Another puzzle I made a while ago for the amazing puzzle pack Quads on Parade (free to download).
Rules:
Sudoku: Place the digits 1-9 exactly once in each row, column and box.
Quadruples: Digits in a Quadruple circle must be placed at least once in the four cells touching that circle.
Clones: Rings of the same colour are clones of each other, i.e., they include the same digits in the same relative positions.
Solution code: row 5

The back and forth between the quads and clones is really nice.
