The social ancestor of the duplicate game: hands are dealt and played once, with no board and no comparison; Scoring runs across a rubber rather than per deal, so the Laws of Duplicate Bridge do not apply in full
Why people argue about this
People often assume that since Rubber Bridge is a precursor to Duplicate Bridge, it should follow all of its rules, leading to misunderstandings about how scoring works in Rubber Bridge, which operates differently by running across an entire rubber (series) rather than per deal as in full Duplicate.
