Hello how may I help you? i need help with rules of games I can help, what game did you have questions on? are you familiar with tag? Yes, I am how to pick first person to be it? The first person who is it, is the first person who actually asks a form of the question"who is it" are you sure? That is the primary rule for tag, however a second selectin done in some regions is a counting game such as "eeney meeney miney mo" thanks Glad to help
