Brain Teaser IQTest: Can You Solve The Prisoner Hat Riddle?- Solution

If you are still trying to get the answer to this, we have the answer to this puzzle. This brain teaser is a great way to test your observation skills and how sharp you are. If you still haven’t gotten the answer, the picture given below will make you understand this solution better.

Super-intelligent alien overlords have captured you and nine other individuals. The aliens think humans look quite tasty, but their civilization forbids eating highly logical and cooperative beings. Unfortunately, they’re not sure whether you qualify, so they decide to give you all a test. Can you solve this hat riddle? Here we have solved it just take a look!

  • Let’s see what happens if the hats are distributed this way. The tallest hostage looks in front of him and sees three black hats; he says “black,” telling everyone else he sees an odd number of black hats. He misjudges the colour of his hat, but it’s okay because everyone is permitted to make one mistake.

  • Prisoner two also notices an abnormal proportion of black hats, so she recognises that hers is white and responds correctly. Indicating that this must be one of the black hats the first two convicts spotted, prisoner three notices an even number of black hats.

  • When prisoner four hears that, she understands that since one black hat was missing, she should search for an equal number of them back here.

  • However, she only notices one, leading her to assume that her hat is also black. The five through nine inmates are each searching for an odd number of black hats, which they find, so they deduce that their hats are white.

  • Everything now depends on you at the head of the queue. The unusual quantity of black hats the ninth prisoner noticed can only indicate one thing.

  • You’ll see that this tactic functions for any feasible hat configuration.

  • The probability that the first prisoner will incorrectly identify his hat is 50%, but thanks to the parity information he provides, everyone else can identify theirs with 100% accuracy.

  • Each starts off anticipating encountering something unusual or an even number of the designated colour caps. If the numbers they count don’t add up, they must own that particular hat colour.

  • And each time it does, the person in line behind them switches the parity they are expecting to see. So that’s all; you may now leave. These aliens appear to have to starve or find other less sensible organisms to kidnap
