- Normal sudoku rules apply, i.e. each row, column, and 3x3 region has to contain the digits from 1 to 9 once each.
- Top Right Boi: The digits in the top right position of all 3x3 boxes form an index line. In other words: If the top right cell in Box A contains the digit B, the top right cell in Box B must contain the digit A. (Box numbers are read from left to right and top to bottom.)
- Dutch Whispers: Adjacent digits on an orange (solid) line must have a difference of at least 4.
- Renban: Each pink line (with little white stripes) must contain a set of consecutive non-repeating digits in any order.
- Kropki: Digits joined by a black dot have a 1:2 ratio. Digits joined by a white dot are consecutive. (Not all dots are given.)
- X: Digits joined by an X must sum to 10. (Not all X are given.)

Den boi-Witz habe ich zwar nicht verstanden (irgendeine „oben rechts“-Regel musste wohl vorkommen), doch das Rätsel ist wieder einmal erstklassig. Vielen Dank dafür.

I really enjoyed this. The little aesthetic touches go a long way, too, this is a beautiful grid.

Thank you for your comment, ViKingPrime! I am glad that you enjoyed the puzzle. Initially, I made the changes mainly for the purpose of being more colour-blindness-friednly. But I also liked the new look of this boi.
Kind regards, sujoyku
