Very easy once you get in the room. Each staff member's room is a little different, but in general you have to do the same thing. Step into the line, which is usually a river or something. The river keeps you in line and moves you forward as players finish. When it is your turn, walk to homeplate and double click the predictometer (this is the green bat thing that generates a hit - it tells you whether you get a single, double, triple, homerun, or out). If you get a run, walk around the bases to base that the predictometer tells you. Continue around the bases as players take their turns. Once you cross homeplate, there is a teleporter that will take you to another room where you will get a message telling you that you have won a predictometer. If you get an out, there is a teleporter to the right of homeplate that you enter. That's the long, very simple explanation. Hope it helps.
