Normal sudoku rules apply.

Place the digits 1-9 once each in each row, column and box. Zipper lines, arrows, and killer cages are all present, but they work a little differently here. Where their rules would usually concern addition, they concern multiplication here.

To clarify:

- For lavender zipper lines, digits an equal distance from the centre multiply to the centre digit. For even-length zipper lines, the middle two digits can be read as a 2-digit number, read either left-to-right or downwards. For example, 643696, if allowed by sudoku, is a valid zipper line, since 6x6 and 4x9 both equal 36, the middle 2 digits. Digits can repeat on a zipper line.

- Digits along an arrow multiply to the number in the pill, read left-to-right or downwards. Digits can repeat on an arrow.

- Digits in a killer cage multiply to the digit in the top-left corner. Digits cannot repeat in a cage. Good luck!
