Sudoku Master - DS/DSi

Sudoku Master for the Nintendo DS contains more than 400 Sudoku puzzles and allows gamers to play a different game at any one time. If you have not played Sudoku before, the rules are straightforward enough. The aim of the puzzle is to enter a number ranging from one to nine in each cell of a nine by nine grid, made up of nine three by three sub-grids. Each puzzle starts off with some numbers already provided in a few cells - these are the hints. As the puzzles increase in difficulty, players will find the number of hints given decreases. It is then up to the player to make sure that each row, column and three by three sub-grids have only one instance of each number. To be a success, Sudoku Master requires both skill and patience in abundance from the player.

The game has three difficulty settings, so gamers of all abilities will be able to pick up and play. For those players who are new to Sudoku, there is a Practice Mode where numbers that are entered incorrectly automatically turn red, telling players that they have entered the wrong number. There is also a tutorial that explains the rules of the game as well as offering some invaluable tips that will undoubtedly be of use.

Using the Nintendo DS touch screen, players have two ways of entering the numbers into the cells: they can write them in or select the appropriate number by touching the keys on the number pad. When players solve puzzles successfully, they also earn stars. The faster a puzzle is solved, the more stars a player will earn. When enough stars have been earned, players will gain access to what is called Rank Mode. Here they must complete various puzzles in a set period of time and are awarded a rank accordingly. Therefore, the faster the puzzle is completed, the higher the rank awarded.
