Solve on Sven Neumann’s Sudokupad: Multiplying Arrows for Puzzle Patzer

BACKGROUND: Puzzle Patzer is a YouTuber who has solved several of my puzzles. He recently solved a 6x6 puzzle with the arrow product rule and someone commented they would like to see the rule in a larger grid. Puzzle Patzer replied “Yes it would be interesting” so in the interest of being interesting I set this puzzle.
