How to Play: Mastermind Code Breaker

This challenge tests your deductive reasoning and logical hypothesis testing. The goal is to crack the hidden four-color code in 10 moves or fewer.

Start: Press "Start New Game". The computer generates a secret code of four colors (colors may repeat).
Guess: Click on the four empty peg slots to select colors from the color selector below.
Submit: Once all four slots are filled, press "Submit Guess".
Deduce: The system will provide feedback using black and white pins for your guess. Use this information for your next move.

Feedback Key

Black Pin: Indicates one color is correct and in the correct position.

White Pin: Indicates one color is correct but in the wrong position.

*No Pin:* The color is not part of the secret code.

💡 Tip: The order of the feedback pins does *not* correspond to the order of the pegs in your guess. You must use pure logic to deduce the correct placement.
