Calcudoku+ 7×7
I had a request for a 7×7 Calcudoku-esque puzzle that uses only + operations, so I thought “why not?”. And here it is.

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 >

Calcudoku 6×6 puzzle
It’s been an age since I’ve posted new puzzles on here directly, mainly because all my puzzle-making effort has been focused on Sudoku Xtra, Sudoku Pro, PuzzleMix and a major book I recently completed.
In any case, there’s no time like the present to fix that so here’s a simple 6×6 Calcudoku. Just place 1 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 >

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 >

Samurai-2 Odd Pair Sudoku puzzle
One of the brand new puzzles in Sudoku Xtra issue 4 is Odd-Pair Sudoku, which I wrote about last week here on my puzzle blog. As well as some regular 9×9 puzzles I also included a large 5-grid Odd-Pair Samurai puzzle, and to illustrate how the puzzle worked I included a More >

Samurai Killer Calcudoku puzzle
I haven’t posted much here recently because I’ve been spending my time on Sudoku Xtra, so here’s a large puzzle to fill the void a bit.
This is a five-grid Samurai Killer Calcudoku:
Place 1 to 9 into each row, column and 3×3 box of the five underlying 9×9 Sudoku grids
Place numbers into the Calcudoku dashed-line More >

Inequality Calcudoku puzzle
Here’s a fun little puzzle – a Calcudoku Inequality puzzle.
Just place 1 to 6 into each row and column whilst obeying the bold-lined cages’ operator totals. These give the result of applying the stated operator between all numbers in that region, so for example the result of adding together all the squares in More >

Well that was a bit of a marathon but I’ve finally completed it. When I first started it and saw the large number of givens I mistakenly thought it might be easy!! In the event it’s taken me quite some time, but hugely enjoyable

I saved that puzzle for dessert!
That was muy mucho fun! It took some time but considering that you are doing 8 9×9 CalcuDokus (sans 3×3 regions) it was a fun wrestle.
My suggestion would be to make it clearer where each row/column ends. There were a couple of times I almost flubbed it thinking an overlapping region couldn’t have a number but checking again I saw that it was 1 square out of range.

I agree. This is something I used to do (mark the row/column boundaries), but when I re-wrote my PDF creation code for a new library I didn’t put that back in – however I should. It is particularly confusing if you switch from Samurai Star to ‘regular’ Samurai puzzles!
