The Sudoku Extend software module features 7 additional boards for the popular puzzle game, available on the website of New Logical Games.

It should be noted that the game blocks are designed for screen resolutions of 1280*1024 or higher. So, those with smaller screen resolutions may not be able to utilize this feature. It's also important to mention that these additions can only be installed on an already installed game program.
Overall, I would definitely recommend downloading the Sudoku Extend module, especially if you're a fan of the game and want to expand your collection of boards. The game blocks are also a nice bonus and can enhance your overall gaming experience with other games offered by this developer.
