There is also a prize spiral crossword every day, so get your pencils ready!

April 1st Sudoku

Wow, it is a long time since I posted here. So much to do, so little time!
I might as well keep it brief now, then. Here’s a puzzle for April 1st (it’s actually a normal puzzle without tricks – it just spells ‘FOOL’ in the given numbers). Place 1 to 9 in each row, column and bold-lined box.


Sudoku April 1st puzzle
Wow, it is a long time since I posted here. So much to do, so little time!

I guess that means I might as well keep it brief now, then. On that basis:

Here’s a puzzle for April 1st. It’s actually a normal puzzle without tricks – it just spells ‘FOOL’ in the given numbers. Like any Sudoku, simply place 1 to 9 in each row, column and bold-lined box.

Box-Jigsaw Sudoku


Sudoku Box-Jigsaw 9×9 1 puzzle
I haven’t posted a puzzle for a good while, so I thought it was time to fix that with this Box-Jigsaw Sudoku puzzle.

The puzzle combines regular Sudoku with Jigsaw Sudoku. Just place 1 to 9 once each into all of the nine rows, columns, 3×3 boxes (indicated by both shaded and unshaded background areas) and bold-lined jigsaw regions.

New 3D Sudoku book

101 Jumbo 3D SudokuA brand new book, packed with 101 Jumbo 3D Sudoku, is now available for purchase from Amazon. You can either search for this directly, or you can click through via my PuzzleBooks.org site – the book is at the very bottom of that page, and clicking on it will take you direct to the correct page on your nearest Amazon store.

If you’re not sure of the rules, or haven’t seen one of these puzzles before, then check out the example puzzle I posted last week.

Jumbo 3D Sudoku


Jumbo 3D sudoku puzzle
I haven’t posted for a while so I thought I should post one of my new puzzles. This one is a Jumbo 3D Sudoku, where the aim is simply to place 1 to 9 into each black-lined 3×3 area as well as each of the 54 rows indicated by the coloured lines. Thick black lines indicate borders where the rows don’t continue.

There’ve been 3D sudoku around for a while, and in terms of solving there’s little difference from regular sudoku except for the increase in size and the way in which the bendy regions can easily cause you to miss an “obvious” deduction! This is the biggest I’ve seen, but it’s perfectly possible there are larger ones I’m not aware of.

Anyway, if you’re a fan of samurai sudoku or any other kind of large sudoku then you should enjoy this, I hope!

Average solving time is around 1 hour.

Product Killer Sudoku


Product Killer Sudoku 9×9 puzzle

If you’re interested in sudoku, come along to the official UK sudoku championship next weekend, the 29th-30th of March, at Selsdon Park Hotel just south of London, outside Croydon. There’s full details on the UK Puzzle Association site. There’s still spaces available.

Mind you, it’s not just sudoku – there’s also the UK puzzle championship taking place the same weekend, and there’s a low price which includes overnight accommodation and most meals for those who take part. Winners of both events get the chance to represent the UK in the World Puzzle Championships and World Sudoku Championships.

One of the puzzles in the sudoku part of the tournament is Product Killer Sudoku, a variant on Killer Sudoku where multiplication, rather than addition, is used.

So: just place 1 to 9 once each into every row, column and bold-lined box. Also place numbers in each dash-lined cage so they multiply to the given total. You also can’t repeat a number within a dashed-line cage.

Valentine Sudoku
