INTRODUCTION:

---

This one came together rather quickly, after the initial inspiration. There's more to explore here with the concept, I think; for now, I hope this serves as a good introduction to the logic. As an aside, in my head I think of these as "Zifference" lines and I was sorely tempted to call these "Ziffmometers" but if I did I'm fairly certain I would break poor Marty Sears's heart (so no one tell him - we'll just keep this our little secret).

Here are some puzzles from other setters using the same constraint:
"Same Zifference" by Marty Sears
"Zipper or Ziffer?" by ThePedallingPianist, Marty Sears and ViKingPrime

Have fun!
