The 1% Club: 30 Contestants Stumped by Tricky London Traffic Puzzle — Could You Spot the Mistake in 30 Seconds?
A seemingly ordinary scene of London traffic proved surprisingly difficult for contestants on The 1% Club, with 30 players caught out by a picture puzzle that required just one crucial detail to be spotted.
Hosted by Lee Mack, the popular ITV quiz challenges contestants to rely on logic, observation and common sense rather than general knowledge. But in this round, three images of familiar London streets were enough to leave players struggling to find the right answer before the 30-second countdown expired.
Can You Spot What’s Wrong With These Traffic Pictures?

Contestants were shown three side-by-side pictures featuring London traffic, including red double-decker buses, pedestrians and taxis. Their task was straightforward: identify which image contained a mistake.
As the players studied the pictures, Lee Mack joked: “I think it’s all of them… the traffic’s moving.”
However, once the 30 seconds were up, 11 contestants were revealed to have selected the wrong answer and were eliminated from the game.
The correct choice was picture A, which showed vehicles travelling on the wrong side of the road. Lee also revealed that 19 contestants had used their passes during the question.
With 11 incorrect answers and 19 passes, the challenge left a total of 30 players unable to progress without difficulty.
The 1% Club’s Track Record of Tricky Questions

The traffic puzzle was far from the first challenge to catch contestants off guard. Since its debut, The 1% Club has become known for questions that appear easy at first glance but demand careful observation and precise thinking.
In another episode, 23 contestants were eliminated by a 70% question involving two people writing the same sentence with different hands.
Lee asked players to consider the final word John would write if he used his right hand, then work out what Keith would write last if he used his left hand instead. The correct answer was “be” — because changing the hand used to write would not alter the sentence’s final word.
A separate 80% picture puzzle also proved challenging, leaving 13 contestants baffled. Players were shown three images featuring people dressed as a gorilla, a clown and a horse, and had to identify which picture differed from the others.
The key was in the orientation of the images: picture A was upright, picture B was upside down, and picture C was tilted to the right. The correct answer was B, because the positions of the gorilla and horse had been switched compared with the other two pictures.
Other Quiz Show Questions That Left Players Stumped
The 1% Club is not the only television quiz to challenge contestants with questions that seem simple until the clock starts ticking.
Who Wants to Be a Millionaire?
Earlier in the year, Who Wants to Be a Millionaire? viewers reacted strongly to a question they described as one of the show’s worst.
Host Jeremy Clarkson asked contestants to identify which letter had never begun the surname of a Best Actress Oscar winner at the ceremony from 2000 onwards. The options were G, K, M and W.
Contestant Glen had already secured £32,000 and had to make a guess. He chose G, which turned out to be correct. Best Actress winners since 2000 have included Nicole Kidman, Frances McDormand and Kate Winslet.
The 1% Club’s Birthday Brainteaser

Another question on Lee Mack’s show left both contestants and viewers puzzled.
Players were told that Edna’s birthday was on 6 April and Jen’s birthday was on 15 October, then asked to determine Amir’s birthday in January.
The clue relied on the positions of words in the question. The number 6 corresponded to the sixth word, while 15 matched the fifteenth word. Applying the same pattern revealed that Amir’s birthday was 24 January, corresponding to the 24th word.
The Chase
ITV’s daytime quiz The Chase also tested contestants with an unusual food-related question.
Players were asked what someone with a nightshade intolerance should avoid eating, with sweetcorn, potatoes and carrots as the options. Contestant Steve chose sweetcorn, but the correct answer was potatoes.

Could You Have Beaten the 30-Second Countdown?
The London traffic question demonstrated how easily a small visual detail can be overlooked under pressure. With three similar pictures to compare and only half a minute to decide, contestants had little time to reconsider their choices.
Would you have spotted the mistake that eliminated 11 players — or would you have used a pass like the other 19 contestants?
The 1% Club airs on ITV1 and is available to stream on ITVX.
