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.
