The program presented below will play the game of bagels (sometimes known as Mastermind) on the HP-65. It was written by John Rausch and appeared in the V2N3P35 issue of PPC Journal (March 1975). Thanks to John wherever he is today!

Try to guess the three digit number generated by the HP-65. All three digits are different. After the guess, you will be given a clue as to how well you've done in the form of A.B, where A is the number of digits you have guessed correctly in their correct position and B is the number of digits you have guessed but in the wrong position. When you guess the number, the display will show the number of guesses you took as a negative number.

If you get the number in 1-3 guesses, count yourself lucky. 4-5 guesses is excellent. 6-9 guesses is average. 10-14 guesses means you aren't trying. 15 and above means you should try another game!

**Instructions: **

1) Load the program into the calculator and change back to RUN mode.

2) Enter the initial decimal seed and press STO 6.

3) Start the game by pressing A.

4) Enter your guess and press B. The display will show a clue as
described above.

5) For a new game, go to step 3.
