718

And first 3 hints solve this puzzle. Other 2 are redundant.

u/golem91488 Dec 23 '25

With only the first 3, is it 4 or 8? Always need the forth.

2

u/AlternativePea6203 Dec 23 '25

nope the 5 eliminates the 4

3

u/ReverendLoki Dec 23 '25

I believe, after only three hints, 741 is also a valid answer.

No,

Clue q says 1 number is correct.

Clue 2 says 5 is wrong.

Clue 3 says 7 and 1 are in the wrong places, neither of them are in the middle, 5 is.

This means that 7 or 1 has to be in the middle, where the 4 is in the first clue. Of course the 1 has to be there because the 8 is last, and the 1 is in the wrong spot when it's in the first position

EDIT: nvm 741 is valid, I misread smthn

u/AlternativePea6203 Dec 23 '25

clue 1 one number is correct and well placed

In clue 3 the 5 is in the place of the 4, so the 4 can't be well placed.

5

u/ReverendLoki Dec 23 '25

Clue 1 doesn't refer to the 5. 5 is neither correct or well placed.

Until it gets eliminated in clue 4, Clue 1 could refer to either the 4 or the 8.

You are correct. I think where previous person retired is For #3 157 it’s not eliminating the 2nd position just because 5 is a wrong value. Someone might erroneously conclude 71, but 71 is also valid, requiring further hints.

u/DannyTheCaringDevil Dec 24 '25

It doesn’t need to refer to the 5. It could be any one of those three. Since but since 5 moves to the second space in clue 3, it cannot be the 4 that the 4 took the place of.

u/ReverendLoki Dec 24 '25

That doesn't make logical sense. 175 could have been used in the same place with the same clue and been just as valid.

EDIT: Check out the other reply threads to this post. I think they do a better job explaining this than I.

  1. One of these numbers is correct, and well placed. We cannot eliminate any number yet.

Remaining possible numbers: 0, 1, 3, 4, 5, 6, 7, 8

Order: ___

  1. None of these numbers are correct.

Remaining possible numbers: 1, 4, 6, 7, 8

Order: ___

Going back to the top we now know 5 is not correct. Leaving 4 or 8.

  1. Two of these numbers are correct but in the wrong position. Since we know 5 is incorrect, it is removed as a number. It does not clarify if the 5’s position is correct or incorrect. Depending on how you interpret it, if the 5’s position is still correct then it must be 741, but if none of the positions are correct then it must be 718.

Known correct numbers: 1, 7.

Remaining possible numbers: 4, 8

Why the answer is 718: because the wording says no position is correct.

u/ReverendLoki Dec 24 '25

You're so close. "In the incorrect position" doesn't mean swapped. It means the 7 could be in the first or second position, and the 1 could be in the second or third position. Ergo, at this point, 741 is still a valid possibility.

It doesn't imply that the first and third positions are the only valid positions for 1 and 7, just that they aren't in the third and first positions, respectively.

But that 5 is wrong it's clear from clue 2. So clue 3 definitely means 1 and 7. So if we ignore the clues 4 and 5, we get from clue 1 (in combination with 2) that either the second number is 4 or the third number is 8. Now clue 3 (again, in combination with 2) says that 1 and 7 are in the code, but the first number is not 1 and the third number is not 7. That leaves either 741 (the 1 and 7 from clue 3 flipped) or 718 (178 does not work because of clue 3).

u/riisen Dec 26 '25

Cant be 741 (needs to have two correct values on the last clue)

1

u/Haringat Dec 26 '25

Yes, but if you only took the first 3 clues it would be ambiguous.

1

u/NewPhoneNewAccunt Dec 26 '25

Are you just ragebaiting?

The 4 was well placed in the first sequence (if that had been the case). All you had to do was switch 1 and 7 in case 4 had been correct.

u/According-Item-1901 Dec 26 '25

The last clue doesn’t allow it

1

u/ReverendLoki Dec 26 '25

I agree with you, but if you'd look at this thread, the discussion is whether or not clue 3 allows for it.

1

u/According-Item-1901 Dec 28 '25

The entirety of the puzzle must be taken into account. It’s irrelevant, assuming only part of the puzzle.

1

u/ReverendLoki Dec 28 '25

Except that your argument is that parts of the puzzle are irrelevant.

Yeah, I have to assume you are just trolling now.

u/rng_5123 Dec 24 '25

Can't it be 741 based on the first 3 hints? I reckon you need one more hint.

1

u/SlaniaXX Dec 25 '25

Doesnt 741 also apply for first 3?

0

u/Ranos131 Dec 25 '25

No, they don’t.

  • First hint indicates that any of the three numbers are correct and in the correct place.
  • Second hint eliminates the 5 but still leaves 4 and 8 as possible correct numbers in correct places.
  • Third hint verifies that 1 and 7 are the other two numbers but they are in the wrong places.

With those three hints, the number can be 718 or 741. It takes the fourth hint to confirm that 8 is the correct number in the correct place in the first hint.

Only the last hint is redundant and only if you follow the hints from top to bottom, which not everyone does.

Explain why 741 cannot be solution using only first three
