Normal sudoku rules apply.
Draw an orthogonally connected loop that does not branch or cross itself. Digits along the loop are ascending or descending, with 1 and 9 reversing the direction. Each 3x3 box has a different number of loop cells.
Grey squares contain even digits and grey circles contain odd digits. Neither grey squares or grey circles can be on the loop.
Cells separated by a black dot have a 2:1 ratio, and at least one of the two cells is on the loop.
