A Game: Pico, Fermi, Bagel
... The the game begins with one person secretly choosing a number with no repeated digits. We will start with a three digit number. Then others attempt to guess the number, and the one who chose the number responds to each guess as follows: • If the guess has no numbers correct, they respond: "Bagel." ...
