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 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.
