Can you spot the hidden items in these pictures?

Looking for another brain teaser? See if your eyesight is up to par with this test.

The tricky quiz, developed by Casumo.com, challenges people to spot hidden items in four pictures. Players will have 45 seconds to find the special object on each picture before moving on to the next.

“Most people get at least two out of the four, but it’s rare to get them all!” said the website’s spokesperson Richard Gargan.
