Can you crack this code?

I am getting 062.

1) if 7, 3 and 8 as numbers are out then that means that in '780' 0 is correct but incorrectly placed. So that means that it can be in either the 1st or 2nd slot.
2) If in '206' two are correct but wrong placed, then that means that zero can not be in the 2nd slot either. So that MUST mean it is in the 1st.

+1 y

3) If in '682' one is correct and placed correctly then it can not be 6, because the 1st slot is taken. That means that 2 takes up the 3rd slot.
4) That leaves the middle slot for 6

042

1st box says 6, 8 or 2. 8 is eliminated because 4th box says so.

5th box confirms that 0 is also in the answer as 7 & 8 are eliminated by the 4th box.

If we believe that 6 is correct (from the 1st box), then it becomes wrong as per the 2nd box. It means that the correct number is 2 and its place is last (right).

0 is correct and the place is first (left), confirmed from the third box

Coming to the 2nd box again. The answer is between 1 and 4. It must be 4 because it is located at the last (right) place and it is said that the correct number is at the wrong place.

Then the number is... 042

Correct. Ignore updates.

[YourFutureEx]

No. They are the permanent proof.

We have numbers 0 1 2 3 4 6 7 8 to choose from.

738 nothing correct implies that the code contains 0 by 780 containing one correct mis-placed number..
Remaining choice 0 1 2 4 6

The correct and wellplaced number in 682 cannot be 6, because, then it would be correct in 614, but misplaced, contradiction. Therefore the code contains either a 1 or 4.

But then then the correct wellplaced number in 682 has to be 2. Therefore 20 are correct in 206 and the code does not contain 6.
Remaining choice 0 1 2 4 and we know the code is x x 2.

It will then be either 012 or 042. I'll let you work the details. [042 is correct answer, why?]

[ThisDudeHere]

042 is correct because we conluded that 2 has to be in o the right, so xx2. We concluded that 0 was correct, but if '780' said that it was wrong placed at the right, whereas '206' implied that it was wrongplaced in the middle, leaving only the left. Which meant 0x2.
The only lead as to which is the middle one comes from '614' - out of these, only one is correct but wrong placed. It can not be 6 at the left, because it'd then contradict iself with '682' which implies that only one (2) is correct and well placed.

That leaves just the number 4.

[sp33d]

well done :) You may also that 1 will be omitted, because it can only be in the middle, as you correctly deduced that 0x2 is the code. But then 1 would be well-placed, contradiction. Therefore 042 is the only possibility.

[sp33d]

I'm inspired by your post to put up a few logic puzzles here :D

[ThisDudeHere]

Invite me if you do :D

[Schrodingerscat]

1. Box 4 - Nothing is correct. So none of 7,3,8.
2. Box 5 - One correct but wrongly placed. We know from Box 3 that 7,8 isn't there. So 0 must be there. But it is wrongly placed. So it must belong to 1st or second place.
3. Box 3 - 2 correct numbers but wrongly placed. We know 0 is there. But it is in 2nd place now. So it is now fixed in first place. Now 2 possible numbers are 2 and 6.
4. Box 2 - one number is correct and wrongly placed. So 2, 6, 1, 4 are new possibilities.
5. Box 1 - 6 is eliminated now. And 2 fixed at last place.
6. Now we got 1 and 4. So 4 is the answer
Hence, 042.

[ThisDudeHere]

Correct, please ignore updates.

[Nicole9356]

042 or 062 I'm not sure

[ThisDudeHere]

042 is correct.

[goaded]

042

6 isn't in it, because it can't be correct and both rightly and wrongly placed in hints 1 and 2.
2 and 0 must be in it because of hint 3 and the above, the other digit is 1 or 4 from hint 2.
8 is not in it because of hint 4, neither are 3 or 7.
2 is the last digit because it is well placed in hint 1.
0 is the first digit because it is wrongly placed in hints 3 and 5.
The final (middle) digit must be 4, not 1, because 1 would have been well placed in hint 2.

Ta dah!

[ThisDudeHere]

Correct. Ignore updates.

[goaded]

I just noticed that hint 4 isn't needed at all to solve it, 8, 3 and 7 were never in the running.

