PUZZLE:

---

---

RULES:

---

"Normal" Schrödinger rules apply.
(i.e. place the digits 0 through 9 once each in every row, column and box;
two of the digits will have to share a Schrödinger Cell;
each row, column and box contains exactly one Schrödinger Cell).

• Killer: Digits within a cage must sum to the number in the top-left corner (if given).

---

MODIFIER:

---

• Schrödinger Certainty (Natural): No Schrödinger cell will contain a '0' digit.
• Stadiometer: From left-to-right, the digits of each Schrödinger cell indicate the two possible row locations of the Schrödinger cell in the next column (e.g. if there is a Schrödinger cell at R1C1 that is a 4/8 pair, there is a Schrödinger cell at either R4C2 or R8C2).

Note: Column 1 is to be considered to be to the right of Column 9 (i.e. the Schrödinger cell in Column 9 will index the Schrödinger cell in Column 1).

INTRODUCTION:

---

This should be a more approachable take on a previous puzzle involving Schrödingers and the Stadiometer constraint (go check out "The Dagwood" for a nice intro to Stadiometers; or if you've mastered this puzzle with ease, go and tackle "Split Decision" for a much greater challenge).

Thank you efnenu, for the testing and quality control!

Here are some puzzles from other setters using a similar constraint:
"Hell's Bells" by Christounet
"Schrödinger's Triplers" by Oddlyeven

Have fun!
