Macdoku is a simple application that allows you to create simple sudoku puzzles to play on your computer or print them to take them wherever you go. The program includes four difficulty levels to choose from and it has the ability to generate a random puzzle any time you want. In case you don't know the game, sudoku is a puzzle game where you need to complete every column, row, and 3x3 area with numbers from 1 to 9, that cannot be repeated.
The game also offers multiple help options for beginners. You can display possibilities, highlight possible cells, highlight invalid moves, and highlight solved cells. You can also customize the cell, cursor, and misc colors. A great thing is that the games can be saved to continue them later and you can also enter your own values to check the solution of any puzzle you want, for instance, one you solve in a magazine. The game offers simple but attractive graphics, but no sounds or music.
All in all, if you want a simple puzzle generator and checker, Macdoku can be a good choice.
