Logic and/or math-based puzzles that fit a text or image format are generally allowed. Posts that make sense as a video or website link are allowed with moderator approval, so please ask us first. Generally, videos should promote discussion, and websites should provide features that are useful to solving the puzzle.
Use spoiler tags when posting a hint or solution to a puzzle. Guesses must also be spoiler-tagged. Top level comments are automatically removed unless they include a spoiler tag or start with "Discussion:" or "Question:"
All puzzles should be logic based. Check out /r/riddles for puzzles based on lateral thinking. Jigsaw puzzles are best suited to /r/jigsawpuzzles
Use a descriptive title. Titles should be descriptive, not just "Check out this puzzle" or "Puzzles only geniuses can solve."
Please do not posts puzzles from ongoing contests. If you see a riddle that's part of a contest, please report it.
Credit puzzle creators. If you did not make the puzzle, please try your best to credit the original source. If you are not sure of it, or have personally received the puzzle from someone, please indicate that. This rule applies more to puzzles you found online.

/r/riddles - word-based puzzles that use lateral thinking, rather than logic. Stuff like "What gets wetter as it dries?"
/r/mazes - Visual puzzles where you find a path through the, well, maze.
/r/rebus - Visual puzzles where images are strung together to make a sort of visual pun. Find the phrase the images "spell"
/r/jigsawpuzzles - Jigsaw puzzles. You have a bunch of pieces that fit together to make an image
/r/CrackTheCode - If you solve the puzzles, you could win a key to a game!

I’ve been working on this for weeks and can’t figure it out! The app won’t let me move on until I solve it. Please help! Thanks.
Rules:
so sorry to bombard everyone by constantly asking for tips and answers, and quite sad that I can’t find much online about different techniques! I don’t know if there’s a limit to how much I can post on this sub, but I appreciate this sub so much!
I have created a simple tectonic solver and was testing it on a tectonic found here on Reddit. My solver got a bit further than the poster/commenters, but now it's stuck. I am trying to find a new algorithm to implement to solve it, but I cannot find anything.
I'm guessing that A3 can only be 1 or 5, because C3 sees the other cells in the pink block to its left, but even if I put 1,5 as only available numbers on A3, the solver (or I for that matter) is still stuck...
all tips and avenues welcome (i’m begging)! I need to increase brain power for world domination tq

That's my best guess, what do yall think?
I have been trying different solutions for this puzzle for 30 minutes, always coming to a dead end. Strategies for how to go about these puzzles?
The video gives a scenario where you are abducted by aliens along with nine other people. The aliens want to eat you but they are not allowed to eat highly logical beings. They come up with a test to see if they can or not. They tell you the puzzle: They will line you up tallest to shortest, tallest in back facing shortest, each with a hat either black or white. You cannot move out of line or turn around or remove your hat. You have to guess which color hat you have on and at least nine out of ten people have to be correct to win. They can only say either black or white and nothing else. They give everyone five minutes to discuss a strategy before the test begins. They then explain the only guaranteed answer.
! Why can't each person just say the color of the hat in front of them still letting nine people be correct out of ten? !<

Solved: >!This was just a misunderstanding of initial rules of the puzzle, after I rewatched the video I understood my strategy wouldn't work as you can only say guess once and not a second time( like after saying black or white, being able to then know at the end what your color was, the reasoning was because I wrote each color what they would say, and then I figured everyone except the first guy would know the color, so I thoughtt just by them knowing the color, the strategy was valid. I forgot that what they say counts as their guess lol.!<
I’m not sure this is usable! 😂
I have just found out about Star Battle and been very addicted, but I feel I have yet to unlock some form of understanding as I keep getting stuck on these hard ones. without overly spoiling the puzzle, what would be the next logical move? or any extra tips that I have yet to understand? any help would be appreciated! TYIA
Solve the puzzle. You have 20, 50meter long electrical wires bundled in a pipe without knowing which is which. How can you tell which is the other end of each wires if you can only go back and forth 4 times? Using 1 multitester only.
I am an avid puzzle solver and love logic puzzles in particular. The ones that involve process of elimination are just enough of a challenge to make my head spin a little, but I can usually solve it after a few attempts. However, this one featured in a Puzzler magazine from last year has baffled me to the point where I feel there is a misprint / error - but I just can’t let it go. I’ve made three logic grids to try and solve it and eventually looked at the answer and I still don’t think the answer works, due to the options I think you would still have left.
Please help, I’m 36 and really need a life.
Thank you in advance, geniuses of Reddit.
Rules Each binary puzzle has to be solved according to the following rules:
Each box should contain either a zero or a one.
More than two equal numbers immediately next to or below each are not allowed.
Each row and each column should contain an equal number of zeros and ones.
Each row is unique and each column is unique. Thus, any row cannot be exactly equal to another row, and any column cannot be exactly equal to another column.
Each binary puzzle has a unique solution. It is always possible to make a next step by reasoning. In other words, the solution can always be found without guessing.
It's definately not the connection one they're talking about. This is the assorted puzzles section in a mainly crosswords book. I took a peek at the solutions at the back (without looking directly at it), and it's the solution to the puzzle at the top. It seems they messed up the "description" lol
I have designed a puzzle and am very curious to know how it is rated in terms of level and level of fun it provides. I would like to know how this puzzle is rated on a scale of 1 to 10 in terms of difficulty and on a scale of 1 to 10 in terms of enjoyment.
Explanation of the puzzle: The challenge is to cross off the dice used for scoring in your Yahtzee throws into the ‘word search’. It is important to note that throws may only be marked horizontally and vertically; diagonal markings are not allowed. For example, a small straight consists of four dice, while a ‘three of a kind’ consists of five dice, as five dice are counted towards your score. Finally, the aim is to discover how many points have been rolled at ‘Chance’.
Each die can only be used once.

What is the logic to eliminate those squares? At best there are 4 colors within those 5 columns
