Greetings! Thanks for all of the work that you put into keeping this site going. It's a real treasure.

Question for you: The rules for consecutive sudoku are:

"Place a digit from 1 to 9 into each of the empty squares so that each digit appears exactly once in each of the rows, columns, 3x3 box. All two adjacent cells that have a small circle between them are consecutive in value. "

My question is this: Are all adjacent, consecutive cells marked (which implies that any non-marked cells are not consecutive), or is the given that only some of the consecutive cells are marked? I think that yesterday's "Easy Variant" relied on the interpretation of this rule where all consecutive cells are marked, so a 9 could not be next to an 8 unless there was a small circle indicated. The scores and ranking don't really bother me, but if it's true that all such consecutive cells are marked, then it seems that the wording should be revised.

Thanks,

Jeff

Consecutive

Thanks Kodyn. I asked the question because I didn't really know whether or not "If a small circle is not given, the two digits cannot be consecutive" was true. I appreciate your clarification here, and with the wording.

Consecutive

Hi Jeff!

Thank you for your compliment. I appreciate it very much

About rules of Consecutive Sudoku.

Those rules are used very often and as you've said the main part is on the word "All".

But I can change them into this formulation:

Place a digit from 1 to 9 into each of the empty squares so that each digit appears exactly once in each of the rows, columns, 3x3 box. Additionally, if a small circle is given between two adjacent cells, then the two numbers in those cells must be consecutive. If a small circle is not given, the two digits cannot be consecutive.
