Brainteasers are a great way to test your logical thinking and reasoning skills. They come in various forms, from riddles and logic puzzles to mathematical problems and visual challenges. Brainteasers often require you to think outside the box and consider alternative perspectives to arrive at a solution. One such interesting brainteaser challenges you to find the holes hidden in the T-shirt. At first, it might look easy, but those only with keen vision would be able to spot all the holes. The picture shows a torn T-shirt and the challenge is to spot the hidden holes in under nine seconds.
