Question

Using the 7 guesses and their feedback shown below, deduce the secret 4-peg code. The available digits are: 1, 2, 3, 4, 5, 6.

Rules

• The secret code has exactly 4 positions.
• Available digits: 1, 2, 3, 4, 5, 6. Repetition is allowed.
• Black peg (●): correct color/digit in the correct position.
• White peg (○): correct color/digit but in the wrong position.
• The number of pegs does not indicate WHICH positions are correct.

Hint

Use process of elimination: identify which colors are in the code, then find their positions.
