Sixteen servants were split into two groups, odds and evens, and were summoned to Atua's mansion to compete in Atua's various challenges. In each round, one of the two groups will compete in a main challenge. The winner of that challenge earns immunity. The servant who placed last will be automatically sent to the arena, a place where two servants fight to remain in the game. The servants in the same group must then vote for one of their own to face the last place servant in the arena. The winner of the arena challenge stays in the game while the loser is eliminated from Atua's Challenge. This continues until there are eight servants remaining. The remaining servants will then compete in a Final Challenge, one that very long and very tedious. The servant who finishes first out of their group wins!
