For those not in the know (as was the case with this reviewer), Sudoku is in essence an old-school brainteaser challenge. Players are presented with a grid, in which each column, row and 3x3 square has to have the numbers 1 to 9 (with no repetition). Grids start off with only a few numbers scattered throughout, with players required to use their logic and reasoning to fill in the blank spaces.
The PSP's Go! Sudoku is a straight up and down rendition of the puzzle. There's no wacky new game modes or cutesy player avatars here - it's just the grid, the numbers and your brain. The only bit of flair to be found is in the varying grid backgrounds (with themes such as fire, earth or air), but apart from that it's Sudoku at its simplest. Fans will love it.
And there's plenty of Sudoku here for fans to enjoy. The game features 1000 puzzles of varying difficulty (easy, mild, difficult and fiendish), with 200 more free to download from www.yourpsp.com.au. The game itself has survived the transition from paper to PSP well - while you can't pencil in possible answers as you can with the paper-based puzzle, Go! Sudoku does allow you to fill in blank spaces with tentative answers which you can then fill in later.
Go! Sudoku also gives players the option to change the game from being just a solitary past time with the addition of multiplayer modes. Up to four players can play the game wirelessly, while Go! Sudoku also has a game share feature where up to five puzzles can be shared with another PSP. For those whose friends are PSP-less, the game also has a Pass mode which allows a multiplayer game to be played with one unit.
If you're one of the legions who can't get enough brain-busting Sudoku fixes, then Go! Sudoku's faithful rendition of the game plus the hundreds of puzzles available make it a must have. Its budget price of AU$49.95 is another sweetener.
