Sudoku is a popular puzzle game where the main goal is to fill a board of 3x3 regions with numbers from 1 to 9. SudokuAdept is a program that brings you dozens of Sudoku boards for you to solve. It's great to play it while relaxing on a break from work or to test your Sudoku skills.
You have access to five levels of difficulty, therefore, if you're a beginner, you can start playing the Very Easy mode first and advance as you learn more how to calculate your moves. This program allows you to save game progress and undo moves.
SudokuAdept not only provides you with brainteasing puzzles, but also lets you create your own. The built-in Sudoku editor allows you to build unique games to share with your friends.
A thing I don't like about SudokuAdept is that the font for the entered numbers is too small and the program doesn't have any font configurations available. Another disadvantage of using this program is that Fill In All Possibilities and Auto-Reduce Possibilities don't work.
Briefly, if you can ignore the aforementioned flaws and just rely on the fact that you have access to numerous Sudoku games, I say it's worth trying SudokuAdept.
