Yesterday I received an email from David Chipping about the launch of his SudokuWorld website (available in English and Dutch).
It’s comprised of millions of unique, self produced Sudoku’s that all have one unique solution. The Sudoku’s are produced using a comprehensive method of pattern matching to have fun and intriguing puzzles.
SudokuWorld was launched with 1,000,000 puzzles but has continued to add to this throughout its up-time to provide millions more. They have one of the largest collection of Sudoku’s online today and offer a website service completely free of charge.
Currently the website offers two ways of Sudoku variants : web based puzzles including Safe For Work Sudoku Puzzles. SFW Sudoku’s are a variation upon which a Excel spreadsheet screen emulates business activity, while offering fun Sudoku playing (to be clear : by this I do not promote solving Sudoku’s during working hours).
Second to this, SudokuWorld offers a continuously expanding set of e-Books which are available as downloadable PDF’s. Each book contains a set of unique Sudoku puzzles and are provided completely free of charge. Happy Puzzling!
