Just place 1-6 into each row, column and bold-lined area.

Sudoku 16×16 puzzle
And to complement the Killer Sudoku I posted a moment ago, here’s a 16×16 puzzle for those who like these. Just place 1 to 9 and A to G in each row, column and 4×4 box. Only “scan and place” logic is needed for this, I promise!

Samurai 8X puzzle
When I was making Sudoku Xtra 10 I wanted to put in a really big Samurai Sudoku puzzle. In the end because I had a square page area available beneath the instructions I went with a 13-grid one (just as a one-off to see what sort of reaction it got!) but I had More >

Killer Plus Minus Samurai puzzle
If you’re a Sudoku Xtra reader you’ll have seen these in their regular 9×9 form in both issues 5 and 6, but this is the first time I’ve made a Samurai one, and the first time I’ve posted one here I think.
This is essentially a regular Killer Sudoku puzzle, except that More >

Killer Sudoku Pro 6×6 Samurai puzzle
It’s been quiet here recently – much of my effort has been going on my UK General Election site, How To Vote, although Sudoku Xtra 6 was out on Saturday too. Anyway, there are still 10 days to go to the election but after that I’ll get some time back!
However I thought I should More >

Samurai 3-grid Calcudoku 6×6 puzzle
I’ve been posting a few new varieties of Sudoku puzzle in the daily puzzle section of PuzzleMix (i.e. the subscription section, which costs less than £1 a month for well over 1,000 puzzles a year). These aren’t especially unusual variations, but I’ve done a few different mixes (e.g. Sudoku-X 12×12 and More >

Toroidal Killer Jigsaw Toroidal puzzle
A while back someone asked for some variant toroidal patterns on PuzzleMix, so I was just adding a couple of them to the daily puzzles section when it occurred to me that I could put up a few toroidal killer sudoku too, for a change. However I then realised that the More >

Samurai Star XXXXX puzzle
I haven’t posted a puzzle for a week (it’s been a busy week, mind!) so it’s time to make up for that, just in time for the weekend.
In this puzzle the aim is pretty simple: place 1 to 9 in each set of 9 squares starting and ending with a bold line, More >

I wrote quite a lot yesterday about whether you “needed” the X in some Sudoku-X puzzles. I promised that I’d follow up with the result of analysing a stack of Killer Sudoku-X puzzles, and so here is that result.
I picked 64 Killer Sudoku-X puzzles (52 for the daily puzzlemix section plus 12 for the weekly More >

This puzzle is driving me mad!!! I’ve printed it out 3 times now, and managed to go wrong each time in both the top left and top right hand grids. I really don’t feel ready to give in yet (I hate a puzzle to get the better of me) but I wondered if it would be possible to send me another couple of numbers to try and help me on the way a bit, or if that’s not possible without giving too much away?

Sorry you’re finding it tricky!
The top-left row of the puzzle reads as follows: 547918362.
Does that help?!

Perhaps I am getting better at these, because I enjoyed this puzzle over the samurai star one. It also may have been that I gave myself enough time to do it rather than be interrupted by other things. Looking for the conga-line chains helped.
One thing I noticed: I finished the upper right sudoku first and found that even though a part of it was jigsaw that the whole sudoku followed the 3X3 region rule as well. I assumed this was because of the many 3X3 regions in the whole puzzle … and shifting between jigsaw and 3X3 for the edges helped me solve the puzzle quicker.

Thanks for those numbers Gareth – just off to have yet another try now! I’ll let you know how I get on.
Well done Spittledung – and I have noted your comments on the jigsaw/3 x 3 areas because I was geting a bit confused there. That has clarified matters for me because I had got a couple of wrong numbers in there.
