This puzzle has simple and familiar rules.
So it is a Sudoku Jigsaw, kind of ...
So it is also a Killer, kind of … and a Kakuro, kind of ... It's printer-friendly, in any case. And this one should be quite easy. Some instant fill-ins should be quickly identified (think "rule of 45"). Puzzle image: Solution: |

A customer at last! Thanks! I see great potential for this kind of puzzle, but was beginning to wonder why nobody else did ... Would you care to see a more challenging example? |

I'd love to see it! I may not solve it, but I'll give it a shot! |

Very clever idea! I've always liked Kakuro. As you say - not too hard. I too would like to see the harder one! |

. Ok, the software is a bit raggedy at the moment, just a proof of concept prototype, but I can and will use it to give you a harder puzzle. This should be available within 12 hours of this post! Thank you both for your interest! |

I finally got the grid template manager and the solver/generator to communicate, so we can change the layout. This puzzle should be anything but routine: Puzzle image:: Solution:: |

Oh dear, I seem to have lost my audience ... Did I make the puzzles too hard? Not hard enough? Not interesting enough? I have no time at the moment for P&P trials myself, so feedback would be really useful for me … |

As I commented to Mathimagics, when I first saw these puzzles I wasn't sure how I would set them up in Excel worksheets, which is how I solve puzzles. I've now settled on this format (see below), for each cell the first number is the horizontal cage total, the second the vertical cage total and the third, of course, if for candidates; there may well be a better way for those more expert with the options available in Excel. The demo version is, as one would expect, an easy one so I won't post a walkthrough. Simple Hints: These puzzles are very similar to Texas Jigsaw Killers. Next time I update the TJK Archive, I'll add these as a separate table.
