If you have a Sphero – the Bluetooth-controlled robot ball – then you know just how much fun they can be. If you happen to have more than one Sphero, you're in for a real treat, as you can now operate multiple Spheros from a single device, thanks to a new feature in the app called Multi-Ball.

To use the feature, all you need to do is select each ball individually from the connection screen, hit done, and... that's it. You can now play with all your balls at the same time! Have fun with that.
