Normal Sudoku Rules Apply.

Column Index
The digits in Column 1 give the Column position of Digit '1' in the respective Row. For example, if R1C1 was '7', then the '1' would be in R1C7.

Sandwich Sums
The numbers outside the grid give the total of the digits between 1 and 9 in that Row.

Killer Cages
The digits in a killer cage sum to the total in the top left corner; digits may not repeat within each cage.

Digits may not repeat along the Blue Diagonal.
