Question

Using the 6 guesses and their feedback shown below, deduce the secret 4-peg code. The available colors are: Red, Blue, Green, Yellow.

Rules

• The secret code has exactly 4 positions.
• Available colors: Red, Blue, Green, Yellow. 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.
