Only the most clever readers will be able to spot every mistake in this tricky puzzle as the clock counts down from 17 seconds.

Optical illusions and puzzles not only give you bragging rights by demonstrating your brain power, but they have also established themselves as an effective means of training your grey matter and can even have a positive effect on your mental health. Today’s task shows a picture of an antique shop, but all is not well in the vintage store. Only people with a high IQ will be able to spot all eight hidden errors in less than 20 seconds. A person’s IQ is a measure of their reasoning ability and is designed to measure how well they can use information and logic to answer questions.



Looking at the image, three people can be seen inside the antique store looking at their wares. The shoppers, like many viewers, can’t see the strange items that don’t belong there. Spoilers follow as we point out the mistakes in this difficult trailer.

If you look to the top left of the picture, you’ll see a tiger’s head hanging on the wall – a hunter’s prey. But this tiger has a pair of horns on its head. Tigers don’t have horns. Moving on to the left, but coming to the front of the picture, there’s a chessboard on the table as one of the men checks to see who’s been making the best moves. There’s a mistake here too. The number of squares on the chessboard adds up to 49 (7×7) instead of the usual 64 (8×8).

Next, there are a couple of animal-related errors. Among the objects is a dog lying on the couch, but its tail looks more like a cat’s than a dog’s. And the fish tank is filled with butterflies. The youngest person in the picture is a boy on the right who appears to be browsing the books on offer, but if you look at his shirt, one arm has a long sleeve while the other is a three-quarter sleeve. Across the room is a guitar on a table, but its head looks more like that of a sitar player. The windows that open onto a city scene outside are also strange, with one opening inward and the other outward. Then, the man in the painting in the center of the picture appears to be wearing only one shoe.
