The app pits players from all over the world in a battle of challenges and strategy to be the last one standing.
In seasons featuring more than two tribes, immunity will be available for all but the last place finishers, forcing this one tribe to Tribal Council.
The castaway who receives the Cursed Pearl gets one vote in the following Tribal Council.
In addition, the first-place winner of the duel must give a clue to a hidden immunity idol to any castaway in the main game.
