*** TODAYS PUZZLE ***
An incredible discovery tonight courtesy of Aad van de Wetering who has somehow worked out that, if you place a Necker Cube in a sudoku grid, and add a couple of digits at the vertices then you can create a unique sudoku... This is a STUNNING construction and a delight to solve. One of the all-time classics.
Play the puzzle at the links below:

Rules:
Normal sudoku rules apply. Neighbouring digits on the orange line must differ in value by at least 4.
