Can you spot the Santa with a sack full of cash?

With the Christmas season well and truly upon us, there's no end of festive puzzles sweeping the web.

However the latest eye-boggling brainteaser to leave the internet scratching their heads may just be the trickiest yet.

The Where's Wally-style quiz challenges users to spot the Father Christmas carrying a sack bursting with cash among a sea of Santas.

With over 160 to choose from, the figures are almost identical with matching hats and brown bags - except for their coats being different shades of red.

To make matters even more complicated, each bearded Santa is holding a sack overflowing with green presents - the exact same colour as the wad of cash.

However, eagle-eyed users have spotted that the Santa with the most dough is located towards the bottom right of the picture - third row up, third from the right.
