Samurai Sudoku 9×9 / 6×6 cross-over

I’ve decided it’s time to start posting puzzles online again, after a hiatus of about a year over on my old blog site.

I’m moving from my own bespoke blogging system to a standard one (WordPress), although it’s taken me a lot of effort to get PDF thumbnailing working!  There doesn’t seem to be standard support for this, so I had to write my own PDF to thumbnail plug-in, which took a good few hours given that I knew nothing about WordPress – but anyway it now finally does work, so I can post my puzzles (like the attached) and get a decent thumbnail on the page too.

If that doesn’t make much sense, the basic point is that the small preview pictures like on the right will appear when I post puzzles automatically without me having to make each one by hand from the original PDF file.  It also means when you click on them you’ll get a top-quality PDF ready for printing out at whatever size you like, rather than a fuzzy JPEG.

This puzzle is a 9×9 / 6×6 overlapping Samurai.  The idea is to place 1 to 9 into each of the rows, columns and 3×3 boxes of the larger (top-left) grid, whilst placing 1 to 6 into each of the rows, columns and 2×3 boxes of the smaller (bottom-right) grid.  Where they overlap there is a 3×3 box and a 2×3 box.

Good luck!  It doesn’t need any tricky logic so shouldn’t be too taxing.  Please do post a comment here if you like it, don’t like it, or indeed have anything to say at all!
