Tribe Names

The Names of the Game

Every tribe name comes from somewhere. Tagi and Pagong were beaches on a Bornean island; Nobag is just “Gabon” backwards; Enil Edam is a son’s tribute spelled in reverse. From real places to words in twenty languages to inside jokes scrawled on a buff — here’s where all of them came from.

Worth knowing

The best of the bunch

A few names carry a whole story — a backwards spelling, a private joke, a video-game reference snuck past the cameras.

Enil Edam

Caramoan merge tribe — 'Madeline' spelled backwards and split in two, named by Malcolm Freberg after his mother. The second backwards-spelling merge name, after Nobag.

S17 · Gabon

Lumuwaku

S39 · Island of the Idols

Chaboga Mogo

All-Stars merge tribe — a portmanteau of the three starting tribes Chapera, Saboga, and Mogo Mogo (CHA-bo-ga + MOGO). Chosen by Alicia and Amber; at five syllables it's one of the longest tribe names in the game.
