Electronic Arts is shutting down its Tetris games for mobile devices, including both Tetris and Tetris Blitz.
An announcement on the iOS store page (reaffirmed to GamesIndustry.biz by EA) for Tetris Blitz confirms the games will soon be removed, and in fact already appear to have been taken down from Google Play.
