Normal Sudoku rules apply. Clues above or below the grid give the sum of all digits along the indicated diagonal, which may repeat. Clues left of the grid give the sum of digits between the 1 and 9 in that row.

Each line with the same color contains the same sequence of numbers; the sequence loops and each line may start and end at any point in the sequence.

For example, if a purple line has the digits 2855 in that order, each other purple line is one of 2855, 8552, 5528, 5285, or one of 5582, 5825, 8255, 2558.
