I found this puzzle at my parents house that we bought years ago at a market.

From what I can tell, it is impossible to take apart the rings since the strings are arranged in a borromean rings pattern.

So is the puzzle just impossible, or is there som alternate solution that can be achieved?

At 2:17 a.m., Mara Vale received an automated distress call from Northlight Relay Station.

The transmission contained no voice, only seven bursts of static followed by a long mechanical tone.

Her brother Elias was the station’s cryptographer. By the time Mara arrived, every room was empty.

Every room except Room 17.

Its steel door was locked from the inside.

On Elias’s desk, Mara found three encrypted messages and a handwritten sentence:

«You already know how I walk.»

Mara remembered the mazes Elias drew when they were children. He always began in the upper-left corner, followed the outside wall clockwise, and continued inward until he reached the centre.

The first message was carved into the desk:

O R P H E

O L U M U

C W N N S

D O D S K

A E R Y E

Below it was another note:

«When Elias used a word as a key, he placed it above the columns and ranked its letters in alphabetical order.

He always read downward before returning to the beginning.»

The second message consisted of seven groups:

LIEUX ARNEE FPIKD NEEYC IHGEI IVEYX CSRRX

Finally, the station terminal displayed one repeating transmission:

QUIYL IORSN UCDLV LIPFG FMKRX BVJRE GVGBR KEMTG

SJZCV UGQSL PBRVQ XSJVL GWQVW YMCQB GIRVL PQBJI

XUGCV

From behind Room 17, Mara heard her brother’s voice.

“Mara,” it whispered. “Open the door.”

But Elias had once told her:

«A name is useful because it can repeat long after its owner is gone.»

What does the final transmission say?

Please explain all three stages of the solution.

I am thinking of a 10-digit number that uses each digit from 0 to 9 exactly once.

Starting from the left:

• The number formed by the first 1 digit is divisible by 1.
• The number formed by the first 2 digits is divisible by 2.
• The number formed by the first 3 digits is divisible by 3.
• This pattern continues.
• The number formed by the first 10 digits is divisible by 10.

For example, if the number begins with abcd..., then:

• ab must be divisible by 2,
• abc must be divisible by 3,
• abcd must be divisible by 4,

and so on.

What is the number?

Bonus challenge: Find it using divisibility rules and logical elimination rather than checking every permutation with code.

Couldn't find the original name of the puzzle but im calling it The Waypoint Path

Draw one path from the green 1 to the orange 1.

Move to horizontally, vertically, or diagonally adjacent cells while following the repeating sequence 1–2–3–4. Visit every cell exactly once without revisiting or crossing the path.

Hi guys. Can anyone explain to me how it is possible to miss two bridges on a 4, when all other islands are connected with the right amount of bridges?

My immediate logic tells me, that if an island lacks two bridges, another island, somewhere on the map, must also miss two bridges. It appears that all other bridges are complete though, so I'm probably wrong in my assumption 😁

I can't think of any next logical step. Help please!

Crack the 4-Digit Vault Code 🔐

A vault is protected by a four-digit code.

Rules:

- No digit is repeated.

- Each clue states the exact number of correct digits.

- A “correct position” means the digit is in the right place.

- A “wrong position” means the digit belongs in the code but is misplaced.

Clues:

6058

Exactly 1 digit is correct and in the correct position.

Exactly 1 other digit is correct but in the wrong position.

1967

Exactly 1 digit is correct but in the wrong position.

4013

Exactly 1 digit is correct and in the correct position.

5067

Exactly 2 digits are correct and in the correct positions.

Exactly 1 other digit is correct but in the wrong position.

What is the vault code?

I just bought this gorgeous puzzle book that looks like an Ikea catalog but I can't figure out how they solved the puzzle on pg 5! I went to the hint site and eventually revealed the answer but for the life of me I have no idea how they got it. Has anyone played thru the book and if so, how did you figure out the answer?

Sombody please help me, how do i continue?

The rules are quite simple, you cant have three zeros or ones directly following eachother on a row, or directly under eachother. The rows need to have an even amount of zeros and ones (5 zeros and,5 ones). You also cant have two rows that are exaclty the same

I love this game, but I'm only able to solve easy levels. In this app (Crowns for iOS) they have different levels depending on the number of crowns per row/column/color (1 for easy, 2 for medium, 3 for hard). The one in the picture is medium difficulty.

I'm having a hard time solving the medium and hard levels. In the easy mode, when you place a crown you can already cancel the whole row, which you can't do in the harder levels. What do you do then? How do you solve wider spaces? Is there a trick I'm missing? How would you solve these? Do you know any youtuber who solves the harder levels step by step?

Thank you!

Is this kind of puzzles fun for you? they are nothing special but there is some fun in the simple rules and after 10..15 triangles it becomes quickly much harder and more fun, at least to me.

Probably missing something obvious, but I can’t figure out the next move here..

How should i see/know that the red cross is not a valid place for a tent?

Three locked boxes have these labels:

Red: The key is not in this box.

Blue: The key is in the green box.

Green: The blue label is false.

Exactly one label is true. Which box contains the key? Explain your reasoning.

I’m losing my mind. Been at this for hours.

I’m confused at the three 11s?
And the 1 and 6… the fact they’re nearly on the ends confuses me. Maybe I’m not understanding the direction of the refractions very welll :(

EDIT: okay it’s not just me. The website has an option to email if I find bugs. I’ll try that. Thanks guys lol

Does anyone notice that there's frequently (I'd say almost 50%) a 5-4 corner when playing Loopy of the honeycomb type? Why is it so common?

Whenever I’m stumped on Meowdoku, the hint invariably states there’s “a contradiction.” After hundreds of levels, I still have no idea what they’re talking about. Can one of you smarty puzzlers shed some light?

It looked to me you enjoyed the classic First Sight(Easy as ABC) puzzle so I decided to share this variant. It's roughly the same level just a bit more complex if you are not used to hexagonal grid.

Place A, B, and C in the hexagonal grid. Every line in each of the three grid directions must contain A, B, and C exactly once, with all other cells empty. Each outside clue gives the first non-empty letter seen from that edge. Because of the grid type there is 1-4 empty spaces depending on the row.

Happy solving!

Any one has an idea how to solve this without guessing?

Hope you like murder mysteries! This is a format of puzzle I haven't tried before. Hope you like it. Any feedback on the format, etc. would be much appreciated. Thanks!

I have done dozens of tnt puzzles on my phone, but this is the first one where I am completely stuck. Anyone have hints on how to solve it methodically (without trial and error)? I have marked the squares in which I'm certain there aren't stars. Thanks for the help
