RotAtoR is an arcade game where you control a ball that you have to get across a cylinder full of obstacles. To do that you can rotate solely to the right. Like this you have to try to get as far as you can manage.
The controls in RotAtoR are very simple: just tap the screen to rotate right. This is the only thing to do: rotate rightward to get across the obstacles that appear in your path, which won't be few.
As is standard for Ketchapp games, as you play you can get coins, which you can then use to get more balls. You can unlock dozens of different balls to play with, although they won't give you any benefits.
RotAtoR is a simple and direct arcade game offering a fun game experience without needing complicated graphics or controls.
