I'm not sure what the last part means. Every Next to 6/9 Sudoku will have, outside each edge, a set of 7 double digit clues and 2 single digit clues, and the rows/columns with single digit clues will be the ones where 6/9 is in the 1st or last cell (this is easily explained - because everywhere else, 9 will have one cell before it and one cell after it)

Sorry for the late reply. Thanks Prasanna for your valuable input. Just wanted to clear whether every Next to 6/9 Sudoku will have only one outside clue.

The above is only true if ALL clues are given. There can still be Next to 6/9 sudokus with not all clues given, or more than two single digit clues given.

I just meant whether every Next to 6 /9 Sudoku will have single digit outside clues. Sorry for the miscommunication.
Also one more request : Can the instruction booklets for the rounds be published a bit earlier, coz for beginners like me it takes time to understand the variants. Thanks

I would argue that it's implied that if there's a clue at all in a given row or column, it will list all neighbours of 9 within that row or column. Otherwise, the rules would better be phrased along the lines of: "Clues outside the grid indicate numbers that must placed before or after the 9 within that row or column."
I'm sure someone will explore these variants soon!
