Galaxy Tab 3 - motion controls

[anon(8030556)]

Hi I am operating a samsung galaxy tab 3 10.1. I have downloaded a game, and it tells me to shake, and turn my tabl....... I know I have seen that option in my tablet for using hand gestures etc. But I cannot find it. I have been reviewing the 10.1 for dummies and still havent'a found it, can anyone tell me where to locate the gestures so that I can shake and turn my device. (obviously not looking in the right titles) thanks you so much.
