Sudoku is one of the favorite mental entertainment of many people, but computer scientists will not waste paper. They will use the PC version of the popular game known from newspapers or special publications. One of the most valued projects of this type is a work simply called Sudoku, once spreading as Papppocom Sudoku.

After many years, the commercial product was finally made available for free. The rules of play remain the same, of course, as in the paper version. By default, we get a grid of 9 squares of 9 fields to be filled with digits from 1 to 9.

Some digits are immediately placed in grids, the remaining ones should be entered in such a way that in each column, row and single square no digit repeats itself. Production offers several levels of difficulty, and in addition, it is possible to modify the size of the whole grid to be able to headed, for example, with a dozen or so rectangles to complete. The game offers a simple but clear interface, fully supported by the mouse, which can be additionally modified in the options.

Puzzles are generated randomly each time. There is a function of transcribing numbers from a paper sudoku, if someone particularly liked a newspaper variation of the game. It is also possible to do the other way, i.e.

to print a generated grid to be filled with a ballpoint pen. In order to unlock the full capabilities offered by Sudoku, you need to enter a special free license key in the Enter Key... from the File menu:
