How it works
Catch balls as they spit out of a spiraling metal track and feed them back in — with one hand tied behind your back — as more balls are added over time. Drop one and you're eliminated.
Why it's iconic
A maddening concentration test that's returned again and again, from South Pacific to Winners at War.
The moment
One of the most reused hand-eye tests of the modern game — it's decided immunities from Tocantins all the way to Survivor 50.

Blind Leading the Blind
Reward or immunity
One sighted caller per tribe stands on a platform and shouts directions to blindfolded teammates, steering them around a maze-like course to collect scattered pieces — then the whole tribe solves a puzzle.
Stacked Up
Reward or immunityDebuted Season 32
Standing on a wobbling balance beam, use a long-handled fork to ferry stacks of balls across and set them on a series of stands. Topple the stack and you start over; finish first to win.
A Bit Tipsy
Reward or immunityDebuted Season 27
Hold a rope to keep an unstable, tilting table level while you stack a tower of blocks on top of it. One wrong shift and the whole thing comes down — rebuild and keep going. First to top out wins.
