Brain teasers and optical illusions are often seen as just a source of entertainment, but experts say they are much more than fun. Regularly solving such puzzles not only sharpens problem-solving skills
but also boosts concentration, memory and overall brain health. Research even suggests that these challenges bring a sense of happiness and satisfaction, helping us stay mentally active and positive.
In this context, a new puzzle has gone viral on TikTok, posted by the account @quiz.n.riddle. The challenge asks users to spot the word ‘USA’ cleverly hidden among several ‘U5A’ within just 7 to 10 seconds.
At first glance, the puzzle looks easy, but many are struggling to find the hidden word. If you manage to spot it quickly, you can safely consider yourself both sharp-eyed and quick-witted.
If you’re still searching, here’s a small hint, the word is tucked away on the left side, near the bottom. The trick lies in how similar ‘U5A’ appears to ‘USA’, making it difficult for the brain to differentiate. Our mind often relies on past patterns and guesses, and this natural delay is what makes such illusions challenging.
For those who couldn’t find it, the answer is revealed in the circled section of the picture, it is the fourth word in the second row from the bottom.
The puzzle may be tough, but it serves as a reminder that sometimes, our assumptions make us miss what is right before our eyes. While some users took hours to solve it, others gave up altogether. If you spotted it in time, congratulations, both your mind and your eyesight are razor sharp. If not, don’t worry, keep practising, and soon you’ll be able to crack such brain teasers with ease.
