You're officially smart if you can complete three brainteasers in less than 30 seconds

Test your eyesight with a brainteaser that over half of participants take longer than 30 seconds to solve.

The challenge involves spotting seven dogs cleverly camouflaged in a park scene. The puzzle, created by Spin Genie, proved tricky for many, with 38% of people taking more than 30 seconds to find all the dogs and 15% taking over a minute.

Some dogs are easier to spot than others due to their background, while some are cunningly hidden within the scenery. One dog is particularly elusive as it blends into the trees in the centre of the image. Ready to play?

With the answers highlighted, it's revealed that three dogs are nestled among the trees, three are wandering around the park in the foreground, and the seventh is being painted by a woman at the front of the picture.

If you're up for another challenge, try finding the six unique cups or drinks among a list of 400. Many have found this puzzle easier, with the odd ones out - a green drink, two red ones, and pink and blue cups - standing out more clearly.

According to Spin Genie, 80% of participants in the second game were able to spot the drinks in under 10 seconds. If you're still struggling with this one, brace yourself as the answer is coming up in the image below.

The final challenge is a tad more difficult than the second, where eight leaves have to be singled out from the rest. However, this time not all the background is the same, with some leaves pointing upwards and others downwards.

Upon closer inspection, you can spot the eight leaves which are all slightly different in colour while their shapes are also distinct. A whopping 61% of people were able to spot the unique leaves in just under 10 seconds!
