Secret Code Test

What Is the Secret Code Test?

The Secret Code Test is a code-breaking challenge where you use feedback from previous guesses to figure out a hidden number sequence. Tasks based on games such as Mastermind have been studied as examples of logical problem-solving and strategic reasoning. See research on Mastermind strategies.

How Does the Test Work?

You make a guess and receive clues showing which numbers are correct and whether they are in the right position. Use those clues to narrow down the possibilities and find the secret code.

In this test, the code becomes more difficult as you progress. Your score is based on how many levels you successfully complete in a row.

What Does Your Score Mean?

Your result is your longest successful streak. A higher streak means you were able to solve more consecutive codes.

Because this is a custom online test, there is no reliable worldwide average or fixed percentile system. Your score is most useful when comparing your own results across repeated attempts.

What Can Affect Your Result?

• Strategy: Good use of previous clues can reduce unnecessary guesses.
• Working memory: You need to keep track of information from earlier guesses.
• Attention: Distractions can make it easier to miss or misread clues.
• Practice: Familiarity with the rules can help you develop a better strategy.
