Somethin' Stupid
(Published on 22. September 2025, 18:18 by sujoyku)
Rules:
- Normal sudoku rules apply, i.e. each row, column, and 3x3 region has to contain the digits from 1 to 9 once each.
- Renban: The pink line (Ren) must contain a set of consecutive non-repeating digits in any order.
- German Whisper: Adjacent digits on the green line (GW) must have a difference of at least 5.
- Region Sum Line: Box borders divide the blue line (RSL) into segments with the same sum.
- Palindrome: The digits on the grey line (Pal) form a palindrome, i.e. they read the same forward and backward.
- Index Line: The turquoise line (Ind) is an Index Line, i.e. the digit in the Nth cell along the line (starting from the diamond) indicates the position along the line where the digit N appears.
- Arrow: Digits on the arrow sum to the digit in the circle from which the arrow emerges.
- Double Arrow: The digits on the line between two circles must sum to the same total as the digits in the two circles.
- Killer cage: Digits in the cage must sum to 7.
- Odd: A cell with a grey circle must contain an odd digit.
Here you can solve the puzzle online:
Solution code: Row 7 from left to right (9 digits in total)

I just started getting in to sudoku variants and having such a beginner friendly puzzle with so many different rules at the same time was a lot of fun! Thank you for the great time it provided.

Kinda silly, but it's fun to solve a complex-looking puzzle that's really just a string of smooth, quick eliminations.

Stupid - war hier nur ein fehlerhafter Eintrag meinerseits, durch den Ich die Lösung erst einmal ruiniert habe! (War mal wieder zu hastig unterwegs.) Vielen Dank für das hübsche Puzzle.

Easy but still a little bit of deduction behind each step. Thanks!

Another fun one! I would think this is a higher 1*, simply because the cage in box 7 makes the GW in box 4 trivial and it really flows from there, but I could see where it could be a 2* as well. Will be interesting to see where it lands. Irrespective of the rating, was a really fun solve. Thanks for sharing so much with this community. Really appreciated.

You are much welcome, PinkNickels, thank you for your comment! I am glad you had a fun solve. Concerning difficulty: I was torn between 1 and 2 stars and decided to err on the hard side. So either way it turns out, I will be fine with it.

You practice everyday to find some clever lines to place to make your puzzles feel smooth.
