Yes, we played it last time we were there. They'll make an announcement over the loudspeaker when it's about to start, and I think it starts like an hour before the show. They'll announce the instructions for how to connect to the special Paradise Pier wifi over the loudspeaker, or at least, they did when we were there. The instructions show up on the screen. It's basically a game of Simon, if you're familiar with it, where the colors light up on the wheel and you have to push them in the same order on the phone. The winner gets to control the lights for 30 seconds and they have like five rounds or so. It's a great way to pass the time! We passed the phone around so everyone in our group got to play a round. I don't think you need a data plan to play.
