App Annie has released the February edition of its Index for Games, which highlights the top performing games across the iOS App Store and Google Play.

The report indicates that games dubbed 'Super Casual' - simple, often one-touch experiences in the vein of Flappy Bird - continued to perform well across both app stores in the month of February.

Simplicity wins big

Ketchapp's ZigZag was the star performer on the App Store, rising to the top of the iOS gaming download charts almost immediately after its release in the US, and going on to top the worldwide chart for iOS game downloads in February.

Meanwhile, Crossy Road was the 'Super Casual' game making waves on Google Play, climbing 6 places in February to claim the number 2 spot on the platform's worldwide games download chart for the month.
