First up, you'll want to leave your Dice under a bright light for a while. This isn't mandatory, but you'll get the most glow if you do. Then, roll both dice at once. One will tell you or your partner which position you'll be in, and the other will tell you where that position will be assumed. It's easy, it's sexy, and you can leave the lights off!
