Participants interacted with the game by saying the word "Pix" to perform game-related actions. Prizes included T-shirts and $10 U.S. savings bonds. They could double their prize or win a bonus prize (such as advance tickets to see upcoming films) by guessing a "Magic Word" (originally common everyday words, later in the last two years one of the 50 U.S. states). For a chance at playing, children could send a postcard with their name, address, and phone number to "TV Pixxx".
