HOW TO

Sudoku is a very easy game to learn but it also provides a very deep challenge that requires logical thought and concentration, though not necessarily mathematical skill.
Each puzzle consists of a grid of boxes (or 'cells'), into which you must write the numbers 1-9 in each horizontal line ('row') and vertical line ('column'), and also within all the small groups of cells ('3x3 blocks') indicated by bold lines. The challenge lies in the fact that each number from 1-9 must appear only once in each column, row and 3x3 block. (For more detailed rules, see the Rules of Sudoku section.)
While the size of the Sudoku grid always stays the same (9x9 cells), each puzzle is different because of the 'given' numbers that are already provided in a few of the cells to start you off. Players need to employ a process of elimination to work out which numbers go where.
Sudoku is normally played with a pen or pencil, on grids printed in
newspapers and puzzle books, but Sudoku Master for Nintendo DS brings
technology into play while still maintaining the simple playability of
the paper-based original.

Sudoku Master has more than 400
built-in puzzles that you play using the Nintendo DS's touch-sensitive
screen and stylus, just like a pen and paper. To enter numbers in
cells, you simply touch the cell you want and then tap the chosen
number on the on-screen keypad. Alternatively, you can write the number
by hand on the screen and it will be recognised instantly by built-in
handwriting recognition software. |
