## Foldover XV

(Eingestellt am 11. Januar 2021, 16:41 Uhr von GremlinSA)

Normal Suduko rules apply. All adjacent cells with two digits summing to 5 are marked by V, while those summing to 10 are marked by X. The cells edges which do not contain an X or a V cannot have digits summing to 5 or 10.

if the puzzle is folded along the diagonal given, the overlapped cells sum to 10, EXCEPT for any of the digits that appear on the diagonal which will simply transpose. In the two cages given the digits must sum to the total given in the top left corner.

HINTS + TIPS

'5' conforms to both rules, it will transpose and sum to 10 when folded over
All box's will have 3 cells that transpose, the rest sum to 10 when overlapped
The diagonal will will have 3 sets of the same 3 digits

Lösungscode: Row 2 , Col 8

@Gremlin: So are you saying that we essentially have the same rules as this puzzle (id=00048T), but where a number is either a "buddy" with itself or 10 minus itself?

Edit: Just read Narayana's comment, and it seems to be the case.

I think you should simply clarify the wording of the instructions and not give away the puzzle with the hints part. It is good form to put any spoilers hidden either in black or white so that only by highlighting the person can see it and not by mistake. You can edit the Html to accomplish this see for example the code for

I would have enjoyed the puzzle a lot more if that rule was less ambiguous and if I had been given the chance to deduce the self transpose digits myself. Since only one was obvious and the other 2 are now revealed all over the place in the comments and the puzzle.

I don’t think I am alone in understanding the rule “EXCEPT for any of the digits that appear on the diagonal which will simply transpose.”

As “the rule applies to every cell on the puzzle except for the cells in green” When what you actually meant was if a number appears in a green cell then that number <b>throughout the puzzle </b> won’t satisfy the rule above, furthermore if N is such a number and appears in Row R and Column C then N also appears in Row C and Column R.

An alternative way of stating the rules: Every digit A in the grid has a transpose pair A*, i.e. If digit A appears in Row R, Column C then the transpose pair of A appears in Row C, Column R. Transpose pairs must satisfy the following property. Either A+A*=10 or A+A*=2A.

HINTS and Explanations

In the Rule set it does specifically say that any digits that appear on the fold will transpose when overlapped. I.E. Each box has 3 cells that transpose (the same 3 digits in each box)

So yes all the 4's and 6's reflect onto themselves, and not to each other. the digit 5 is the only one that abides to both transpose and sum to 10.

Some 4's and 6's end up being reflected onto themselves rather than each other.
