Be prepared for the ultimate brain exercise!

Sudoku-Ball extends the 2 dimensional samurai Sudoku to closed 3 dimensional objects such as cubes, spheres and other geometric shapes. This adds a challenging new dimension to the Sudoku puzzle as not only you have to solve each individual Sudoku by its inter Sudoku logic but also you have to take the neighbouring and adjacent Sudokus into account to solve the entire object.
