Real Sudoku3D Pro

This game creates a truly realistic 3D Sudoku experience. Regular Sudoku is played on a 9 by 9 grid but Real Sudoku3D uses 9 layers of 9 by 9 grids.

All the layers follow standard Sudoku rules, whether viewed as faces (from front to back), levels (from top to bottom), or slices (from left to right).
The game interface lets you dive right in and see the game from any perspective. You can turn and move the game around, zoom in and out, or fly straight through. Also you can select a cube to enter your choice of number, or make notes on which numbers remain possible.
