Sudoku-7 is a puzzle game that enhances logical thinking, imagination, and patience. It features simple rules and provides an enjoyable experience for players, who can develop their problem-solving skills.

You can play the game at one of seven difficulty levels, from beginner to expert, and you can save and load games. But that's not all - Sudoku-7 also allows you to customize the appearance of the Sudoku board itself. You can change the scale and skin of the board, with seven built-in skins to choose from and even an option to use an external skin.
But what really sets Sudoku-7 apart is the ability to create your own skins with the included "Skin maker" tool. No matter what your personal style is, you can make the board look the way you want it to.
And that's not all - you can also modify the appearance of the non-game part of the window, such as the background, tone, and cursor color. You can choose whether or not to display the moves list, and even enable the coordinate readout if that's more your style.
If you want to take your Sudoku game to the next level, you can print out the game board itself. With Sudoku-7, you have everything you need to customize your Sudoku experience and make it as fun and challenging as you want it to be!
