Like Tetris? Try CubX. CubX is a new concept of Tetris. It is a puzzle game that employs a unique spin on the game of Tetris. Instead of controlling the blocks and where they fall, you instead control the platform that they fall on. Blocks can come from both the bottom and the top and you can engage in various game modes to challenge yourself. It’s a bit difficult at first but quite enjoyable once you get used to it. It’s also totally free with no in-app purchases. - IOS: https://itunes.apple.com/app/id954868611 - Android: http://play.google.com/store/apps/details?id=com.tnt.cubx Have a look at this video to make an idea on the gameplay: The best way to master CubX is to hold the device as a joystick and to play with the thumbs (not with the index fingers).
