A unscramble the letters game, letterHEAD includes over 300 cards with mixed-up letters on the backs of each. During game play, a card is turned over and the letters are revealed. For example, all players will see a card with these letters, 'RUNTYCE'. The first player has 30-seconds to attempt to unscramble the letters to make a word. If he/she is unsuccessful, then it is up for grabs. If successful, then he/she would have spouted out, 'century'. The player would move ahead and maintain turn. letterHEAD's cards are, for the most part, very challenging. If you a really good at this game, then you can get the Genius cards, available through Enterfection Games. - BoardGameGeek
