Lock, Load and Light is a recurring challenge of Survivor.
The tribes must run up and over two sand mounds, assemble a puzzle boat, using unique braces to hold it together, row out to a cauldron, light a torch, row back, remove the braces, and take them to the starting line. Two players will use 16 puzzle pieces to assemble blocks representing compass directions, then the tribe fits the blocks and braces into a climbing wall and climbs up to light a fire bale. The first tribe to do so would win.
In Survivor: Cook Islands, the challenge was used as the first Immunity Challenge of the season. In addition to immunity, the first three tribes to finish the challenge would win flint as a reward. The first-placing tribe would also win a crate full of fire making essentials. Puka Puka finished in first, winning the fire-making tools and immunity. Aitutaki and Rarotonga finished in second and third respectively, sending Manihiki to Tribal Council.
In Survivor: Heroes vs. Villains, the challenge was once again used as the opening Immunity Challenge. Despite the Heroes taking the lead in the rowing portion of the challenge, the Heroes, especially Sugar Kiper, struggled with the puzzle. This allowed the Villains take the lead and win the challenge.
