The Google Play Store more than doubled its total game revenue year-on-year from Q2 2013 to Q2 2014, with the iOS App Store also seeing game revenues rise by over 70 per cent.

The figures come from App Annie and IDCs quarterly Portable Gaming Report, which also showed that Androids share of the installed base grew 8.4 per cent, hitting 70 per cent, while iOS shrunk slightly, but 1.9 per cent.

Games represented around 40 per cent of downloads for both of the dominant app stores, but spending on games rose for Android, with games making up almost 90 per cent of consumer spending in Q2 2014. Games spending held steady for iOS, accounting for approximately 75 per cent of app store revenue.

There were regional differences between the two operating platforms too, with iOS seeing game spending grow most in the Asia-Pacific region, while Google Play made its largest gains in Western Europe.

Looking at popular games, Clash of Clans, Puzzle & Dragons and Candy Crush Saga both made up the top three for iOS and Android (although in different orders), with Game of War – Fire Age and Hay Day making up the rest of the iOS Top Five, and Monster Strike and The World of Mystic Wiz taking the four and five spots for Android.
