Schrödinger's Leopard
(Published on 12. July 2022, 11:52 by tesseralis)
Place the digits 0-9 exactly once in each row, column, and 3x3 box. To accommodate this, one cell in each row, column, and box is a Schrödinger cell that contains two digits.
Digits joined by a black dot have a ratio of 1:2. Schrödinger cells are treated as the sum of their digits. All possible black dots are given.
Solve on CtC.
Solution code: All Shcrödinger cells from top to bottom with the lower digit first.

Very nice puzzle ! I was so excited to do a Schrodinger puzzle that I overlooked the negative constraint the first time I read the rules, which lead to a dead end and a very long stare at the grid around midsolve... Solved very nicely when I finally realized my mistake. Loved the combination of S-cells and 1:2 ratio. Thanks.

@Christounet yeah, the negative constraint'll get you if you're not careful!
Fun fact: a regular black kropki puzzle cannot be unique, but the Schrödinger cell constraint makes it possible! -tess

This was my first time dealing with Schrödinger cells, WOW!.. it took me some tries, but finally I got it !.. Thank you so much for this challenge @tesseralis, please keep on setting!..
