Bagels!

I want to introduce you to a game called Bagels, a strategy number guessing game. Here are the three clues:
Pico=one of the digits is correct, but is in the wrong place
Fermi=one of the digits is correct, and is in the correct place
Bagels=none of the digits are correct.

Example:
First player makes up a 3 digit number (727)
Second player guesses: 111
Bagels! None of the numbers are correct
Second player guesses: 222
Fermi! One digit is correct and is in the correct place
Second player guesses: 233
Pico! One digit is correct but is in the wrong place
Second player guesses: 424
Fermi! One digit is correct and is in the correct place
Second player guesses: 525
Fermi! One digit is correct and is in the correct place
Second player guesses: 626
Fermi! One digit is correct and is in the correct place
Second player guesses: 727
Winner!

You can also give combinations of clues, like: Pico Fermi, or double Fermi.

Try it and have fun!
