I like the mix, it’s a unique challenge, which is cool. Only downside is that the solvers don’t support it. My typical solvers are jSudoku, SudoCue, & sudokuwiki.com, although I can’t find a working download link for SudoCue anymore so I don’t have it on my new machine, a shame since it’s the only one that does the alternate RN & CN boards.

Frame Sudoku is basically double-killer without innies & outies, still undecided if I like them or not

this is a really nice sudoku on its own. As long as I could get out of the jigsaw, the frame sudoku didn’t seem that unsolvable. Realy nice how it develops while solving it.

More of it! ðŸ™‚

ok, well having solved the jigsaw one fully, and the central one partially and the outside sudoku partially, I’m totally stuck… the killer jigsaw doesn’t seem solvable on it’s own and the frame sudoku, although I’ve solved >50% is not helping break into the central puzzle that much. Is there some particular trick in this one that is hard to spot? I’ve filled the remainder of the outside sudoku with candidates but it hasn’t helped….

In the book Loco Sudoku, what is the purpose and/or strategy of puzzle 15 on page 14?
