Each player picks a secret word. Do not say it out loud. Every time that word is used, do something unusual - put your hands up, clap your hands, or snap your fingers - until that word is used again. Do this until everyone figures out what your secret word is.
The first player says a letter. The next person adds a letter, attempting to spell a word. For example, the beginning of a round might sound like this: "E." "N." "G." "A." The one saying the final letter of a word more than three letters long loses. A speller can be "challenged" if the next player doubts that a real word is being spelled. The speller loses if a word cannot be spelled. The loser of each round gets a letter of G-H-O-S-T. The first to lose five times is out of the game.
