Sudoku Xtra website

Just a quick update to my previous post – there is now a preview of issue 1 available on SudokuXtra.com.

Sudoku Xtra Complete

SudokuXtra printed coverSudoku Xtra issue 1 is now ready! It won’t appear on Amazon.com for up to a week or so – it takes a while for them to update their databases and so on, but it is on Lulu.com already if you want a printed version. For the printed version it will cost £4.99 for UK customers, but Lulu do charge postage and packaging on top of that. (Lulu do however often have discount vouchers, so you might manage to get some money off the total).

The magazine is 44 pages long, each page 8 inches by 10 inches (20cm by 25cm), and with exactly 100 puzzles in. It prints really well on both A4 and Letter paper, either 1-up (one page per sheet) or 2-up (two pages per sheet) as you prefer. There is a small preview on the Lulu site if you’d like to see what you’re getting (or read back through previous posts here too!). If you order the printed Lulu version you will actually get some extra blank pages at the back to make it up to their minimum page count for an A4 publication, so ignore the page count on the Lulu description.

I haven’t yet set up the subscriber ordering site (it will be at SudokuXtra.com hopefully within 24 hours), but if you want to get in right away you can click directly on the Paypal buttons below, and then I will email you a PDF version of the magazine within 24 hours. Once the website is up and running you’ll receive the magazine immediately, so this is just temporary for the next day or two.

If you’re in the US or Canada and want a printed copy you have three choices: wait for it to appear on Amazon in a week or more (you might want to do this to get free delivery as part of a larger order), order from Lulu using the link above, or (for the 8″ x 10″ Amazon.com version but without the option of free postage) order a printed copy of Sudoku Xtra from CreateSpace.com instead, who supply the printed copies for Amazon (in fact they’re owned by Amazon too).

However the best option of all for me – the one where I get most money from the sale – is to order a download version and print it yourself. You can print either the whole magazine or just the pages you choose. If you’d like to do this you also have the option to subscribe for a year (12 issues) for the price of 11 issues, if you’re keen! This also insures you against any price rises that might happen in the coming year. Just click one of the four Paypal purchase buttons below.

Note that when buying on Paypal you can click the ‘Continue’ link next to “Don’t have a Paypal account?” to pay directly with a credit card – you don’t need to create a Paypal account if you don’t already have one. The checkout process will say ‘PuzzleMix.com’, which is another of my sites.


Issue 1 @ £3.99 GBP
Issue 1 @ $5.99 USD

Or for a 12-issue subscription:

Issues 1-12 @ £43.89 GBP

Issues 1-12 @ $65.89 USD


Thanks in advance, and I hope you enjoy the magazine! :)

Xtra Progress

I’ve been away for a couple of days but I thought I’d post an update on how Sudoku Xtra was going.

By Friday night I had a complete draft of the magazine, without solutions yet in it, and so I spent the weekend away checking through the proofs and re-solving many of the puzzles.

Today I made a few revisions and so now I can confirm that apart from laying out the solutions (and finishing the colour cover that will go on the Amazon version) it is fully complete.  There are exactly 100 puzzles in the first issue of the magazine, including several full page ones, and I’ve tried to include something for everyone – so there are some large grids for the people who want them, but they don’t dominate the magazine by any means for the people who don’t like them.  I’ve also included some unusual variants which you probably won’t have come across before.

Because probably the majority of readers will be printing their own copies from a download version, I’ve designed it so that each individual page can be printed alone – each sheet is a standalone ‘work sheet’ of a particular type of puzzle, including summary instructions and an example solution.  So you don’t need to waste paper printing the whole thing – you can easily skip the puzzles you are less interested in, or only print them when you’re ready for them.

I’m really very pleased at how it’s turned out, and hopefully you will be too when you see it!  Thanks very much to everyone who has posted here or emailed me directly with comments on what they’d like to see, as well as on Sudoku Pro – you’ve really helped encourage me to get it done quickly, and it’s definitely informed the puzzles I’ve put in.  (For example I was going to not include any super-large regular Sudoku but after a few requests I’ve made sure there’s some in there, including a rather unusual 20×20 Sudoku with 5×4 boxes.)

It will be out this week, certainly by first thing Friday for anyone who would like it in time for the weekend. And that’s a promise! :)

Sudoku Xtra Progress

Sudoku Xtra preview double-page spread

(Yes, that’s not Slitherlink on the right but this is a mock-up at the moment!)

