The final frontier in Sudoku puzzling.

The book contains 78 triple-sudoku puzzles. Each puzzle consists of a composition of three regular sudoku-grids on the sides of a cube, sharing one set of 3 by 3 boxes. Like any regular sudoku, each puzzle already contains some numbers in a fixed place which may not be altered.

The beauty of triple sudoku is that it is an entirely new sudoku phenomenon, where partial solving of one of the sudokus can mean finding clue to the further solution of the other sudoku.

It is even more sudoku-fun!
