zonSoduku is a very simple application that allows you to generate random sudoku games. The goal of any sudoku game is to fill the board with numbers from 1 to 9 in a way that every column, row, and 3x3 square has no repeated numbers. The application includes three board sizes (4x4, 9x9, and 16x16) and five different difficulty levels to choose from. The difficulty level of a sudoku game is determined by the numbers it has on the board when you start a game. The more numbers, the easier the game is. If you get stuck, you can use the hints, which are unlimited, and will add one number to the puzzle.
All the games are timed, so you can keep a record of how long it took you to complete a puzzle. The game also offers an option to show the errors, so you can correct them. Unfortunately, the application features very simple graphics and it doesn't include sounds or music. Moreover, you won't be able to mark numbers with a pencil, print empty puzzles to take them wherever you go or check your own puzzles.
In short, if you are looking for a free and simple sudoku game to pass the time, zonSoduku may help you, but don't expect too much from it.
