Normal 6x6 sudoku rules apply. Draw a path through every cell in the grid, which only moves orthogonally and doesn't visit any cell more than once. The start and end of the path are to be determined. The value of a cell equals its own digit plus the sum of all the digits visited before it. A pink clue in a cell indicates its value. If a black dot sits between two cells, the VALUE of one is double the VALUE of the other. If a white dot sits between two cells, the VALUES of the two cells are consecutive.
