Brainteasers are puzzles, problems, or questions that are designed to stimulate cognitive processes such as critical thinking, problem-solving, and lateral thinking. They often require creative and unconventional approaches to arrive at the correct solution. Brainteasers come in various forms, including riddles, logic puzzles, maths problems, and word games.

These puzzles can be a fun way to challenge and entertain the mind, and they are often used in educational settings or as recreational activities. They may vary in difficulty, ranging from simple puzzles that can be solved quickly to more complex ones that may require deeper thought and analysis.

Examples of brainteasers include riddles that involve wordplay, logic puzzles where you need to work out the correct answer using a set of rules, and mathematical problems that require innovative approaches. The goal of a brainteaser is to engage your brain in a unique and stimulating way, encouraging you to think outside the box.
