Sudoku is an addictive number puzzle that challenges users to fill in the missing numbers based on the numbers that are present; each of nine grids must contain the numbers one through nine once, as must each row and column of the playing board. The premise is simple, but the game can be quite a challenge. Sudoku Portable is a lightweight version of this popular puzzle that's made to be used on USB drives and other portable devices (although it works just fine installed on a PC). It's not fancy, but it does deliver the fun--and frustration--of traditional sudoku.
Installing Sudoku Portable is easy, although users will have to specify the installation location. The program's interface is plain, with the numbers arranged on a gray grid board. Entering numbers is as easy as clicking in the appropriate square and entering the desired number on the keyboard. When the puzzle is completed correctly, the board turns green. Users can check their work at any point during the game, and incorrect numbers will be highlighted in yellow. The game can also automatically solve the puzzle if you get stuck. There are four levels of difficulty, ranging from easy to impossible. A built-in Help file is brief, but does a good job of explaining gameplay. Overall, Sudoku Portable didn't wow us with its features, but it was is an enjoyable, lightweight rendition of this popular game.
Sudoku Portable is free. It installs and uninstalls without issues. We recommend this game to all users.
