This is the second volume of the serie Sudoku 3D Challenge. If you like Sudoku puzzles, you would like Sudoku 3D. It is a Sudoku in the shape of a cube where the digits on any face affect the resolution of the other faces of the cube. The third dimension means that all the columns and rows are not in straight line, like traditional Sudoku, but span two faces of the cube. In this book you will find Sudoku 3D puzzles in various sizes from the 4X4X4 cube, through the tough 6X6X6 cube, up to the Dantean challenge of the 8X8X8 cube. Also, in order to move out of our comfort zone, some cubes have irregular regions like jigsaw Sudoku. You will also find, as a bonus, Hyper Sudoku 3D puzzles which are an amalgamation of many cubes interacting together. At first sight these puzzles seem intimidating, but, don't worry. You need the same skills as required by an ordinary Sudoku puzzle to solve Sudoku 3D puzzles; it is just...more enjoyable. Each of these puzzles would please you. Don't wait to try the Sudoku 3D challenge
