Who is in the cast of Squid Game season 2?

New cast members in season 2

  • Yim Si-wan joins as Lee Myung-gi, Player 333 (ELLE (lifestyle magazine))
  • Kang Ha-neul plays Dae-ho, Player 388 (ELLE)
  • Lee Jin-wook appears as a yet-unnamed player (Wikipedia (cast database))
  • Park Gyu-young portrays Kang No-eul, Guard 011 (Wikipedia)
  • Choi Seung-hyun (T.O.P.) plays Thanos, Player 230 (ELLE)
  • Yang Dong-geun is Park Yong-sik, Player 007 (Wikipedia)
  • Jo Yu-ri appears as a new contestant (Wikipedia)

Returning cast members

  • Lee Jung-jae reprises his role as Seong Gi-hun (Player 456) (ELLE)
  • Lee Byung-hun returns as the Front Man (ELLE)
  • Wi Ha-jun returns as detective Hwang Jun-ho (Wikipedia)
  • Gong Yoo makes a reappearance as The Salesman (ELLE)
Bottom line: Season 2 nearly doubles the main ensemble while keeping three core characters from season 1. For returning viewers, the familiar faces of Gi-hun and the Front Man anchor a fresh set of players.
The upshot

The casting strategy for season 2 balances continuity with reinvention. By retaining the three most plot-critical characters — Gi-hun, the Front Man, and Jun-ho — the show keeps its emotional core while introducing a dozen new actors who expand the world.

Who is in the cast of Squid Game season 1?

Main cast of season 1

Nine principal actors formed the original ensemble that propelled the series to global fame.

  • Lee Jung-jae as Seong Gi-hun (Player 456) (MyDramaList (fan database))
  • Park Hae-soo as Cho Sang-woo (Player 218) (MyDramaList)
  • HoYeon Jung as Kang Sae-byeok (Player 067) (MyDramaList)
  • Oh Young-soo as Oh Il-nam (Player 001) (Rotten Tomatoes (review aggregator))
  • Heo Sung-tae as Jang Deok-su (Player 101) (AsianWiki (community wiki))
  • Anupam Tripathi as Abdul Ali (Player 199) (Wikipedia (cast database))
  • Kim Joo-ryoung as Han Mi-nyeo (Player 212) (Wikipedia)
  • Lee Yoo-mi as Ji-yeong (Player 240) (Wikipedia)
  • Wi Ha-joon as Hwang Jun-ho (Wikipedia)

Supporting cast

Beyond the main nine, several actors left a mark in smaller but memorable roles.

  • Lee Byung-hun as Front Man (appears in the final episodes) (ELLE (lifestyle magazine))
  • Lee Seo-hwan as Park Jung-bae (Player 390) (Wikipedia)
  • Kim Si-eun as Gi-hun’s daughter (AsianWiki)

The implication: Season 1’s cast was deliberately lean — nine main players plus a handful of supporting characters — which made each death land harder and kept the narrative focused.

Is Kai Cenat in the cast of Squid Game?

Kai Cenat cameo rumor

Online chatter has suggested that popular streamer Kai Cenat appears in season 2. No official cast list includes his name, and the rumor appears to originate from social media memes (Netflix Tudum (official hub)). Netflix has not announced any such casting.

Evidence and denial

Neither Netflix nor any credible entertainment outlet has reported a Cenat cameo. The streamer himself has not confirmed involvement.

What to watch

This rumor is a classic internet echo chamber: it started as a joke, gained traction on TikTok, and now appears in search results as if it were fact. No evidence supports it.

Who will be in the cast of Squid Game season 3?

Confirmed cast for season 3

Netflix confirmed that Lee Jung-jae and Lee Byung-hun will return for season 3 (Netflix Tudum (official hub)). Other details remain unconfirmed.

Expected returning actors

Wi Ha-jun is widely expected to return based on season 2’s cliffhanger, but no official announcement has been made.

The trade-off: With season 3 filming reportedly underway, fans have to wait for official casting announcements. The only certainty is the two leads — everyone else is speculation.

Who plays the main character in Squid Game?

Actor behind Seong Gi-hun

Lee Jung-jae portrays Seong Gi-hun (Player 456), the central protagonist who wins the season 1 games and returns in season 2 (MyDramaList (fan database)). His performance earned him an Emmy Award for Outstanding Lead Actor in a Drama Series.

Character background

Gi-hun begins as a debt-ridden gambler who risks everything for the prize money. By the end of season 1, he is transformed — and season 2 shows him as a man driven by revenge and guilt.

Why this matters: Lee Jung-jae’s casting was a gamble — he was primarily known for romantic thrillers, not action — but his range made the character’s arc believable and emotionally resonant.

Comparison: Season 1 vs Season 2 Main Cast

Seven actors cross over between seasons, while the rest are new additions. Here’s how the lineup changed.

Actor Season 1 Role Season 2 Role
Lee Jung-jae Seong Gi-hun (Player 456) Seong Gi-hun (Player 456)
Lee Byung-hun Front Man Front Man
Wi Ha-joon Hwang Jun-ho Hwang Jun-ho
Gong Yoo The Salesman (cameo) The Salesman
Yim Si-wan — Lee Myung-gi (Player 333)
Kang Ha-neul — Dae-ho (Player 388)
Park Gyu-young — Kang No-eul (Guard 011)

The pattern: Season 2 retains the three most crucial characters from a plot perspective — the protagonist, the antagonist, and the detective — while injecting fresh faces to create new alliances and conflicts.

Confirmed facts and what’s unclear

  • Main cast for season 1 (list from Wikipedia (cast database))
  • Season 2 cast from Netflix Tudum (Netflix Tudum (official hub))

What’s unclear

  • Exact cast for season 3 beyond lead actors
  • Kai Cenat involvement in any capacity
  • Whether original actors appear on Squid Game: The Challenge

“Lee Jung-jae returns as Seong Gi-hun, a changed man.”

— Netflix Tudum (2024)

“Season 2 introduces a new set of players with unique backstories.”

— ELLE Magazine (2024)

For Netflix, the casting strategy is clear: retain the proven draws while injecting enough new talent to keep the series fresh. For viewers, the question is whether the new characters can match the emotional impact of season 1’s tragic ensemble. The answer will arrive when season 2 streams in December 2024.
