Or what to do with a child who is bored? And this is actually a big problem of our time - children have forgotten how to play even with expensive "fancy" toys, which they usually now have in abundance, have forgotten how to play with friends in the yard, they have little company - they need a "mass entertainer", an animator. And parents sincerely believe that this is how it should be - that we and our children simply grew up at different times. But pay attention: you probably have a familiar family where the boy is passionate about sports, rides a bike all the time, plays football, in the summer he not only disappears in the river and climbs trees, but also puts up ads to earn extra money for a cool skateboard ...

And the girls aren't all busy posting their next selfie in social networks, many have time to engage in origami, which is now fashionable, go in for music and gymnastics, dance and sports, draw and go to theater studios.

And if you don’t brush off children like an annoying fly, always depicting being busy and referring to fatigue (you must admit, we often do this), but making some effort and showing interest, then you can improve life and life little man so that he will be interested and you will not be a burden!

For each person, the most difficult riddle is his own. The one over which he fought for many hours or even days. But eventually figured it out and found the answer on my own. He will never forget the clue.

But still, among those ever invented, there are those that can be confidently classified as the most intricate. They will be discussed.

The first group of puzzles: for children

Do not think that any adult can easily cope with them. Even not the most difficult riddle in the world can seriously puzzle. Moreover, there will be a big embarrassment if a child copes with it, and an adult will find it too tough.

• Life gives it as a gift twice. You have to pay for the third set. (Teeth.)
• A birch grew in the garden. There were 45 apples hanging on it. The wind blew and 9 of them fell. How many apples are left on it? (Not at all, because apples do not grow on birches.) Note. Although if a person with creative thinking comes across, he can say that nowhere is it said that apples grew on a tree. They just hung. And it is not known how they were fixed, therefore they fell.

The list of tasks that can be described as "the most difficult puzzle" continues.

• The athlete during the race overtook the one who was in second position. Where was he? (On the second, because he did not catch up with the first.)
• The same athlete in another competition overtook the last one. What position did he get? (It is impossible to overtake the latter, if someone is ahead of him, then he was not the last.)
• This thing is thrown if it is needed. And when it turns out to be unnecessary, then it is raised. What is this? (Sea anchor.)

The second group of riddles: for those who like to count

These tasks will require mathematical calculations and a little reasoning. And then any of the most difficult riddles in the world can be solved.

• A specialist is invited to a well-known company for the position of financial analyst. He is offered a starting salary of 10,000 a month. It can be upgraded in two ways. The first promises an increase of 15 thousand a year. The second guarantees an increase of 5 thousand in six months. Which option will be more profitable? (Second.) Note. You will need to calculate the salary for an arbitrary number of years. Even the first two will suffice. In both cases, the annual salary is the same - 120 thousand. Upgrade plan for the first scenario: 120k, 135k, and so on. The second scenario will give the following alignment: 60 for the first six months and 65 for the second part of the year, as a result, 125 thousand for the 1st year. Second year: 70 and 75, which will give 145 thousand per year.
• There is a heavy anchor at the bottom of the boat. She floats on the surface of the water in the pool. What will happen to the water level if the untied anchor is thrown out of the boat? (Decrease.) Note. While the anchor lies in the boat, the part of it submerged in the water is much larger than the volume of the anchor itself.

• How to draw 4 liters of water if there are only containers of 5 and 3 available? (Fill 5, pour into 3, empty the second, pour the remaining 2 from the first into it, dial 5 again, pour 1 liter from it into a three-liter.)

The third group of riddles: to speculate

Creativity is impossible without thinking carefully and moving away from the standards that society has driven people into. Therefore, the most difficult logic puzzles turn out to be simple after they are answered.

• In a large room there is a partition, behind which there are three light bulbs. Moreover, they are not visible from the remote control with three switches. It is required to determine which one is from each light bulb. You can only go through the barrier once. The solution requires two steps. The first is to turn on one light bulb and turn it off after a few minutes. During this time, she will have time to warm up. The second action is to turn on the second light bulb. Now you can look. The one that is hot is the first. The other glows - the second. And the third - the one that was not touched at all.
• One hotel has seven floors. On the first settled 4 guests. On each subsequent floor, their number increases by 3. On which floor is the elevator button most often pressed? (On the first.)
• One person had only one match left in the box. He enters a room with a kerosene lamp on the fireplace and a gas stove. What will the person light up first? (A match.)

And this is perhaps the most difficult riddle of logic.

You need to bake 6 pies. On each side they need to be fried for 5 minutes. Only 4 pies can be placed on the pan at a time. How can I cook them in 15 minutes?

The solution consists of the following steps:

• put 4 pies for 5 minutes;
• 2 turn over and remove the others, put two more, not yet fried, for another 5 minutes;
• 2 remove (they are already ready), 2 turn over and put those that were previously removed for the remaining 5 minutes.

The fourth group of riddles: ingenuity

They require ingenuity. A savvy person will easily solve all the most complex logical riddles.

• The girl took out a ring from a cup of coffee. Why didn't the ring get wet? (Coffee in powder, granules or beans.)

• One businessman bought apples for 6 rubles, and sold them for 4. How did he manage to become a millionaire? (Before this action, he was a billionaire.)
• The steamer moored at the pier, and the 4 lower steps were in the water. The thickness and height of the steps: 5 and 30 cm. While the steamer was at the pier, the tide began, and the water arrived by 40 cm every hour. How many steps will be under water 3 hours after the start of the tide? (Still 4, the steamer will rise with the water.)

Fifth group of riddles: with a trick

In solving such problems, logic and the ability to count well will not always help. These most difficult riddles - with a catch. That is, those in which you need to look for something unusual.

• Three tractor drivers work on the collective farm, who have a brother Sergei. But he has no brothers. How can this be? (They are sisters.)
• There were 10 candles on the candlestick. The hostess blew out 3 of them. How many candles will be left by morning? (3: those that are blown out will not burn.)
• It is now 12 o'clock at night. It is raining outside. How confident is it that the sun will shine in 72 hours? (Not at all, it will be night again.)
• In what situation is it easier for a black cat to enter the house? (When the door is open.)

And some more mysteries

• It is impossible to keep it for more than 5-10 minutes. But at the same time, it weighs almost nothing (Breathing.)
• There were so many apples on the plate that there were enough for all the children. How did it happen that all the guys took one at a time, but one was left on the plate? (The latter took it along with the plate.)

And here is the most difficult riddle, which has two solutions.

The patient needs to leave for 30 days. The doctor gives him two medicines of 30 tablets. They can not be distinguished by color, taste, smell, shape and size. It is impossible to interrupt the course of treatment. Every day you need to take one tablet of each drug. One day, a person took out 1 tablet from the first package, and 2 fell out of the second. They mixed up. How can the patient follow the doctor's recommendations?

1. Take another tablet from the first one. Cut everything in half and put all the left halves in one direction, and the right halves in the other. So it turns out that in each pile there will be one of each type.

2. Again, take another pill. Grind everything into a powder and divide into two equal parts.
