Normal killer cage sudoku rules apply. Numbers must not repeat in a cage. The numbers in the cage must sum to the given total in the top left corner.

Numbers along an arrow must sum to the number shown in the circled cells.

Numbers along a between line must be between the numbers on the circled ends of the line. (Between lines that intersect in this puzzle, do not turn, they continue in a straight line.)

Numbers that appear in the cells between a ratio constraint must have a ratio of the indicated number. If no number is entered, the ratio will be assumed to be 2.
