The creator of Happy Wheels iOS app has yet to announce a solid release date for the upcoming mobile iteration of the game. 

The Happy Wheels iOS app was initially expected to arrive before the summer season of 2013 ends. However, the year is about to end already, and apparently, the highly-anticipated mobile version of the ragdoll-physics based game is still not available.

According to the latest update from Fancy Force (@fancyforce) regarding the upcoming mobile version, via Twitter, Happy Wheels iOS app will most likely have a 12+ rating, based on the content and category of the game. The actual tweet is shown below:

@MisterWhite_548 It will likely be 12+ based on it's content/category.

Moreover, the Happy Wheels iOS app is expected to run on various Apple devices. A tweet from Fancy Force reads, "It should run on retina devices as well as the iPad Mini. So 4th & up (we hope, 4S might be the recommended min)."

There will also be a basic level editor for the Happy Wheels iOS app. Check out another tweet from Fancy Force, answering a query from a fan of the game.

@AutopsyX I mean the iOS editor will be more basic (less stuff initially), but we will try and bring it closer to the online editor in time.

As for more information regarding Happy Wheels iOS app, the iPhone version was first shown during the PAX East 2013 event, according to the game's Wikia page. The app version of Happy Wheels will have a similar version from the online edition. However, one of the main differences is the controls. Since iOS devices do not have keyboards, the characters from Happy Wheels will be controlled using on-screen buttons

Moreover, the Happy Wheels iOS app, set to run at 60 fps, will have Game Center and iCade support.

Moreover, the Android version for Happy Wheels will be in development soon after the release of the iOS app.

An update to the original version of Happy Wheels is also expected to arrive soon. And accordingly, a new character will arrive alongside the update.

Stay updated for more details to emerge regarding the online and upcoming iOS version of Happy Wheels.
