License Plate Game Games On The Go Ages 4 and up. On their cards, players write letters from the license plates of passing cars. As the cards fill up, players score points for every three letter word that they create. The strategy is in deciding where on the card to put your letters to maximize your ability to create words. (letters can not be moved once placed). Everyone works with the same letters that drive by, so this strategy is the only thing that separates the winner from the rest.
