YOUR VACUUM CLEANING ROBOT SUCKS.

Normal 6x6 Sudoku rules apply. Place the digits 1-6 exactly once in every row, column, and 2x3 box.

Find the correct path that connects both circles.

Our imaginary vacuum cleaning robot has one path it always takes to clean the entire grid as efficiently as robotically possible. The robot moves strictly orthogonally and visits every cell in the grid except for the caged cells. The path can not cross any walls nor cross itself.

Adjacent digits on the path can only have a difference of 1 or 2.

Digits separated by a black dot have a 1:2 ratio, meaning one is exactly double the other.

Have fun.
