The New Sudoku Players' Forum

[Hajime]

My first Gattai-Wing with 3 Sudoku's (symmetric)
- a GT (Greater Than, where is no < or > the relation is unknown)
- a XV (X sum up to 10, V sum up to 5, where is no X or V the sum is not 10 or 5)
- a KR (Kropki, Solid dot = double or half the other, Open dot = consecutive, where is no dot: not consecutive and not double/half)

Naked/Hidden Singles only, but some GT,XV,KR rule eliminations needed

Edit: correct picture is later in this topic

Two extra lines needed per Sudoku, first line with 81 symbols per cell-to-the-right and the second line for cell-below.
The zeroes indicate: there is no adjacent cell to the right or below.
The last Sudoku has a 1 for consecutive cells and a 2 for cell double/half from the other.

Will this be part of a next version?

Sure, the methods are implemented. Busy with batch-out generating puzzles with GT,XV,KR option.
Greatest problem sofar was the visual basic DataGridView (grid layout) that can not handle symbols on borders (and are pretty slow).
I had to reprogram this (the heart of ssss) into invalidate/paint of bitmaps. Huge change internally, hardly visible for the user.

Yes, only the drawing for ^ is displayed as V, paste-able format is correct.
It has a single solution:

the XV has exactly one answer:

b1 4 not in r1 next to 1,
