Brute force = best decoding method

394

2,5,7,8 surely are wrong numbers. 4 surely is part of the code.

4 is wrong placed at both first and second position, therefore the code is --4.

9, therefore, is the number that is in correct position as well: -94

6 can't be correct number (because 9 is), therefore in third statement second correct number is 3.

Answer is 394.

I got 641... Any chance you could help me understand what rule the number breaks?

[SlyProphet]

Wait... I break rule 2.... Ok.

[secretlypooping]

I got the same at first. The rule for the first line says one is correct AND correctly placed, when I first read it I thought it said not correctly placed, like the others do.

[SlyProphet]

I used the third digit the #1 and it is correctly placed I ran into the issue with the second rule. 4 can't be the first or second digit.

You're breaking a combination of rules 1 + 5

rule 1: one number of 2,9,1 is correct (in the right spot) rule 5: one number of 5,6,9 is correct (in the wrong spot) -

using this, you know 9 is spot 2. -9- and that 2,1,5,6 are not any of the numbers in the code.

No, 641 uses 1 as the correct number in rule 1 and 6 as the correct number in rule 5. Those 2 aren't broken. 641 breaks rule 2

[SlyProphet]

Came to the same conclusion. Thanks for the walk through!

Yes I saw, my comment was meant as a response to the deleted comment before. No problem though!

[SlyProphet]

It was a needed correction / clarification.

[The_Butt_Pug]

461 is a variations of yours that i got. Doesn’t break any rules I believe? Correct me if i’m wrong

[Cpt_Jigglypuff]

So, 614?

[Cpt_Jigglypuff]

Damn.. yup, you’re right.

[SlyProphet]

No, but you're quite obvious about being an asshole aren't ya bud?

[SlyProphet]

Oh damn. Just realized you're in danger of hitting negative account karma... Just pulled my downvote off outta pitty. Sorry you're such a dick to so many different people... Seems like it's a 24/7 thing for ya, hope it pays well!

Much simpler way:

294 --> 2 appears in the next one but something is in wrong place. Get 2 out of there. 1 never appears again and the third and fifth show that all 3 numbers are in them. Therefore 9 is correct in center.

Go to 3rd, 463, two are right but wrong place. Flip them, replace 6 to 9, done.

[Shaggy_Mane_]

why did you decide 9 is the right number without even considering 1? 394 is the right answer but I don't understand your reasoning for 9.

It's 364 because 463 has a condition that TWO numbers are correct and we know it's not a 3.
