Linda taught me this game when I was visiting her in Muskegon. She just called it "the five-letter word game." I thought it needed a name, and Think is as good as any.
Each person thinks of a five-letter word with all five letters different, and writes it down in a hidden spot.
Guess your opponent's word.
The players take turns offering a five-letter word (all letters different), as guesses, and as clue-gathering. If the guess is not the right word, then the opponent tells how many letters are right.
The game is similar to mastermind, but there's no information about where the letters go. (So you could get all five letters right, and still have the wrong word!) It's not a math game, but it is a logic game, and I think logic and math are twins.
I'll share my guesses:
STOMP 0 (No letters right. Great. I can cross all of those off my alphabet where I'm keeping track.)
TRUCK 0 (Now I know 9 letters that aren't in the word.)
Would you have picked other clue words? Do you have enough information from these clues to guarantee any of the letters in the word?
