Brain teasers provide a mental workout that engages your cognitive faculties, offering a productive alternative to mindless scrolling through negative online content. These challenges test your thinking, problem-solving skills, and creativity through puzzles, riddles, optical illusions, and lateral thinking exercises.

Optical illusion pictures often go viral on the internet, testing IQs and leaving viewers shocked. One mysterious image features black and white stripes designed to change patterns as you move the picture up, down, left, or right.

Another optical illusion reveals hidden images of two creatures, challenging observers to see either a cat or a moose against a background of black, white, and purple. Close scrutiny causes both creatures to disappear.

These viral brainteasers claim to assess lateralization of cognitive ability, suggesting that individuals may recognize specific images based on their brain's dominant side.
