Sudoku 16×16 Volume 1 – Sudoku Xtra Specials
Feb 15th
A book of just 16×16 Sudoku is now available both for download or in pre-printed form from Lulu.com or Amazon.com (with free delivery in some cases).
I’ve had lots of requests for a book like this over the past couple of years, so I hope if you’re one of the people who’ve wanted something like this that the book meets your expectations! All of the puzzles have nice symmetry, and the difficulty level is set such that you won’t need to make lots of fiddly pencil marks in the grid (or indeed any pencil marks at all, if you don’t want to).
It’s printed on large paper (A4 at Lulu, 8″x10″ at Amazon), with just one puzzle per page, so you’re getting the puzzles at a comfortable size for solving. Full solutions are included, and with 50 puzzles it’s going to take you a long time to solve them all!
Please feel free to post any comments here, or head over to Sudoku Xtra and take a browse on the discussion forums – and maybe join in!
Sudoku Xtra Specials: Sudoku 25×25 Volume 1
Feb 5th
I’ve had many, many, many requests over the past years for a book of giant 25×25 Sudoku puzzles, so I have now finally made just such a book available!
Right at the moment it’s only available in printed form, but I’ll have download copies available in the next couple of days – as soon as I’ve added a purchase mechanism to SudokuXtra.com in fact!
I’ve decided that I’m going to make a series of similar books of particular requested puzzles, all of which will be branded as “Sudoku Xtra Specials”. In this way I can stay organised by keeping all of my download/printed content under the ‘Sudoku Xtra’ heading. It means that you’ll always be able to find all of my new content in one place, without searching around my various sites.
This book is probably the nicest collection of 25×25 puzzles you can find, if you’re a fan of such things. Every puzzle has really nice 8-way symmetry – having noticeable patterns in puzzles like this is pretty unusual, and it can help with the solve too. Just as in my magazines, I’ve thought about what’s sensible in a puzzle like this so they can all be solved without needing pencilmarks. How exactly would you go about making A-Y pencilmarks in each individual square anyway?!
If you get hold of it please do let me know any thoughts you have on it. In the same way as for Sudoku Xtra magazine, it’s designed to be printed at home on either an all-together or a page-by-page basis. And if you get a pre-printed version from Lulu or Amazon.com (already complete but waiting on listing now) then it’s on a large A4 (Lulu) or 8″x10″ (Amazon) page, so there’s plenty of room to write in the solutions.
If there are other books of puzzles you’d like to see, please let me know in the comments here or on the Sudoku Xtra forums – feel free to repeat any requests you’ve made before! Next up is 16×16 Sudoku but after that it’s all open. I was thinking of doing Inequality Sudoku third, but what do you think?
Barnes & Noble
Feb 4th
I was interested to spot that Barnes & Noble (in the US) are now selling one of my self-published books – Killer Sudoku: 100 easy to hard puzzles and how to solve them.
So if you’re in the US and fancy getting hold of a copy (they get really hard by the end!) then there’s now another way to buy it. You even get 10% off if you’re a member. 
The Little Book of Hard-as-Nails Sudoku 5
Jul 22nd
My new book is out now – The Little Book of Hard-as-Nails Sudoku 5
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!
