BrainSnack® Sudoku
Intro
Sudoku has conquered the world in no time, and it’s here to stay. The puzzle’s attraction is easy rules combined with reasoning that is sometimes quite complex. Sudoku is even recommended as an exercise in logical reasoning.

For a 9x9 grid, a computer can generate about 6,670,903,752,021,072,936,960 different Sudoku puzzles. However, “only” 5,472,730,538 of them are correct Sudokus after taking into account symmetries, rotations, double solutions, and unsolvable elements. This means that only a small portion of computer generated Sudoku puzzles are correct.

To guarantee the quality of our Sudokus, we have created our own program in .NET C#. It uses three different logical strategies to solve the puzzles: Excluding, Situating and Securing. These three strategies only use logical thinking (no guesses). You can solve any Sudoku, whether it is for beginners or experts, with these three strategies.

Directions
Fill in the grid so that each row, each column and each 3x3 frame contains every number from 1 to 9. Sudoku Mini works with smaller frames and 6 numbers. Sudoku Max has larger frames and 12 numbers.

Availability
We can generate an almost infinite number of Sudoku games for kids (aged 8 and up) and adults. Difficulty levels can range from beginners to experts, with a grid size of 9x9 to 12x12. Click on the links below to see some samples. Technical
