Through an acquaintance I've heard of this game, pin and further informed me. We have (10.7) paid to our children this pin with games at Christmas and had a rest !!! No disputes, who's off or whether it has been cheated: The pen will announce which player is the train and are accurate and understandable instructions. Really suitable for children! We recommend to all parents to make sure that the pin after the game really (!!!) is off. He is also probably from himself, but the consumption of the batteries can be kept within limits (for environmental reasons ;-)!)
