The numbers in columns 1, 3, 7, and 9 and rows 2, 4, 6, and 8 are all 4 groups 1-9. The yellow numbers 1 and 3 are offset. The purple is the common cell where the rows and columns meet, and the corresponding column is red. The {1289} will be filled in the red cell of the corresponding row, and the same is true: the blue {4567} of the corresponding row will be filled in the blue cell of the corresponding column. As shown in the picture, this is an important spoiler, without it, it may be difficult to move an inch! After this, an X-Wing of 5, an Xy-Wing of {469}, and a unique rectangle of {28} may be applied. This is a five-star puzzle!
Lösungscode: Zeile 7, gefolgt von Coloum 2.

Almost all solvers solved it when there were no hints at all. I agree that this is a general problem of the rating system, but it's a hard one to fix.
This is the equivalent of a very hard chess study you only understand after it is explained by a GM.
It breaks with the right guess, but before, even Andrew Stuarts solver throws the towel and can't calculate a difficulty rating because it can't find a path.

I have to say that I am very much disappointed by the low rating on this sudoku. The key idea is a very beautiful one!

Absolutely fascinating - this puzzle breaks scanraid. I'm not sure I've fully understood what is going on, but it's clear this puzzle is a gateway into previously poorly understood structures woven into the fabric of Sudoku. Thanks for sharing!
