Do or Die

How it works

A new-era gamble: the first castaway to drop out of the immunity challenge must pick one of three boxes at Tribal. Find the safe one and you're immune; choose wrong and you're sent home on the spot — no vote required.

Why it's iconic

Run twice and then shelved: Deshawn Radden drew the safe box at the Survivor 41 final seven, and it returned for one more turn in Survivor 42 before a near-unanimous fan backlash retired it for good.

The moment

Both times the player forced into it survived — and Jeff even removes one wrong box before the pick, making it a Monty Hall problem played out live at Tribal.
