Here is the latest mind-boggling puzzle which has the internet in the spin – featuring Her Majesty herself.
The image features identical 50p-style coins .. apart from one where the Queen is WINKING instead of staring straight ahead.
The puzzle was created by over-50s insurance experts SunLife as part of its Welcome to Life After 50 campaign.
Ian Atkinson, marketing director at SunLife, said: “The 50p pieces may be getting you into a state in this puzzle, but in reality, turning 50 is having quite the opposite effect on people.
“As part of our Welcome to Life After 50 campaign we have interviewed 50,000 people in their 50s, 60s and 70s about their lives and have found they are enjoying life more than ever
“On average, people over 50 say they feel 10 years younger mentally and one of the ways they try and stay young is by keeping their minds active, so this puzzle is the perfect way to get that grey matter going!
“We want to celebrate life after 50, because for many, life after 50 is the best time of their lives.”
