A fiendishly tricky optical illusion challenging people to find all of the triangles in the image is the latest puzzle driving the internet to distraction.

The drawing - which was shared on the website for US-based Optics4Kids - is a Kanizsa Triangle, and offers no clues as to how many of the shapes are present in the picture.

At first glance, the sketch seems to capture just two triangles - one facing up and another turned upside down.

However, the website's answer reads: 'There are no triangles. In reality there are only 3 V shapes and 3 shapes that look like Pac-Men.'

In the illusion, a white triangle can be seen in the image even though there is no such shape present.
