The top 200 iOS games still bring in more. According to Distimo, that figure was $18 million a day in November But that is a much smaller increase from the $15 daily that those top 200 iOS games brought into the coffers daily during November 2012. So while the leading iOS games saw their daily take increase a decent 20% a day over the last year, Android's top games saw their income soar 342% over the same time period.
Most of the gain for Android came from gamers playing in Japan and South Korea. In those two countries, money spent on games for Android out numbered the money spent on iOS games. In south Korea, Android revenue for these titles soared an unfathomable 759%
Most of the revenue coming in for either platform, is from freemium games. These games are free to download and install, but in-app purchases of special powers, or extra lives are usually required to make it to the higher levels. A good example of that is Candy Crush Saga, one of the most popular games, which is free to install on your phone or tablet. But when you get frustrated trying to get past a certain level, shelling out some cash can help grease the wheels.