I’ve been working hard on Sudoku Xtra today and hopefully my new magazine will be ready really soon. Of course the first issue of anything will be more work than subsequent issues (I hope!), since there’s so much more stuff to do – from the title to the content to the basic design to all the infrastructure around it. Right now I’m just getting to the point where I’m happy with the page layouts and basic design, thus this posting to preview it.

Any design needs to print fine on black+white printers, but I’ve used a small amount of extra colour throughout for page top/bottoms so it looks a bit nicer when previewed on screen (and a little shinier if you have a colour printer), and I can vary this colour from issue to issue.

It’s an interesting task to design a print-it-yourself magazine because you can’t use very large areas of black/colour otherwise people won’t want to print it out (it will cost too much and on some inkjets will make the paper go all wrinkly), so with essentially just black+white and not much opportunity to use large shaded areas you’re pretty restrained – however all that said I think I’ve come up with a layout that works and won’t be too much work to update with new puzzles each issue.  There’s a small sample at the top of this post.

Going forward I imagine most pages will have 4 puzzles on, which seems to work well with the 8″ x 10″ page size.  People ordering a printed copy worldwide from Amazon.com will get it at exactly that size (and will get a bonus colour cover) for $9.99 and eligible for free super saver shipping.  I’ll also make it available in printed form from Lulu.com, which should be cheaper for UK residents – this will cost £5.99, although they add postage costs to this.  Oddly this will be supplied in A4 format due to the page sizes they support, but there’s no extra puzzle content in the extra space!  It will also be available for download, and the 8″ x 10″ page fits very nicely on both A4 and Letter pages without much wasted space.  You can also print it with two pages on one A4/Letter sheet if you don’t mind smaller puzzles, and it’s still perfectly legible and usable.  (I know this – I’ve tested it!).  Download copies will be £2.99 or $4.99 respectively.

PS As mentioned above if you look closely at the Slitherlink puzzles in the sample you’ll see they look suspiciously like Consecutive Sudoku puzzles – that’s because I haven’t substituted the graphics on that page yet! :)

Sudoku Pro issue 50 digital version still online

If you were a subscriber to Sudoku Pro then you can still get hold of issue 50, which so far as I know wasn’t received through the post (but I could be wrong).

Anyway, using Google’s page cache I’ve retrieved the previously-published URL:

http://viewer.zmags.com/auth.php?magid=210247

Note that to use this you will need your subscriber number, which was on the bit of paper with your delivery address. Enter that in the top box, and your surname in the bottom box.

It’s still working as of right now, at any rate.

And here’s the previous issue 49, also thanks to Google: http://viewer.zmags.com/auth.php?magid=198026

I can’t imagine these will keep working too much longer, but who knows?

Sudoku Xtra – a brand new magazine


Sudoku Xtra – The Magazine for Japanese Puzzle Fans

Today someone commented on my blog here about how Sudoku Pro subscribers who get in touch about their magazines are being told that Accolade Puzzles Ltd, the publisher, is no more, so I thought I should comment.

As a freelance puzzle author I get commissioned by a wide range of different publishers, and I don’t work (and never have worked) for Accolade Puzzles, the publishers of Sudoku Pro magazine, so I don’t know any of the gory details. What I do know is that sadly Accolade Puzzles have ceased trading and entered formal insolvency. I also see today that all mention of them is gone from their parent site, Accolade Publishing, and that the Total Puzzles brand site which covered all of their magazines now redirects visitors to the appointed insolvency practitioners

This is very sad news for me, because I always thought of Sudoku Pro as ‘my’ magazine – I wrote literally all of the content for it, from the front cover to the back cover, and not just that but all the little things too such as the puzzles instructions, hints and tips for the puzzle of the month and so on.  Every 4 weeks I sent all of the content off to the publisher and I always enjoyed receiving the magazine in the post, and trying out many of my puzzles anew.

It wasn’t marketing hype when the magazine claimed that the puzzles were hand-made – every single puzzle in the magazine was either entirely hand-made or had a significant manual component. None of it was churned out of an off-the-shelf Sudoku generator, unlike (it will hardly surprise you to know) just about every other Sudoku magazine you can buy. (My top tip for Sudoku puzzles is only to buy content with a named author on it!)  If you’re going to play puzzles created with a free generator someone found on the internet, you may as well print them yourself rather than pay someone else for the privilege. Sudoku Pro was never like that, and indeed the final issues had very few regular Sudoku puzzles in them at all – the majority were variants or other Japanese puzzles.

