# Play 3 digit lock puzzle ONLINE

1. Mark forbidden digits. Any clue that says “Nothing is correct” eliminates all 3 digits from the code. If you have a printed copy of the Crack the code game, cross out these numbers in all the hints.
2. Collect “in-code” digits. Clues that say “One number is correct …” or “Two numbers are correct …” tell you which digits must appear in the code (but watch their positions!).
3. Build position rules.
   • Right place ⇒ that digit is fixed in that position.
   • Wrong place ⇒ that digit cannot be in that position.
4. Use the 2-correct-wrong-place clue. It gives you two exact digits of the code and forbids their shown positions.
5. Test candidates. Try only 3-digit combinations using the allowed digits and positions. Each candidate must satisfy all clues simultaneously.

# Example of Numeric Lock Puzzle

Suppose the clues are:

• 618 – One number is correct and in the right place
• 463 – One number is correct but in the wrong place
• 459 – Two numbers are correct but in the wrong place
• 286 – Nothing is correct
• 398 – One number is correct but in the wrong place

Crack the lock code puzzle: step by step

Step 1: From 286, we know that 2, 8, and 6 are not in the code because nothing is correct.

Step 2: From 618, one number is correct and in the right place. Since 6 and 8 are impossible, the correct digit must be 1, and it is in the middle.

Step 3: From 463, one number is correct but in the wrong place. Since 6 is impossible, the correct digit must be either 4 or 3.

Step 4: From 398, one number is correct but in the wrong place. Since 8 is impossible, the correct digit must be either 3 or 9.

Step 5: From 459, two numbers are correct but in the wrong place. This helps us decide which digits belong in the code.

Step 6: Test digit 3. In clue 463, 3 would be in the wrong place, so it cannot be third. In clue 398, 3 would also be in the wrong place, so it cannot be first. That would force 3 into the middle, but the middle is already 1. So 3 is not in the code.

Step 7: That means 4 is in the code from clue 463, and 9 is in the code from clue 398.

Step 8: From 459, both correct digits are in the wrong place. So 4 is not first, and 9 is not third.

Step 9: We already know 1 is in the middle. So 9 must be first, and 4 must be third.

Therefore, the secret code is 914.
