Fun roadtrip games: HORSE

It's a fun word game. One player starts with any letter. Then you alternate turns. You must have a word in mind each time you add a letter, but you do NOT want to end a word. Here's a sample:

Player 1: d
Player 2: du
Player 1: dut
(Player 1 is thinking of "duty," and thinks Player 2 will now have to finish the word with a "y.")

Player 2: duti
(Player 2 was too clever, and is going for "dutiful," which player 1 will have to end.)

Player 1: dutie
(Ah! Player 1 is thinking of "duties," which Player 2 will have to end.)

Player 2: duties. Ends word, gets an H. The next time she loses, she gets an O. First one to spell HORSE loses.

If you say a letter and are challenged, you have to come up with a word, or you get the HORSE letter. For example, if your opponent says "S" and you say "J," she can challenge you and if you don't have a word that begins "SJ," you get a letter.
