SAMPLE GAME

MasterMind's Answer:

4324

Guess #1. 1234 P A A

P: ONE of your digits is in the answer AND in the correct position (the last 4)
AA: TWO of your digits are in the answer, but NOT in correct positions (2 and 3).

Guess #2. 1111

If you see no "P" or "A" indicators it means than none of the digits in your guess are in the answer.

Guess #3. 2344 P P A A

PP: TWO of your digits are in the answer AND in the correct positions (3 and the last 4)
AA: TWO of your digits are in the answer, but NOT in correct positions (the first 4 and 2)

Guess #4. 2443 A A A A

FOUR As: ALL FOUR of your digits are in the answer, but NONE are in the correct positions.

Guess #5. 4324 P P P P

PPPP! FOUR exact matches! You WIN!!
