Hi Folks,
This is my first post here but I'm not new to Sudoku. I was wondering if anyone knows the origin of the puzzles in Carol Vorderman's book, "Massive Book of Sudoku"? Her other book "Master Sudoku", credits Nikoli in association with Puzzler Media as the supplier of those puzzles but in the "Massive..." book, it only says that the text is copyrighted by her and the puzzles by Puzzler Media, with no mention of Nikoli.
Does anyone know if those puzzles are also Nikoli puzzles and/or if they're handmade?
