Brainteasers are a fantastic way to challenge your mind and sharpen your focus, often requiring you to think outside the box to solve the riddle.

According to the website, only those with high IQs can complete it within the time limit. The puzzle consists of nine rows and 31 columns, mostly filled with the letter X.

Your task is to spot six hidden Ys randomly placed within the sequence. To ramp up the difficulty, you only have 13 seconds to scan all the rows and columns to find the answer.

Puzzles like these are a simple test of your observational skills. It's challenging because it requires you to swiftly focus your mind, using your brain power to locate all the letters within the time limit.

Remember, this is a fun way to test your IQ, but an actual test is the only way to know your true level. Did you manage to find all six Ys?

If you're still struggling, we've posted the answer below so you can check.

If you found that too straightforward, we've got more letter-based brain teasers with varying time limits to challenge your mental prowess. If 13 seconds was just about manageable for you, we have another one with the same time limit.

However, in this one, you only need to find one odd letter – which might not be as simple as it seems. If that time limit is a bit challenging for you, there's another one that gives you 21 seconds, but you'll have to locate one X hidden among the Ys.

What makes this one even more difficult is that they are all in different colours.
