Blind Leading the Blind

Blind Leading the Blind (also known as Blind Cube Crisis, Tiki Towers, Palanquin Slalom, Flip Out, Four on the Floor, Blind Build, Blind Rage, Money Roll, Seers and Doers, Smoko, Family Ties, Ow Pairs, Haulin' Oats, and Collar Blind) is a recurring Survivor challenge.

Rules
One castaway from each tribe would work as a caller, directing their blindfolded tribe mates in collecting items spread out in a field and returning them to their tribe's designated area. Once all of the items had been gathered, a second portion of the challenge (typically a puzzle) would occur. The first tribe to complete this portion of the challenge would win.

History
The challenge first appeared in  for reward in the form of Doritos and Mountain Dew. Jerri Manthey was the caller for Ogakor, while Nick Brown was the caller for Kucha. First, the blindfolded tribe members must place two logs between a sawhorse. Then, they must switch a pair of traps, one on the table, the other in the water. Next, the members must grab a bucket and fill it with water. Then, they must place the water in a larger bucket. When the large bucket overflows, the tribe members must then place the picnic basket on the table with barrel of Mountain Dew. The first tribe to do so would win. Kucha won, reestablishing their dominance.

In, the caller (Gabriel Cade for Rotu and Kathy Vavrick-O'Brien for Maraamu) would guide their blindfolded members to find 14 tiki pieces scattered around the field. Once they have all 14 tiki pieces, they will take off their blindfolds and assemble the tiki correctly. The first tribe to finish wins reward (a chance to raid the opposing tribe's camp). Maraamu won reward, allowing them to raid Rotu's camp.

In, Tanya Vance for Chuay Gahn and Penny Ramsey for Sook Jai acted as callers for their respective tribes, while the rest were blindfolded. The blindfolded tribe members carried the caller in a palanquin. Under the caller's commands, the tribes navigated a figure of eight course, both going in opposite directions. Along the way, the caller would untie several bags hanging from stations. The first tribe to come back would win a lantern and fishing supplies. In a close race, Sook Jai won the challenge.

In, Joanna Ward was Jaburu's caller, while Butch Lockley was the caller for Tambaqui. The callers must guide their blindfolded tribemates to 30 giant puzzle pieces. Once all 30 pieces have been collected, the tribe members must remove their blindfolds and complete the puzzle. Jaburu won the challenge and a jar of fishing bait as reward.

In, this challenge was seen in the background when Jenna Morasca quit on Day 9. When this challenge was finally played in the following episode, Jerri Manthey served as the caller for Saboga, Alicia Calaway was the caller for Chapera, and Richard Hatch was the caller for Mogo Mogo. The callers must guide their blindfolded tribemates to 15 puzzle pieces. Once all 15 pieces have been collected, they must remove their blindfolds and complete a cube puzzle. Saboga finished first, followed by Mogo Mogo, sending Chapera to Tribal Council.

In, the caller (Lea Masters for Lopevi and out Scout Cloud Lee for Yasur) must guide three groups (each tied together) to retrieve twelve pairs of puzzle pieces, then work to assemble three puzzles on a set of scaffolding. Lopevi assembled the puzzles and climbed the scaffolding first, winning immunity and flint. This challenge would be used again episodes later when the Final 7 had to direct their blindfolded loved ones to find bags of puzzle pieces through a course. Once the loved ones found all of the bags, the loved ones and castaways had to solve a puzzle. It came down to Ami Cusack and her girlfriend, and Chris Daugherty and his fiancée. Ami and her girlfriend completed the puzzle to win Ami immunity before Chris and his fiancée, and Chris sadly told her his fate in the game was sealed.

In, Brooke Struck for Nakúm and Gary Hogeboom for Yaxhá served as the callers for their tribes. The blindfolded castaways must collect materials needed to construct an archeological tent, while the callers must guide his/her tribemates (blindfolded and tethered in pairs). After collecting all pieces, the blindfolds can be removed and the tribe must assemble the tent. After assembling, the tribe must go back to their tribe mat. Yaxhá collected their pieces first, but quickly stumbled as they built their tent, giving way to Nakúm's win.

The challenge was used again in. Lisi Linares served as the caller for Ravu, while Michelle Yi served as the caller for Moto. The caller must guide one blindfolded member at a time down a field to smash one of five hanging skulls with a war club they're holding, grab the tiles that fall out, take them to the solving station, and run back. Once all five sets of tiles are on the station, the entire tribe runs down the field to it and arranges them to form a two-word phrase ("Cannibal Isles"). Moto won immunity, sending Ravu to Tribal Council.

