Schrödinger's Dominoes

• S-Cells: Place the digits 0-9 once each in every row, column, and 3x3 box. To do this, there is a single 's-cell' in every row, column, and box that contains two digits. The given digits are not 's-cells.'
• S-Zeros: The value of every 0 in the grid is simultaneously 0 and 10.
• S-Dominoes: A grey diamond between cells indicates the presence of at least two DIFFERENT relationships between the values in those adjacent cells. There are four types of relationships: 1) The values are consecutive, 2) the values are in a 1 to 2 ratio, 3) the values sum to 5, or 4) the values sum to 10. Different values in a cell can be used to fulfill different relationships and not all values must be used.
• e.g. an 's-cell' containing 4 and 6 adjacent to a cell containing 5 would not qualify as an 's-domino,' but an 's-cell' with a 5 and a 6 adjacent to a cell with a 4 would.
