Clone or Renban Sudoku (1112)
Instruction:
Apply classic sudoku rules. Each shape in the grid appears four times. Two shapes are clones, and digits in the same place in each shape must be identical. Other two shapes are renban groups, and they must contain a set of distinct, consecutive digits in any order. Cloned shapes may or may not be renban groups at the same time, and digits in it may repeat.
Identifying which shapes are clones and which are renban groups is part of the solving.
