Thanks to TopAutism, The Book Wyrm, Martijn and Lenzoli for helping me make this possible and thanks to The Book Wyrm and Aletheia for testing.

Rules:

This 3x3 of cells are a part of a standard 9x9 sudoku grid and can be located anywhere in the grid. Fill the 9x9 sudoku with digits from 1-9.

Killer cages: Digits in a cage cannot repeat and must sum to the total in the top left corner of the leftmost cell in the top row of the cage. All cages have a cage total.

Arrows: Digits along an arrow sum to the digit in the arrow's circle located at the opposite end of the line as the arrow tip. Arrows do not touch or cross themselves or other arrows (Two arrows never enter the same cell). Arrows do not branch (Only one arrow per circle).

Row indexing: The entire grid is row indexers. Digits in row X indicate the row in which the digit X appears in that column. For example, if r3c6 is a 8, r8c6 is a 3.
