Hints & Clues

  • Think Simple, Not Hard: The answer is easier than you think — trust your gut and don’t overcomplicate it!
  • Process of Elimination: Knowing which numbers aren’t in the answer will get you halfway there. Which numbers are eliminated, and which numbers aren’t?

How To Solve This Puzzle

Start by reading through each line carefully. The last clue tells you which numbers are not in the answer, which is a great start to figuring out which numbers are. From there, you can eliminate numbers from the rest of the codes. So, knowing there’s no 2, 1, or 7 in the final answer:

  • 378 — Only 1 of these numbers are correct and you know it’s not 7.
  • 931 — You know two of these are correct, and it’s not 1. So, 3 and 9 will be somewhere in the answer.
  • 423 — You already know that 3 is in the answer, and the hint implies that only one of the final digits is in this code. So, 3 is the last digit in the code.
  • 165 — You know there’s no 1, so you’re left with 5 or 6.
