Tap roller

Tap Roller is an original Android game that tests your smarts and agility of your fingers. You will be presented with a round room with balls on the screen and your goal is to get the balls to the portal that leads to the next level. To do this, you must rotate the room in all directions and make sure the balls don't get stuck in a dead end or hit any obstacles or traps. The game features over 50 unique balls, many levels, a leaderboard and achievements, support for 7 languages, and a one-tap control system.
