White cells have exactly one orthogonally connected cell with a consecutive digit.

There are two other types of cells: Cells with no consecutive orthogonal neighbour, and cells with more than one consecutive orthogonal neighbour. Green cells are of one type, and blue cells are of the other.

Cages contain the same four digits, and digits cannot repeat within a cage.

Normal Sudoku rules apply.
