What did Reddit users say about this brain teaser?
832. Box 1 tells us that 6,4,5 are not in the correct solution anywhere. Box 2 tells us that 8 is in the final solution, since we know 4 and 5 aren't (from Box 1) but it's not in the middle position. Box 3 tells us that 8 is in the first position since we established it is in the final solution but not in the 2nd position from Box 2, and also not in the 3rd position from this box. We then also know that either 7 or 2 is in the final solution, with 2 being in the final position (because it isn't in the middle one, and we now know 8 is in the first position, or 7 could be in either 2nd or 3rd position. So it's either 87?, 8? 7, or 8? 2. Box 4 - We already know from Box 1 that 6 isn't in the final solution, so we now know 3 is in the final solution somewhere. Combined with our determination after Box 3, we can fill in the question mark, and at this point, our final options are 873, 837, or 832. Box 5 - We already know that 8 and 3 are in the final solution, and we know 8 is in the first position, so 3 must be in the wrong position. We also now know 7 isn't in the final solution. So we move 3 to the middle position, and revert to box 3 to pick up the 2 for the last spot. So, 832,” wrote a Reddit user.

“I got 837. I'm confused why everyone is saying 832? At what point do you guys work out that 7 can't be in the final? It just seems to appear randomly in people's work. Never mind, I'm a dumba** and made a mistake reading the final box. It's two are correct, but one is in the wrong place,” added another.
“I have been at this for hours, but now I am even more confused,” expressed a third.