[helphelpimdying]

042 but that took me like 10 minutes because i refused to look at the comments. hey at least i didn't cheat

[Yumix]

we had that one already a couple weeks ago... just start from the 4th hint, it's really not that complicated

[ThisDudeHere]

Must have missed it.

[FakeName123]

Not really awake - so I will still try. 042.

[max_spy]

how much time did you take to figure it out?

[ThisDudeHere]

I think you're correct, my updates are wrong. '206' implies that only two are correct.

[FakeName123]

@max_spy

3-4 minutes

[FakeName123]

Ok. Just looked at it again. 042 seems to be correct.

1. 738 is wrong meaning all of these numbers aren't involved.
2. 780 means the one correct number is 0, but it needs to be on the first or second spot.
3. 206 has the 0 in it which is correct and once again in the wrong position. Thus the first number of the combination is 0. The other correct one is either 2 or 6.
4. 682 has one number correct and well placed. Since the first number is already known to be 0 it therefore can't be 6. Thus we now have 0x2
5. 614 has the 6 in it which it can't be. Thus it must be 1 or 4. Since it's right number, wrong place and the 1 would be in the right place already it must be 4.

Thus 042

[Anonymous]

either 012 or 042

but ill look more carefully later.

[Opinion Owner]

oops its 042.
012 eliminated itself.

[xellax]

042?

[xellax]

didn't look at the answers i promise :P

[ThisDudeHere]

Correct. Ignore updates.

[Sakura99]

I think it's 042

[ThisDudeHere]

Correct, please ignore updates.

[Anonymous]

At a quick glance I'd say 062 but I might have missed something

[ThisDudeHere]

You have indeed, 6 would be incorrect.

[Opinion Owner]

Ah yes of course, it's 4, the 2 was the correct one from the first

[SuicidalTeen]

I got 120 or something

[SuicidalTeen]

I had it but instantly forgot lol 120 can't be it

[SuicidalTeen]

042 was it lol

[short_guy]

042?

[short_guy]

062 is wrong, I got this answer too but it doesn't correspond to hint 3.

[ThisDudeHere]

I think you're correct, my updates are wrong. '206' implies that only two are correct.

[Thisperson98]

042?

[ThisDudeHere]

I think you're correct, my updates are wrong. '206' implies that only two are correct.

042. I love this.

[Cloudy25]

042 i think

[Cloudy25]

Hell yeah I'm right xD

[max_spy]

you think? I hope you didn't Google it

[Cloudy25]

@max_spy why would I google it? It's not exactly quantum mechanics, I just used the method of elimination. Simple logic will do.

[TyroneTerminator2229]

Is it 042?

[TyroneTerminator2229]

I bet potheads are going to say "dude it's like 420"

[Waffles731]

I'm also going with 062

[ThisDudeHere]

It's not, ignore updates.

[lord_chilled]

610.
Took me about 3 mins wo writing down

[lord_chilled]

Dammit, 042, was the right one.
Should habe written it down amd double checked before jumping the gun

[ThisDudeHere]

I think you're correct, my updates are wrong. '206' implies that only two are correct.

[lord_chilled]

Yeah i was wrong too, at first. Mistakes were made.
If you got any more riddles, invite me when you post them, im a bit rusty and i need to do them more

[Chrysis]

042

Easy.

[max_spy]

smart brain

[Chrysis]

I just have a thing for numbers, lol.

[max_spy]

you should be an accountant xD

[Chrysis]

My thing for languages is bigger. xD

No, really. I'm good at Maths & riddles but that's because I like doing them in my spare time. Like, when I was small I barely played with the toys I had, I counted & sorted them, lol. Still kinda do that today... When waiting for the bus, other people are staring at their phone. I'm counting... things. Like how many lamp posts there are, how many cars are parking nearby. xD'
I'm weird.

[max_spy]

You're weirdly interesting. how's your thinking skills?

[Chrysis]

They have their ups & downs. xD

[Chrysis]

@ ThisDudeHere

You want me to explain it to you? You're doing the same mistake I almost did.

[nimbus24]

042 is the code

[cupidkisses]

the code is 0 4 2
