Hidden Patterns
(Eingestellt am 25. Januar 2025, 03:13 Uhr von PhoenixAki)
This is my first puzzle that I intentionally designed to be approachable and I quite like how it came out. The way I designed it was I started with placing the patterns into the grid and then applied rules until it was unique and fun. Good luck!
- Normal sudoku rules apply. Place the digits 1-9 in each row, column, and 3x3 box without repetition.
- XV: Digits separated by an X sum to 10. Digits separated by a V sum to 5. All X's and V's are given.
- Dutch Whispers: Adjacent digits on an orange line must have a difference of at least 4.
- Consecutive Pairs: Digits separated by a white dot must be consecutive.
To increase accessibility to my puzzles, I include hints in my puzzle posts (see below). I also post solution videos on my Patreon and YouTube channel. Puzzles released prior to February 2026, as well as my snackdoku and variant sudoku 101 series will continue to get public solution videos on YouTube, while others will be Patreon-exclusive.
Hint 1: The V clue in R1C1 and the V clue in R4C3 force the pattern of lows and highs on the Dutch whisper line in box 1. How must the Dutch whisper be filled now?
Hint 2: Once you pencilmark the X's and V's after resolving the whisper line, there should be a sneaky pair of digits in column 2 that resolves most of the rest of the clues in column 2.
Hint 3: Don't forget the negative constraint! There's a lot of spots you can use it at, so always be looking for cases where 2 digits could add up to 5 or 10 without a V or X there.
Lösungscode: Row 7, from left to right (9 digits)

Added hints after learning recently how to do that in HTML. Wish I knew this last week when I went over all my posts...oh well.

Updated post as part of an effort to improve consistency of rule phrasing and post layout across all my puzzles. Similar edits will come to my other puzzles soon™

I thought I found the patterns first, but wanted to challenge myself to do it logically. Nice one!

Oh man. I was so stuck at the end. Then I read the rules and missed that all the Vs and Xs were given!
D'oh. :D

Despite the bold lettering about the negative constraint on Xs and Vs, it didn’t sink in until I could not resolve the last 10%. Then I reread the rules and had a fun finish.
Nice puzzle.

A nice little 5-minute puzzle. Took me a bit to see the patterns after finishing, though.

I don't know why, but I offen struggle with XV puzzles. But even I managed this one and it was fun.

I needed this true one-star puzzle because I was struggling with a different one-star puzzle. There’s quite a range! Thank you.

i wouldn't worry about it being too easy. took me 40+ minutes. and every time i thought i had the final break to make it all collapse i had to go looking for another one. good puzzle. but then any puzzle i finish is a good one. :)
