its called see low. you roll one die each to see who goes first, lowest num goes first. when you roll, you roll all 3 dice at once until u get two dice that say the same number- and the third one is your number. so if you roll 2, 2, 4- then 4 is your number and the next person tries to beat you. triples or trips meaning 1,1,1 or 2,2,2 etc beat any regular roll. 123 is automatic lose, 456 is automatic win..... so you keep rolling until you get two dice of the same number and a third with another number, or until you get trips, 123 or 456
