Shake it, but do yourself a favor and don't twist or shout. It might cause a scene. Of course, you shaking your android device like a mad man may cause somewhat of a scene anyway, that is how it has to be with you play Salla Salla for Android. Basically you choose a 15, 30, or 60 minute time frame and shake as much as you can. The more you shake in that time the higher your score.
You can open an account to play, or if you would rather not you can play as a guest or login with Facebook. Share your score to the Swarm leaderboards to see how your shake stacks next to shakers from around the world. Can you shake your "thang" better than anyone else? There is only one way to find out.
Shake it, don't break it, cause then your phone won't make it. Shaking is a great stress reliever, but hold on tight and don't get carried away. Others may think you've lost your marbles, or at least that they have come a little loose with all the shaking. If you start getting strange looks, just move away slowly to a private place and shake to your heart's content. It's worth it.
