the game will ask you two questions, the first is how many times the cup will swap, i recommend putting 50 to 100 for this one. the second is how fast it does this in seconds, i recommend 0.5 for this one. after that the game will present which cup the ball is in, and you'll have to keep an eye on which cup that is, then when it finishes click on the cup you think it was. if you're right yippee if you're wrong oh well
