Standing in a circle for thirty-eight minutes, oddly gripping
A classic endurance game where 100 contestants stay inside red circles.

Jimmy Donaldson places 100 contestants inside painted ground circles to compete for $500,000 in an endurance experiment. The opening visual presents 100 distinct circles across a massive venue, establishing the arena scale immediately (which makes tracking contestants very engaging for kids). Competitors manage sleep, meals, and mini-challenges without stepping outside their circle lines. The long experiment is edited into lively milestone updates.