In, the challenge was used as a Reward Challenge. Two callers for each tribe (Eliza Orlins and Kathy Sleckman for Airai and Cirie Fields and Tracy Hughes-Wolf for Malakal) would direct four blindfolded members who were pushing a large money stone through a forest course. Along the course, the money stone would crush four tiles that would reveal a pair of smaller money stones. Three tribe members would then use these eight stones to solve a rotating cog puzzle. Although the tribes were evenly matched throughout the course, Malakal pulled away during the puzzle making part of the challenge and won reward.

In , the challenge was used for reward for an umbrella, folding chairs, pillows, blankets, and a hammock. The tribes will form up into three pairs. The callers were Joe Dowdle for Jalapao and Debbie Beebe for Timbira. The caller must guide the blindfolded players though a maze to get three buckets. Once they reach a water tower, they must fill the bucket with water. Then, they must return to start and empty the water into a container, raising a flag. Then they must repeat the process with corn. Due to Timbira's struggling, Jalapao quickly took a lead and won easily.

In, James Clement served as the caller for the Heroes, while Jerri Manthey was the caller for the Villains. The callers must guide their blindfolded tribemates to 10 puzzle pieces. Once all 10 pieces have been collected, the entire tribe must work together to complete a cube puzzle. The Villains won immunity, sending the Heroes to Tribal Council.

In, Brenda Lowe served as the caller for La Flor, while Tyrone Davis was the caller for Espada. Using only verbal commands, the caller will direct their tribemates to collect 10 items scattered on the field. Once all 10 items have been collected, the caller will direct one pair out to find a set of keys, which will unlock a chest. The first tribe to get their chest and all ten items back to the start wins immunity and the reward. La Flor used the Medallion of Power, giving them a two-item head start and ultimately giving them the win.

In, the callers (Rob Mariano for Ometepe and Stephanie Valencia for Zapatera) would guide their tribemates though a maze to collect four bags filled with coffee beans and puzzle pieces. The callers must use the pieces to spell out a phrase. The first tribe to do so wins coffee, sweeteners, pastries, and immunity. Zapatera initially had the lead, but Ometepe was able to surge ahead and win.

In the tribes would be separated into pairs and dressed to resemble twins. One set of twins will be callers (Coach Wade and Rick Nelson for Upolu and John Cochran and Jim Rice for Savaii), while the other two sets of twins will collect bags of masks. Once all four bags are collected, one set of twins will empty the bags and, using only their sense of touch, will pair up the masks into matching pairs. The first tribe to get it right wins reward and immunity. Savaii fell behind after Cochran struggled untangling the ropes, giving Upolu immunity.

In, the callers (Sabrina Thompson for Salani and Bill Posley for Manono) would have to direct their paired up tribe mates to five stations. At the stations the castaways would have to pull a lever, releasing an overhead bucket of water and a bag of puzzle pieces. Once all the bags were collected, the caller would have to solve a puzzle. The first tribe to complete the puzzle would win the challenge. Salani won the challenge for immunity.

In, the challenge was used as a Reward Challenge. One member of each tribe (Tasha Fox for Luzon, Cliff Robinson for Aparri, and Alexis Maxwell for Solana) would act as a caller while two other blindfolded tribe members would navigate the course to retrieve five items and a flag, eventually working with a third blindfolded tribemate to hoist the items up to the caller's platform. Throughout the challenge, the Solana and Luzon tribes were neck-and-neck, while Aparri constantly trailed. However, after Solana won the challenge, J'Tia Taylor struggled with hoisting Luzon's flag, resulting in the Aparri tribe catching up and eventually placing second.

In, the challenge was reused in the same form as the Cagayan version as a Reward Challenge, with the callers being Carolyn Rivera for Masaya, Sierra Thomas for Escameca, and Joe Anglim for Nagarote. During the challenge, Escameca member Kelly Remington was hit by a falling platform. Despite the seemingly serious injury, Kelly continued to compete in the challenge. Kelly's injury contributed to Escameca's loss, allowing the Nagarote and Masaya tribes to win a reward of chickens.

In, the challenge appeared as an Immunity Challenge using the same design as All-Stars and Heroes vs. Villains. The caller for Bayon was Kimmi Kappenberg, Kass McQuillen was the caller for Ta Keo, and Jeff Varner was the caller for Angkor. After many injuries suffered by members of every tribe, Bayon finished their puzzle first, closely followed by Ta Keo, winning them both immunity.
