Website feature-ready

I’m happy with where the Sudoku Xtra website has got to now, with another update today pushing on all the material I wanted.  It will I’m sure need further work when there are multiple issues available, but for now it’s more than good enough I think.

As mentioned yesterday, the most exciting feature (other than being able to view and buy and read about the magazine!) is the new discussion forum.  It’s a pity Sudoku Pro never had one, because the old BBC MindGames one (which incidentally featured a large number of my puzzles too) was always great.  It would be brilliant if we could make the Sudoku Xtra forums just as good! Here’s hoping…

If you’ve got issue 1 (or even if you haven’t!) please feel free to let people know about it – building up a readership is of course an important part of launching a new magazine, particularly one that won’t be on shop shelves any time soon! :)

Discussion forums for Sudoku Xtra

Thanks very much to everyone who’s bought Sudoku Xtra issue 1 so far – I really appreciate it, and thanks also for your great feedback!

I’m still working on adding content to the main Sudoku Xtra site, which of course it was more important to get up and running at all in the first place rather than waiting until it was ‘finished’ to launch, and so today’s big addition is a discussion forum!

Please feel free to continue posting here about Sudoku Xtra if you would prefer, but if there’s anything you’d like to open up for discussion – or just want to chat about a particular puzzle (or even ask for help solving one!) – then the forums are probably the best place to do it.

You don’t need to register on the Sudoku Xtra site in order to post to the forums, but if you don’t you’ll be asked to type in one of those anti-spam image things each time you post – but I’ve made sure they’re very legible, so conversely fingers-crossed there won’t be any nasty problems with spam! (You should see just how much gets caught in the anti-spam message filters for this site alone – it’s quite astonishing!)

Thanks again!

SudokuXtra.com magazine downloads

Well, www.sudokuxtra.com is now live – live enough that you can now go there and buy the magazine and get it immediately. So what are you waiting for?! :) As I posted earlier, there’s also a preview copy you can download if you want to check out some of what you’re getting first.

I’ll also be adding more content to sudokuxtra.com over the coming week, including a discussion forum.

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.

Click here for a printed copy of the magazine: Sudoku Xtra issue 1 on Lulu

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! :)

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?

The Little Book of Hard-as-Nails Sudoku 5

My new book is out now – The Little Book of Hard-as-Nails Sudoku 5, from Michael O’Mara. It’s available from Amazon UK (link on the right) and, as they say, all other good book stores! (For now, it’s UK only, although importers have listed it on Amazon.com already). It’s part of the Little Book of Sudoku series, thus the number 5 on the cover (although confusingly it’s actually the 6th Little Book of Sudoku, since there was one by another author with the prefix ‘Quick’).

It has 201 puzzles of ever-increasing difficulty, starting at tricky and progressing to insanely hard. They’re broken down into 5 levels, each requiring additional solving skills, but within each level they also get tougher as you progress. Although the puzzles really do get very difficult, they never require ‘unfair’ logic or obscure solving techniques that you’d be unlikely to come up with just on your own. Take a look at my previous posting on hard sudoku for an example – although they get harder than this in the book!
