How quickly can you spot the 20p in this annoying puzzle?

A barman from Wales set his mates a challenge that has gone viral, even though it’s just a simple case of observation. Mathew James Beach uploaded a photo of a tray of coins to Facebook, with the instruction to “find the 20p. The challenge has been getting on people’s nerves, with some having to sneak a peak at the solution after giving up in despair.

This is Mathew’s photo.

Here are some of the comments made by people who’ve given it a go.

That’s right – Mathew didn’t even put the 20p on the tray, he put it nearby, under a glass.

What a sneaky ba …rman.
