Normal sudoku rules: Every row, column, and box must contain a complete set of the digits 1-9.

Cages: Digits in cages cannot repeat and must sum to the value shown in the upper left corner of the cage.

Zipper Lines: Along Zipper lines, pairs of digits equidistant from the center of the line have the same sum. For Zipper lines of odd length, that sum is the central digit on the line.

Wow, what a wonderful puzzle! Took almost an hour to solve, mostly at the start trying to figure out how to use zipper lines. Satisfying solve!

Loved the way the zipper lines interacted with the killer cages. Thanks for sharing!

Took a bit of thinking to get onto the right wavelength for the opening, but once I got the concept the rest flowed in a lovely way.

Thank you for this fantastic zipper/killer puzzle, FullDeck-Missing! I found the break-in (which is just lovely by the way) relatively quickly, but then missed a lot of stuff that felt so forced and well-telegraphed in hindsight. But even given my oversights the solve was thoroughly enjoyable. Thank you for setting and sharing!
