Sudoku

Sudoku is a logic puzzle game. The goal is to fill the complete board with numbers. Every number may only occur once in every column, row and subsection.

There are 3 different game modes :
1. a 6x6 game field with 2x3
2. a 9x9 game field with 3x3
3. a 12x12 game field with 3x4

There are 3 different difficulty levels, that are not measured by the number of set values but rather by the solving strategies needed to solve the game. The generator always tries to provide a game that has the minimum amount of set values, that are needed to solve the game.
