We’re currently attempting a Guinness World Records™ title ourselves, so we understand the irony of writing about the biggest fails. Frankly, it frightens us to even say the word. But with our own attempt under way, we couldn’t help but wonder what happens when things don’t quite go to plan, so we’ve researched and collated a list of 10 of the most notable fails for your entertainment — from a dinosaur-costume crowd that was too big to count to a gathering of Kyles that fell 1,600 short. Ouch.

Of course, we'd much rather be celebrating a record-breaking success than featuring in a list like this ourselves. So please go play our Guinness World Records™ attempt Higher or Lower game so our manager can sleep. Do it for prizes. Do it for bragging rights. Do it to be part of a record.

Here's our list of top 10 fails.

1. The twins who were too many to count (Sri Lanka, 2020)  

Organizers in Colombo registered just over 6,000 pairs of twins in five hours, against a record of 3,961 pairs set in Taiwan in 1999. The crowd was so big that long queues for birth-certificate checks formed, many people left before registering, and the group could not meet Guinness's registration guidelines.

Spokeswoman Wasana Ranasinghe said: "We had more than we expected." Organizers said the turnout had probably been unable to meet the guidelines, and Guinness had not confirmed a result when the story was reported.

2. The dinosaur crowd that Guinness could not count (Drumheller, Canada, 2024) 

At Alberta's Jurassic Jamboree, an adjudicator recorded 3,000 people in dinosaur costumes using numbered wristbands, close to double the organizers' expectations. Guinness ruled the count inaccurate because people were seen leaving after being wrist banded, and the rules required everyone to stay in the area together for one full minute.

Marketing manager Keri Looijen said: "We weren't entirely prepared for that many people to come." 

3. The 1,500-metre sandwich that was eaten before it was measured (Tehran, 2008) 

A park in Tehran hosted an attempt at the world's longest sandwich, planned at 1,500 metres with 700kg of ostrich meat and 700kg of chicken. While three Guinness representatives were measuring it, the crowd rushed forward and ate it. It was gone within minutes, and the attempt failed to register.

4. The 5,441 scarecrows that were in the wrong place (Hoschton, USA, 2008) 

The Georgia city announced its bid in May and had until 1 September to gather scarecrows scattered across its neighbourhoods and roads. It finished with 5,441, beating the 3,311 set in Cincinnati in 2003 by more than 2,000. About 11 weeks after the city submitted its evidence, Guinness denied the record because of location.

Hoschton had listed its whole 30548 ZIP code as the site, while Cincinnati's scarecrows were displayed in one place. City Clerk Kristen Smith said Guinness wanted a single site: "It would need to be a field or a farm or one plot of land." Coordinator Robbie Bettis said the city was "kind of thinking about asking for an appeal", and a celebration bonfire was planned at Kenerly Farm for 3 January.

5. The 63,000-coaster tower that fell to a child (Cologne, Germany, 2026) 

German artist Benjamin Klapper, 49, who runs the media company MuVi 3D, built a tower of 63,000 beer coasters titled "Inside" in the Rhein-Center shopping mall in Cologne. He has said it took about 120 hours, though reports also describe more than a month of assembly.

Shortly before completion, the tower partially collapsed under its own weight. Klapper then invited visitors to take turns removing coasters until it fell, and a girl, the daughter of one of his helpers, won by pulling out a horizontal coaster on her first try.

Video of the collapse went viral, and some viewers questioned whether it was legitimate, however we now know the record was already failed before the girl collapsed the tower. Because of the structural failure, the attempt never qualified, and the record stays with Sven Goebel's 9ft 6in tower of 70,000 coasters from 2004. 

6. The Kyles who kept falling short (Texas, USA, 2024) 

Kyle, Texas used its annual Kyle Fair to chase the record for the largest same-name gathering. In 2023, city officials counted 1,490 Kyles, the largest turnout since the city began pursuing the record. In 2024, only 706 came, less than half the year before, and the town failed for the fifth consecutive year.

The target is the 2,325 people named Ivan who gathered on 30 July 2017 in Kupreski Kosci, Bosnia and Herzegovina, so the 2024 crowd was 1,619 short. One resident told KVUE: "It was really funny because when you're in a crowd and somebody yells 'Kyle', like 15 people all turn around." 

7. The ugly Christmas sweaters that did not add up (Detroit, USA, 2017) 

On Saturday 9 December 2017, people in ugly Christmas sweaters packed Beacon Park in Detroit in a bid to beat the record of 3,473. About 1,500 turned up, less than half the number needed and nearly 2,000 short. 

There was music, hot drinks and a silent disco, where dancers wore headphones and the music is not played aloud, but the crowd never got close to the total. 

8. The water balloon fight that fizzled (Bakersfield, USA, 2010) 

On the evening of 28 August 2010, Bakersfield High School tried to hold the largest water balloon fight to raise money for its music programme. Brigham Young University had set the record of 3,902 participants that July, and band director Randy Bennett set a goal of 5,000. Participants paid a $5 donation and received a Chick-fil-A coupon and a T-shirt.

Only 2,332 came, about 1,570 short, so BYU kept the title. Project coordinator Mary Osburn was still satisfied with the turnout, and Bennett had promised: "There is more fun than you can shake a stick at!" 

9. The sea of high-vis that stopped short (Wagga Wagga, Australia, 2018) 

In October 2018, Wagga Wagga in New South Wales tried to gather the most people wearing high-visibility clothing in one place, a title held by Japan, to promote World Mental Health Day. The target was 2,136. Despite last-minute calls for more people to join, 1,242 officially took part. 

Mental Health Australia chief executive Frank Quinlan said the day still "succeeded in raising community awareness". Organisers joked that participants could stand on one leg to set a new record, and a young attendee suggested a conga line of high-vis wearers. 

10. The 100-year-old marathon runner without a birth certificate (Toronto, 2011) 

Fauja Singh completed a marathon in Toronto in 2011 at the age of 100, but Guinness declined to ratify the record because it could not verify his age. Guinness requires a birth certificate, and he did not have one. He showed a British passport giving a birth date of 1 April 1911 and a letter from the Queen, which Guinness said were "not considered sufficient proof of age".

A letter from Indian government officials saying no birth records were kept there in 1911, and a statement from a former neighbour, were also rejected as insufficient. 

Methodology 

The list is an editorial ranking, not a data-driven one. Casinos.com compiled it through desk research in November 2026, searching news archives and trade coverage for Guinness World Records attempts that fell short or were rejected. An entry was kept only if it met all four tests: 

• A Guinness World Records attempt. The event was explicitly an attempt at, or application for, a Guinness World Records title. 

• Fell short or rejected. Reporting confirms it missed the target, was ruled invalid, or was declined, whether on turnout, verification or a rule. 

• Documented. At least one named news or official source was opened and read, not relied on from search snippets, and dates, numbers and quotes are taken from it. 

• Low harm. Attempts involving death or serious injury were excluded. 

The 10 were ranked by editorial judgement on three factors: the scale of the effort, the size of the gap between ambition and result, and how avoidable the failure was.
