Overview
- The All Stars season launched on Tuesday, August 25 with 18 returning contestants drawn from nine seasons who begin the game in nine mixed‑gender duos created by production.
- Producers deliberately cast one man and one woman from each represented season to ensure parity and to assemble recognizable personalities with varied life stories and public profiles.
- The opening mechanic called 'destins liés' links each pair from the first episode to change how early voting and alliances form, because votes against one player now affect their partner.
- Contestants and producers say this edition increases difficulty with tougher, new challenges and harsher survival conditions, and production confirmed only one invited former contestant declined for professional reasons.
- Koh‑Lanta’s All Stars builds on the show’s 25‑year legacy by foregrounding veteran arcs such as career changes, parenthood, and influencer work, a choice meant to fuel early‑season drama and viewer interest.
