Tazza 1 and Female Tazza follow a gambling main character.
Female Tazza is more of an investigation, whereas Tazza 1 is more packed with action.

Both titles are centered around gambling.
Both main characters infiltrate a gambling house in order to get revenge.
Tazza uses Hwatu (Korean card game), whereas Female Tazza uses both Hwatu cards and poker cards, so the latter might be easier to follow.

Both movies revolve around the themes of gambling and revenge.
Female Tazza mixes the Korean traditional gambling game and poker games, so it might be easier to understand.

These mini-series are both short format classic horror stories.
They tell a new tale each episode and are supposed to be a "story within a story", meaning the protagonist is being told or shown the tale.
I found they overall had a similar vibe.
