Sudoku is Schrodinger's Killer by Starwarigami, App variant is KILLER


Place the digits 0-9 in the grid so that every row, column and 3x3 box contains every digit exactly once. To enable this, there is a single Schrödinger cell in each box, containing a superposition of two different digits. Every Schrödinger cell contains a unique pair of digits. No Schrödinger cell can see another Schrödinger cell by a Queen's move in chess (i.e. any distance horizontally, vertically or diagonally). Digits in a cage may not repeat and must sum to the indicated total. Schrödinger cells contribute the average of their two digits to the cage total.
