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.
