Here is a sudoku puzzle with a "fantastic" ruleset.

RULES: There are two grids, the real grid that you see and an imaginary grid behind it. Normal sudoku rules apply for both. The cells that have different digits in these two grids contain the difference between these digits as a small clue at their top left corner. The white dot separates two consecutive digits in the real grid, but it looks black and separates two digits with 1:2 ratio in the imaginary grid.

Here is a 4x4 example for clarifying the ruleset.
