Description

In writing Mystery of Sudoku I had an idea about creating an exceptionally hard puzzle. The result of this endeavor is a wide range of DDT puzzles, some of which will be included in this collection. DDT puzzles are another variant of Classic Sudoku puzzles, All FIELDS contain GIVEN NUMBERS whereby up to nine numbers can be given in a single FIELD. Despite similarities, familiarity with Classic Sudoku Rules is not necessary as during the solving process, all CORRECT NUMBERS are obtained, using only DDT RECTANGLE (). There are easier and harder puzzles to suit everybody's taste and preference.show more
