Analysis
Did you manage to crack the code? Don’t worry if you didn’t—it’s completely normal, especially if this is your first time with this kind of puzzle. To help you get the hang of these puzzles, here’s a quick guide on how you can work through it and find the answer:
Let’s begin with Clue #2. Since 6, 5, 0, and 7 are not correct and are missing from the code, we can eliminate them from any clues that include them.
Next, let’s focus on Clue #1 and Clue #4. From these clues, we can deduce that 2 is not in our mystery code because if it were, it would have been in the correct position in Clue #4. So, as we did with 6, 5, 0, and 7, we will eliminate all instances of 2.
This leaves us with 1 in Clue #1, indicating that our first mystery code number is 1 and it is in the last position. Thus, we should have something like this: XXX1.
In Clue #5, we are left with 8 and 4 (after eliminating 2 and 5 as per our previous deductions).
Let’s turn our attention to Clue #4. We have 9 and 8 here (after eliminating 2 and 5 as per our previous deductions).
Since we know that 8 is in our mystery code from Clue #5, it is apparent that 9 is missing, so we will eliminate 9 from every clue it appears in.
Now let’s try to figure out the position of 8. From Clue #4 and Clue #5, it is apparent that 8 is neither in the first nor the third position, which means its correct position is the second. We have already established that the last digit is 1. So, 8 must be the second digit.
To this end, we have something like this: X8X1.
In Clue #3, we have 1 and 3 as the remaining correct numbers after eliminating 9 and 7. Since 3 occupies the third position, which is incorrect according to this clue, and positions 2 and 4 are already occupied (i.e., X8X1), it means that 3 must be in the first position.
So, we have something like this: 38X1.
The only number that we haven’t eliminated so far is 4, so it automatically occupies the third position. Thus, we have cracked the code: 3841.
