在各个平台的手机应用商店里面，一般存在两种下载行为，一种是提供付费下载，另外一种是免费下载。前者不乏经典案例比如Doodle Jump和angry birds各为他们的开发者带来了数百万美元的下载收入。后者也不失为一种良好的营销途径。

Backflip推出了免费下载的游戏Strike Knight，在10天内全球下载超过150万次，在多个国家位居免费游戏应用下载排行榜的前十位。好的免费游戏因为没有涉及到下载费用更加容易被用户采用，它将为开发者带来两个方面的利好，其一是因为高下载量获得广告赞助商的青睐，获得赞助收入；其二，可以为其他的收费游戏进行二次广告，带动收费游戏的下载。

Backflip公司首席执行官Julian Farrior表示他们很欣慰Strike Knight游戏能获得这样的下载成就。

后空翻公司

Perhaps it’s not surprising that the focus of most iPhone games analysis concerns the performance of paid products.

They’re more high profile, but as business models on the App Store fragment, plenty of companies are proving there are lots of other ways to succeed.

One of the prime examples is US outfit Backflip Studios, which has leveraged its catalog of free games to generate a massive number of monthly impressions, which it uses either to promote its paid games or to sell to thirdparty advertising networks such as AdMob or Quattro.

In order to keep growing however, it needs to keep releasing free games, and it’s finding an insatiable audience for its wares.

Strike every time

Latest release Strike Knight has been downloaded 1.5 million times in ten days and is in the top 10 free game charts in 60 countries.

“We’ve been extremely happy with the launch and the level of usage,” says Backflip CEO Julian Farrior.

“We are currently seeing roughly 500,000 sessions a day at about 5 minutes each from 250,000 unique daily users.

“This equates to about 1,750,000 ad impressions a day on gameplay pages with an average click through rate of 2.25 percent.”

And Backflip is continuing to roll out more content, with its most popular game Paper Toss coming to iPad, and new free games Grafitti Ball, Ninjump and Buganoids planned for iPhone in June.
