1% Visionaries: M-Flooded Puzzle Outsmarts London’s Quickest Eyes in 11 Seconds

London’s legendary ‘M Flood’ puzzle challenges 1% of sharp-eyed visionaries to spot a rogue N in 11 seconds, outwitting 99% of commuters and Google’s “How do I solve visual brainteasers fast?” crowd. Zahna Eklund and Liam Gilliver marvel, “If you nail it, you clearly have an ultra beady set of eyes.”
Drawing from the squiffy-eyed confusion, the test demands lightning reflexes and claims to improve attention span—mirroring trending searches like “Are visual puzzles good for your brain?” and “What is the hardest brainteaser?” Imagine a green sea of Ms, one N, and a ticking timer mocking your morning coffee.
Only 1% of quick-thinkers spot the rogue N among 100+ Ms in under 11 seconds—leaving the rest cross-eyed, their coffee cold, and their pride misplaced.
