Sudoku3D 2: The Cube

Sudoku3D 2: The Cube is a Sudoku game played on cubes. You can choose a cube size from 3³ to 9³ and a difficulty level from 1 to 9, corresponding to an analogue of the probability of an empty cell ranging from 10% to 90%.

As difficulty increases, puzzles may have several solutions, but only the originally generated solution is considered correct. The usual rule of 3×3 subgrids within a 9×9 grid does not apply because the cube size is selectable.

Ghost cubes

Ghost cubes can confuse you by turning numbers. A scanner can reveal them, but you can use it only once per session.
