What's GNU? (2004)

From the manufacturer:

The object of the game is to spell more three-letter words than the other players. Word-Starter cards which have one letter and two blanks are spread out for everyone to see. Players slide the Letter Getter to reveal two letter tiles. At the same time, players must look at these tiles and try to make three-letter words by filling in the blanks on the Word-Starter cards. The player with the most three-letter words when all the tiles run out wins.
