Trials

Trials (commonly seen with the name of the season before it) is a recurring challenge that first appeard in Survivor: Laos as the final reward/immunity challenge, and has since appeared as an immuntiy challenge.

Former
As making it's debut in Laos, the challenge was divided into three parts, each representing a different skill; luck, math, and words. After each section, the person who was last would be eliminated from the challenge, no longer competing for reward/immunity. This pattern would continue until the third and final part, where whoever placed first won reward and immunity.

Current
"Trials" had a renovation when it returned in Cuba, following a different format. Like Laos, the Final 3/4 compete in a series of challenges, ranging anywhere from 2-6 challenges. Each one was a point value, with the more difficult tasks having higher point values, and vice versa. The contestant to collect the highest amount of points after all are completed is granted immunity, and guaranteed a spot in the Final 2/3.
