Going in circles can actually be quite fun and addictive! In Electric you have to wait your turn and then tap your phone as soon as your target is ahead of you. The spinning ball makes it quite difficult, but awesome at the same time.
When you hit a plus sign, the speed will increase. When you hit a minus sign, it decreases. So go ahead, give it a try, and see if you can spin your head around this great little time consumer!
