Arrows. Arrows everywhere! 

In this video, Timotab solves Gridlock by The Book Wyrm.
You can try this puzzle for yourself using Sven's Sudokupad here: sudokupad.app/...
Rules:
• Normal sudoku rules apply.
• Digits along an arrow sum to the digit in the circle. If there are multiple arrows from a circle, each is counted separately.
