Rules

Schrödinger Sudoku: Place the digits 0-9 once each in every row, column, and box. To fit all digits, each row, column, and box must have one Schrödinger cell, which contains 2 of the digits. The value of a Schrödinger cell is the sum of digits.

Region Sum Line: Values along the blue line sum to the same total in each 3x3 box the line passes through. If a line passes through a region multiple times, each individual segment sums separately.

Min/Max Cells: For each line, exactly one cell is a Min cell, and exactly one cell is a Max cell. The Min cell value must be strictly less than all of its orthogonally adjacent cells, and the Max cell value must be strictly greater than all of its orthogonally adjacent cells. The rest of the cells on the line cannot be Min/Max cells.
