quarter in 2009, and the games element will roll over to ensure games aren't penalised that are released on the cusp of two quarters. So, the games index published in three months' time will cover both Q1 and Q2, rather than simply Q2.
We will be adding other review sites next time round, and backfilling to ensure their reviews for Q1 are included.
