Tazza: The Song of Beelzebub
🎬 Film Overview
Jang Tae-young (Byun Yo-han) thinks he has the world in his hands. His online casino business is thriving, and his oldest friend, Park Tae-young (Roh Jae-won), who happens to share his name, helped him build it. Then Park takes everything from him, and according to Korean press coverage, the betrayal grows out of jealousy as Jang gets more of the spotlight. At rock bottom, Jang meets the legendary gambler Kwak Dong-wook (Jo Woo-jin), who teaches him poker. Years later the two Tae-youngs sit down again at a high-stakes international table, with revenge on the line. This is the fourth and final film in the Tazza series that began in 2006, and it trades hwatu for poker while the action moves from Korea to Japan and Vietnam. Press materials stress that it stands alone, so you do not need to catch up on the earlier films first.

✍️ KDramaWorlds Editor’s Take
Our honest opinion — and the kind of viewer who’ll love it most.
Giving both leads the same first name is a neat piece of setup. The film’s hook is that Jang Tae-young and Park Tae-young start as two halves of one business and end up as opposite sides of one table, and the shared name makes the betrayal feel personal before a single card is dealt. Viewers who enjoyed the cons and reversals in Payback: Money and Power will recognize the appetite for money and the ruin it brings.
Switching from hwatu to poker is the biggest change for a series known for card-slapping close-ups, and Jo Woo-jin as the mentor who teaches Jang the game gives the middle of the story its backbone. Korean outlets also note how far the film travels, from Korea to Japan and Vietnam, which fits a tale of an online casino empire. If the swindler-versus-swindler energy of The Player 2: Master of Swindlers appeals to you, this is a harder-edged cousin.
We are holding back a verdict for now. How the final game plays out is still being confirmed across Korean coverage, and we only publish the story and ending sections once they hold up across several reliable sources. For now, treat this page as the setup, the cast and the case for watching.
