Simple Sudoku 4.2.1.83

Simple Sudoku is a simple yet complete sudoku puzzle with multiple options. It has 5 levels of difficulty, but only one board 9x9 size. The board can be maximized 14 times, and you can customize the general and marker colors. The user interface is simple, and it is available in 19 languages. However, it has no music or sound effects. In case you get stuck or if you are simply a beginner, you can use hints, undo and redo options, filters, markers, and you can also block invalid moves and show possible candidates. All the puzzles can be saved and also printed to take them wherever you go. However, It doesn't include a puzzle creator to check those puzzles of magazines or newspapers, and the method of entering the numbers to the board is weird and uncomfortable.Moreover, when you right click a cell to select the number you want to insert, the program indicates you the possible candidates for that cell, which makes the game really easy, no matter what difficulty level you selected. I think this game could only work for novice players, since more advanced players will find it boring and plain.