The final issue, number 50, was available digitally online, so for those who didn’t receive a printed copy you could try checking at the digital version site, if you had it bookmarked (I didn’t, so I can’t tell you what the URL was).  I’m afraid I’ve no idea if any printed copies were ever sent out, but I have a PDF I downloaded from the subscriber’s website just last week so I have a copy of issue 50 myself at least. I’d also sent all of the content for issue 51.

I suppose if the magazine was to end then issue 50 was a good number to reach. Of course I suppose it’s always possible that someone will buy up the assets and continue publishing the magazines, but I have literally no idea how likely that is. I thought their titles were way above the average puzzle mush on the market, and they certainly didn’t deserve to go under.

But this now leaves me with a big magazine gap in my life, and so on to my new project: Sudoku Xtra.

I’ve decided to start publishing a monthly puzzle magazine myself, initially along the lines of Sudoku Pro but then hopefully branching out to a wider range of logic and number puzzle content, and with even more variety.  I’m also hoping to encourage other puzzle authors to contribute.  The magazine won’t be essentially just a UK publication like Sudoku Pro but will be available worldwide for download from a website which  I’m in the process of setting up, and also in a printed version from Amazon.com. The printed version will cost $9.99, to cover the on-demand printing cost, but the download version will most likely be just $4.99. In UK pounds that’s about £2.99, which is pretty much what Sudoku Pro cost. It will be formatted in large page format, at 8″ x 10″, so Amazon-delivered copies will be much larger than book size, and it will  nicely fill the page size for both worldwide (A4) and US (Letter) printers.  If it is successful enough then I will also make it available for order in printed form from Amazon.co.uk and many other sites (an up-front cost I am avoiding until I know I can cover it!). At least to start with it will be entirely black and white, so anyone can print it without trouble.

If you’re a puzzle author and would like to contribute, please get in touch. Initially any money made will go to cover costs so I can’t offer any payment for content other than a free PDF copy, but hopefully I’ll be able to grow the magazine both in terms of readership and content and it will be a worthwhile thing to contribute to and indeed receive. And then going forward, who knows?

Also if this is something you’d be interested in buying then please post here too with any comments, including what sort of puzzles you’d like to see and how many puzzles you’d expect in the magazine (Sudoku Pro had 67 puzzles, plus the four brain workouts on the back page). I am assuming that a monthly (12 issues/year) format would be best, although without any distributor schedule to keep to this could be flexible and shift around slightly.

Perhaps the (probable) end of one magazine can also signal the beginning of something new?

Sudoku Pro Digital Edition

If you’re a subscriber to Sudoku Pro magazine (the best “Japanese puzzle” magazine anywhere outside Japan – although I do write every puzzle in it so perhaps I have some bias; but it really is good) then there’s now a digital edition included free with every printed copy. You can go online with the code printed on your delivery notice and view and print the puzzles out as many times as you like, until, perhaps, you finally solve them! :)

There’s more details and some sample pages on the Total Puzzles website.

PS Sorry I haven’t posted for a while – I’ve had various distractions, both work and family, over the past month, but as of tomorrow hopefully things are going to return to relative normality!

Puzzle Packs/Books for download

I’ve had several requests by email, and a few in comments, about directly selling books or packs of puzzles online – in fact over the past few years I’ve had lots via email from puzzlemix users who want books of particular puzzle types too.

So my question to you is, what format would you expect if you were to buy a collection of puzzles?  There’s no commitment to buy if you comment of course – I’m just trying to gauge what people would expect.  The options I have in mind are:

  • Standard book format, with colour cover and available to print or order a printed copy of.  For example see the two books I put online at lulu a couple of months ago (click through to each title and you can flick through pages of a preview which will give you a good idea of what I mean – they are fully laid-out, ‘real’ books)
  • A simple A4 or Letter-size book format, with one or two puzzles per page and no real page design other than puzzle and/or page numbers, available for online download only.
  • A zip archive file with lots of separate PDF files, just as you might download individual PDF puzzles from this site.

Also I’m wondering what size of collection would interest you?  I’ve always tended to put 100 of a puzzle together before, but perhaps 50 would be a better quantity and then I could also create regular updates for popular packs with new puzzles every month or two, depending on demand?
