This is now my third puzzle in a row with the new Zipper Lines constraint by Jaze. It uses some concepts of the 6 by 6 but on a larger grid. Hope you enjoy!

• Normal sudoku rules apply.
• Digits an equal distance from the center of a lavender 'Zipper Line' must sum to the digit in the middle of that line.

Example Puzzle

Here is a 4 by 4 example from Jaze (left) and it's solution (right). Notice how the ends of each line sum to the digit in the center of the line. Additionally, the long line also contains two more sums 4=1+3=1+3=2+2. You can play the example here.

Difficulty

According to the testers on the CtC fan discord (thanks everyone) this puzzle sits on the upper end of 2 stars. It is definitely harder than my previous zipper puzzles.
