Pets vs Orcs is the first mobile Supercell game released in January 2012. It was taken of the stores a month later. BUT I can say that the game is well archived and you can try it out yourself. Currently only the Android version has been found though. And you’ll need an older device in order to start the game properly.

(Almost) everything regarding the game is allowed here. I’ll update the Archive and this community once I find the iOS version (if there even is one).
