Every 9x9 bi-dimensional schema must be solved, keeping in mind that every single cell belongs to the selected schema and also to the other two placed on the orthogonal planes. With 4 difficulty levels and 4 initial values distributions, you can customize your game and have every time a new exciting challenge to solve.
