Sudoku: Fill every row, column and marked 3x3 box with the digits 1-9.

Rowena and Colin: Rowena the row indexer appears nine times in the grid, exactly once in each row, column and marked 3x3 box and has to be filled with a complete set of the digits 1-9. Colin the column indexer follows the same rules. A cell may not have both roles.
Within each marked 3x3 box Rowena and Colin pair up to index a cell. The digit in the indexed cell serves as multiplier for both Rowena and Colin.
Example: Let's say in one 3x3 box Rowena is a 4 and Colin a 2. The indexed cell for this pair then would be R4C2. Let's say the digit in R4C2 is a 5. The value of Rowena would then be 4x5 = 20 and the value of Colin would be 2x5 =10.
Note: There is no restriction on how often a digit may appear in indexed cells. A cell containing Rowena or Colin may also be an indexed cell. In this case the multiplier still is the digit in that cell.

Killer: In cages marked with a dashed line digits must not repeat and the values have to add up to the total given in the top left corner of a cage.

Memory Line: The sum of the values along the red line equals the sum of the digits in all nine indexed cells in the grid.

Have fun solving!
