Is the whole Yu Gi Oh (Classic) series on Netflix?

You should know what I mean, for example with HunterXHunter 3 seasons. This does not correspond to the whole 3 seasons)

I see 5 seasons. According to Wikipedia there are 6. So unfortunately you don't get the complete series.

It's seasons 1-5 on it. So actually. Only the "0." is missing Season that does not play a major role in terms of content. In addition, they do not play the classic card game there and sometimes see it differently. So yes, the classic yugioh series is completely on Netflix.
