Kropki 3D Sudoku

Sudoku on a cube, with hints !

Sudoku just left the page. Kropki 3D Sudoku wraps the classic logic puzzle around a cube: six faces, each a 3×3 grid, linked by white and black Kropki dots that carry clues across the edges. A white dot means consecutive numbers; a black dot means one doubles the other.
