The Bermuda Triangle, Amelia Earhart, and the Voynich Manuscript — history's greatest unsolved puzzles.
From vanished explorers to ancient codes that still defy decryption, history is full of puzzles that continue to captivate researchers and armchair detectives alike. This quiz covers 50 questions spanning famous disappearances, enigmatic ancient constructions, unsolved ciphers, lost treasures, and unexplained phenomena — all grounded in the best available evidence and leading scientific theories rather than pseudoscience.
You'll answer 50 randomized multiple-choice questions with instant feedback after each answer. At the end, you'll receive a shareable score card to compare with friends.
Questions cover the disappearance of Amelia Earhart, the Roanoke Colony's "CROATOAN" message, the Bermuda Triangle's statistical debunking, the Voynich Manuscript, the Wow! Signal of 1977, the Dyatlov Pass incident, the Zodiac Killer ciphers, Stonehenge, the Nazca Lines, the Antikythera mechanism, the lost Amber Room, and dozens more. You'll discover that many so-called mysteries have plausible scientific explanations backed by modern research.
Amelia Earhart disappeared on July 2, 1937, during her attempt to circumnavigate the globe near Howland Island in the central Pacific. The most widely accepted theory is that her Lockheed Electra ran out of fuel and crashed into the ocean. An alternative hypothesis suggests she landed on Nikumaroro (Gardner Island), where skeletal remains and artifacts consistent with a 1930s castaway were found, though DNA confirmation remains inconclusive.
Statistical analyses by the US Coast Guard and Lloyd's of London have shown that the Bermuda Triangle does not have a significantly higher rate of disappearances than any other comparable region of ocean with heavy traffic. The area between Miami, Bermuda, and Puerto Rico sees enormous volumes of shipping and air travel, and the number of incidents is proportional to that traffic. Many famous cases were exaggerated or inaccurately reported.
Some of history's most enduring unsolved mysteries include the identity of Jack the Ripper, the purpose of Stonehenge, the disappearance of the Roanoke Colony, the meaning of the Voynich Manuscript, the fate of the Amber Room looted by Nazis in 1941, and the construction methods behind the Egyptian pyramids and Sacsayhuamán's precisely fitted stones. While modern science has provided plausible theories for many of these, definitive proof remains elusive.
