The gattai variants are included in a zip file attached below - for each variant there is one each of Easy, Medium and Hard puzzle.
The puzzles' difficulty levels are as follows:
Easy - requires only naked and hidden singles to solve.
Medium - cannot be solved by 'Easy' methods, requires locked candidates, naked and hidden pairs to complete.
Hard - cannot be solved by 'Medium' methods, requires other advanced methods (currently naked and hidden triples and quads, and the basic fishes) to finish solving.
I named the 4x3 boag, and will discard it if a name for it already exists; I prefer this on 2 printed sheets, but the harakiris and fat samurai on a single page are also likable.
The 4-nonet overlaps (Sensei-4 and TripleDoku-4) cannot be created by this gattai-maker! - either more solving methods in the solver will help, or making them will require an amount of human intervention!
All the puzzles created have no givens in the connecting boxes (nonets). The Kazaguruma is an exception, it could only be created if I relax this rule, so I've allowed this. I think the Sensei-4 and TripleDoku-4 can also be created if this rule is relaxed, but I have not tried. Many of the puzzles I see on the Internet have givens in the nonets!
The attached files are in same formats as before - they contain gattai-maker outputs in sudoku lines, spreadsheet paste and raw compact formats, followed by the gattai solution in the same formats. The filenames are in the form: [gattai-type]-[datetime-generated].[level] with a '.sud' file extension.
