SEGA has updated Sonic Dash on iPhone and iPad in order to address some issues reported by gamers worldwide, as well as to add new features and enhancements.
Sonic Dash version 1.1.2 adds bigger and better rewards in the Sonic Dash Daily Challenge, improves load times on some devices, and (specifically) improves performance on fourth-gen iPod touch players and the iPhone 4.
You can now download other SEGA titles in the 'More Games' browser and you’ll get better Game Center integration as well. Lastly, the 1.1.2 update fixes a rare issue that could delete game progress when playing the Daily Challenge.
Sonic Dash works with iPhone 3GS, iPhone 4, iPhone 4S, iPhone 5, iPod touch (3rd generation), iPod touch (4th generation), iPod touch (5th generation) and iPad. It requires iOS 5.0 or later and is natively supported on 4-inch screens. The game continues to be available as a free download.
