How is the pairing done ? What is the logic ?

As per the score page, many players paired Nine Dragons + Skyscraper first. So I will share the logic to do that pairing.

Note that In ND (Nine Dragons) you can put a 7 at R6C6, which rules out it being paired with Nonconsecutive Or AntiKnight.
ND can't be paired with Irregular (8 given in box 4)
ND can't be paired with Disjoint (5 given in row 4)
ND can't be Odd Sudoku (8 given in column 3)
ND can't be Sum Sudoku (Try to satisfy row 6 of Sum Sudoku, given that R6C6=7)

So ND will have to paired with Skyscraper.

----
There are many other ways to get the pairing done too.
You can check the attachment where you will notice that you can put few digits in each of ND, Irregular, Disjoint.
It will be obvious that these 3 can't be paired with each other, and they also can't be paired with AntiKnight or with Non Consecutive. So AntiKnight goes with Non Consecutive.
Irregular can't go with Odd Sudoku (Check 8 at R1C3). And Irregular can't be Skyscraper, which you would have deduced from the beginning itself (because of 8 at R4C2). So Irregular goes with Sum Sudoku.
Now Disjoint can't be Skyscraper (8 at R2C7) and it can't be Sum Sudoku (9 at R1C2), So Disjoint has to be Odd Sudoku.
