Optical illusions and brain teasers are a fun way to challenge our minds. This one features dolphins — at first, it seems like just a few dolphins in the sea, but hidden within the image are 17!

Here’s the breakdown:

First row: 5 dolphins
Second row: 6 dolphins
Third row: 6 dolphins

Some dolphins are camouflaged or blend into the scene, making it tricky to spot them all.

Next, try spotting 16 hidden tigers in a jungle scene. Some are disguised within the foliage or other animals.

For a math challenge, count the squares in an image. If you found 40, you’re correct!

Brain teasers like these help improve focus, pattern recognition, and give our brains a fun workout. How many did you find? Challenge your friends to spot them all!
