Sudoku Ripeto. A variant of Sudoku with repeated symbols

What is it about?

Sudoku Ripeto is the first Sudoku variant to admit any combination of repeated symbols. We present other Sudoku Ripeto families, each with a different repetition pattern. We define Sudoku Ripeto squares and puzzles, prove several solving rules that generalize those for Sudoku, and give sufficient conditions to flexibly solve puzzles with rules only, without search.

Why is it important?

Sudoku Ripeto is a natural generalization of Sudoku.
