PUZZLE:

---

RULES:

---

"Normal" Schrödinger rules apply.
(e.g. 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. Digits must not repeat within a Killer cage.
• Kropki: White dots separate two cells containing consecutive digits; Black dots separate two cells where one digit is double the other [ratio of 1:2] (not all dots are given).

---

MODIFIERS:

---

• Schrödinger Certainty (Restrictive): If a Schrödinger cell falls within a Kropki dot, both digits must satisfy the condition (i.e. both be consecutive with or both be in a ratio of 1:2 with the digit in the adjacent cell).
• 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:

---

A puzzle dedicated to the wonderful Christounet, whose work with Schrödinger cells is always inspired, eminently challenging and yet somehow completely approachable (do yourself a favour and go explore their back-catalogue!).

I want to especially thank SirWoezel for helping to get the puzzle down to a unique solution.

Here are the other entries in the "Stadiometer" series, for those interested:
"Bloodlines (Killer/Vampire)"
"Whose Doubler Is It Anyway? (Doubler/Killer)"
"Rolling Hills (Doubler/Killer)"

Have fun!
