Diagonal consecutives
Inspiration for this type comes from Md88keys.
Solve online in Sudokupad.
Apply classic sudoku rules.
Some intersections of gridlines are marked with a circle or a small dot. A dot indicates that exactly one pair of diagonal opposite cells contain consecutive digits. A circle indicates that both pairs of diagonal opposite cells contain consecutive digits. The digits placed in such a circle have to appear once in the four cells that the circle touches. All possible dots and circles are given.
Solution code: Column 6

Reply: that is very well possible. That's why I didn't put in the digits, but replaced them with question marks. Since all dots and circles are given, I had to place a circle there too. :)
