Brain teasers are more than just casual entertainment. These puzzles offer you a mental workout while you spend your leisure time.
Moreover, these puzzles are backed by science and researchers. According to Intra Care, “Most brain games work on the principle of “Here’s a problem. Let’s solve it.” The solution comes usually after analyzing the problem from multiple angles. Solving a problem requires your brain to use a combination of visualization, reasoning, memory recall, and concentration.
“All good brainteasers you engage with give you a chance to practice these skills, with numerous benefits for both physical and mental health,” it adds.
In today’s challenge, you will be looking at a very pretty wedding scene that is filled with the couple and a few guests. Everyone appears normal at first glance. But one person in the image is not human.
Your task is simple but demanding, which is to find who among them is an alien in just 19 seconds.
This puzzle tests how quickly your brain can filter visual noise and identify subtle irregularities. The faster you detect the odd detail, the stronger your visual discrimination and focus under time pressure.
Try it now. Start your timer.

Wedding scenes are visually crowded and everything looks very concealed.
Your brain naturally groups faces, outfits, and expressions into familiar patterns. The alien is taking the exact advantage and blends into this normalcy, forcing you to question assumptions instead of scanning randomly.

Tick tock. The clock is running.
3… 2… 1…
Time’s up.
Did you spot the hidden alien? If you spotted it within 19 seconds, it shows that you tried to reset your brain’s automatic functioning.
If you missed it, that’s completely normal. Brain teasers are designed to expose how easily the mind fills gaps with assumptions. The good news is that repeated exposure improves detection speed over time.
