Probably the hardworking team on the App Store, Pocket God developer Bolt Creative has just submitted its 27th update to the App Store.

What's more significant however is the audience reaction to its 26th.

This marked a split from the previous 25 as it made the game an OS 3.0 exclusive, shutting out current and new users from the future upgrade path unless they spend $5/£3 on the upgrade.

The reason for this was so the company could introduce optional 99c download packs - the update itself remains free.

As co-creator Dave Castlenuovo has previously explained, the increase in sales following each update had fallen away over time, forcing the developer to experiment with new revenue streams to keep supporting the game.

The good news for developers thinking about a similar approach is that, so far, it's been successful.

Castlenuovo says even though new Pocket God sales dropped due to the OS 3.0 restriction, overall, revenue increased.

This revenue comes more quickly too as those users who want to get their hands on the optional content - in this case the opportunity to reskinning the game's T-Rex - do so as soon as the update is released.

"New sales decline at a slow rate while the DLC has a huge spike when the update comes out but experience a rapid decline," he says.

Stripping out this DLC spike, a week after the release of the 25th update, Castlenuovo says 27 percent of new revenue from Pocket God came from the sale of the T-Rex pack.

"I'm happy. It's worked out really well for us," he says, explaining all future Pocket God updates will remain free and be supported with optional 99c packs.

"We have to keep pushing out DLC updates to keep revenue at the same point as before we went 3.0-only," he argues out.

The 27th update will feature a Halloween-themed reskin.
