# Week 14: Guess the rule – math game

One of my hobbies is to take completely non-math related games and modify them for classes. I don’t know what to call this game, it is probably a variation of “psychiatrist” or something, but here is how it goes:

• In a group of at least 4 players, ask one player to leave the room and go out of earshot.
• Tell this person that when they come back they can ask as many questions as they would like to figure out the rule.
• Next, the remaining group creates a rule that answers must follow.
• This can be a logical rule
• always lie
• truth then lie then truth
• always tell the truth
• This can be a number of words rule
• always answer in two words,
• anwer in one, then two, then three words
• This can be a sequence rule
• include the next number of the fibonacci sequence in your answer (A1- I had one good fish, A2 – One reason I don’t like questions, A3 – Two of a kind, A4 – I really only like tricycles in threes, etc.)
• This can be a sound pattern rule (like syllables, rhymes, etc)
• Or whatever crazy rule your class/group comes up with.
• once the rule is guessed or the player gives up, play again!
