Crack the Code Puzzle – Can You Solve This Numeric Lock Riddle?

Puzzles and riddles have always been a fun way to challenge the brain, and one of the most popular types you’ll find online today is the “crack the code” puzzle. These mind teasers usually involve a numeric lock with hidden rules, and the goal is to figure out the correct 3-digit or 4-digit code using the hints provided. If you love logic challenges, then this puzzle will definitely catch your attention

In the image above, we are given a numeric lock with a 3-digit key. Several clues are provided, and each one tells us which numbers are correct, which are in the right place, and which are not part of the code at all. Let’s take a closer look at the clues:

682 → One number is correct and well placed.

614 → One number is correct but wrongly placed.

206 → Two numbers are correct but wrongly placed.

738 → Nothing is correct.

780 → One number is correct but wrongly placed.

The challenge is to use logical reasoning to eliminate the wrong numbers and test the possibilities until you arrive at the correct code. Unlike random guessing, these puzzles are designed to strengthen critical thinking, problem-solving skills, and attention to detail.

So how do you solve it? First, notice from clue 738 that digits 7, 3, and 8 are not in the code. That means every other clue must be solved without using those numbers. From clue 206, we know that 0 and 2 are part of the code but not in the right place. From clue 682, since 2 is confirmed to be part of the code but wrongly placed earlier, the correct well-placed number must be 6. By carefully comparing all the hints, you’ll eventually arrive at the hidden code: 042.

This type of logic riddle is great for anyone who loves Sudoku, escape room games, or math puzzles. Not only do they provide entertainment, but they also keep the mind sharp.
