Absurdly Difficult Puzzle

(Published on 1. April 2025, 01:02 by juggler)

Today seems like a good day to publish this incredibly difficult puzzle. I'm not even sure if it's solvable by humans, so... attempt it at your own risk.

KROPKI - Cells that are adjacent are separated by a white dot. All possible dots have been given.

COUNTING CIRCLES - The number of times digits appear in a circle is equal to the number of circles in the puzzle.

KILLER - Digits in a cage can't repeat, and sum to the number in its center.

ENTROPIC LINES - Digits on a peach line have low (123), medium (456), or high (789) entropy.

GERMAN WHISPERS - Adjacent digits on a green line may differ by up to five or more.

RENBAN - Digits on a pink line are in a set of orthogonally connected cells in any order.

BALANCED DOMINOS - Orthogonally adjacent cells always contain digits in a 1:1 ratio.

Solution code: Row 7, from left to right

Really glad I gave this one a try.

Fiendish! Rogueish, even!

I got stuck on the instructions for entering the solution. I read it wrong and I kept entering the digits right to left.

My german knowledge, computer prowess, and 3d visualization were vital in solving this challenging puzzle

April showers bring brain powers. Get ready, this one is a DOOZY.

The rules omit this, but not all possible German whispers are given. Or all possible Azerbaijani whispers, either. And yet it's solvable somehow!

This is so stupid. I love it!

VERY NICE wording

I think this puzzle could have been broken through better with some region sum lines or anti-diagonal constraint.

I did it! I did it! My first 5 star puzzle!

Very beautiful puzzle. Has really interesting logic all throughout. First 5 star I’ve solved and definely s 5 stars for me. A tip for solving, make sure to read the rules.

Thankfully Google Translate exists, I don't know if I would have gotten through the German Knowledge requirement without it.

Best puzzle ever!

What a brilliant construction. My first 5-star solution and it was quite the struggle, but the finish was as smooth as I have ever seen. Spectacular.

I may be wrong but it seems that the killer cage on the right is not needed. What is strange is *time out*

My first thought was 'how is it possible 130 people solved a 5 star puzzle in 12 hours', but after 2 hours of solving I finally see the point!

Wow, this was such a difficult puzzle! This had some of the best logic I've seen. Happy to finally complete another 5★ puzzle!

I guess that's one of the puzzles Simon won't be able to solve. As we all know he cannot see given digits.

I'm not gonna say, that I solved that one on paper.

I think the difficulty rating is too high. Max 3 for me

Best ruleset that will ever be!

on 1. April 2025, 09:48 by Asi_Pasasi
Didn't finish reading the rules and got it wrong the first time... The solution was not "Row 7, from left to right"

Absolutely beautiful break-in. I struggled for quite a long time on the longest entropy line, but when I eventually spotted the trick it was so satisfying. Excellent construction as always

Hehe refreshing as always.

on 1. April 2025, 08:25 by Omega_3301
my first 5 star!
such a difficult puzzle, took me hours to get the break-in and it was hard up until the very last cell. thanks juggler :)

Not just difficult. Literally and provably impossible!

on 1. April 2025, 06:24 by Voidslime
I had to cheat just to get started. Given that SKORP17 hasn’t even beaten this I’m willing to bet we all cheated to get through.

So much fun logic

Ahahahaaa..niiice)))

This puzzle is sick. Filthy. Absolutely outrageous. It shouldn't exist in nature. Yet, here we are. And it gave me pure joy and a hearty laugh when I cracked it.

on 1. April 2025, 02:34 by atpx8
Took me a good few hours, truly beautiful logic though.

on 1. April 2025, 02:15 by DasBooch
Can confirm this is theoretically solvable by a computer.

Absurd Puzzle
(but might be a sign of the times)

Simply stunning logic. I wasn't sure I was going to be able to complete it but it just came together so neatly at the end.

on 1. April 2025, 01:08 by sujoyku
Wow, that was a tough one. But solving experience prevailed and I finally got the brutal concept for this break-in. Thank you, Juggler!
