Chained Killer Sudoku

(Published on 12. January 2020, 23:22 by Shinya)

Normal Sudoku rules apply. Every dotted cage may contain every number only once. The sums of digits in cages connected by a chain link differ by exactly 1. Neighbouring cages with sums different by 1 may or may not be connected by a chain link. If cells are connected by a "bigger than" symbol, the open side indicates the bigger number.

Solution code: Row 4, column 3

Exactly, the oval shapes looking like chain links.

Just for clarification's sake here, a 'chain link' is one of those white oval shapes?
