Exercising your brain and training your mind is just as important for your overall health as physical training is.

In the modern world, we often find ourselves in stressful and exhausting situations that tire us out both mentally and physically speaking.

For that reason, it is important to provide our brains with a proper mental workout that reinforces the mind and improves our ability to handle information. Luckily for you, one of the most fun ways to do that is by solving the puzzles and riddles we are sharing with you!

In today’s challenge, your job is to spot the mistake in the picture above. If you can do it in less than 20 seconds, you have a truly sharp mind.

As you can see, the picture shows a port with a docked ship. But where’s the error? Put your logic to good use and you’ll spot the mistake in no time!

Here’s a hint to set you on the right path. Something’s wrong with that dockyard. Whoever designed it should be fired right away!

While the ship fits in perfectly, the dock entrance appears to be far too small for the boat to get in our out. How are they going to get the boat out now?

If you managed to spot the mistake in the given time, congrats! If not, we have another puzzle waiting for you to help you improve your observation skills!

Focus on the picture below and, once again, try to find an error in less than 20 seconds.

Something is wrong with that watch. If you’re not familiar with Roman numerals, you should do some research now because that’s where the error lies!

As it happens, the numerals IX (9) and XI (11) switched places!
