Sudoku Generator Free description

Sudoku Generator Free is a very simple, but powerful sudoku generator.
It's not just able to create any single possible 9x9 sudoku in the world, but also introduces some features to add some fun, such as daily sudoku, leaderboards, top 1000 hardest sudokus, and more!

You can generate sudokus using 4 different techniques:
Linear will remove all possible cells, going from one line to another. This technique ensures that there is a completely empty line.
Numeric will remove all cells with a value, from one value to another. With this technique it is ensured that there is no shown number of at least 1 of them.
Random will delete cells in a totally random way. It is capable of creating any possible sudoku.
Symmetric will remove cells symmetrically and offers 4 options: 4 corners, 2 sides, 4 corners + 2 sides and the 4th option, which after making the 4 corners and the 2 sides, will break the symmetry trying to eliminate single cells to increase difficulty.

It also features a visual editor to let you set your very own style. Preview images will look as you want too!
