Of course, parents do not always want to bother their precious child and come up with the most difficult riddles for him. Nevertheless, such questions, which require reflection, are useful and necessary for children and adults, regardless of age.
Why ask a child difficult riddles
Moms and dads may wonder whether it is worth misleading a child and including difficult tasks in the program. However, having studied the information about how productive the most difficult riddles are for children of different ages, parents will immediately change their minds. Logic and trick puzzles are needed for the following reasons:
These are just some of the factors that indicate that children definitely need difficult questions that need to be answered. This will help you develop fully and be literate.
What should be the riddles
It is clear that complex riddles are somewhat different from simple logical questions. It is necessary to think over the program of a developmental lesson with such tasks in advance so that the process goes smoothly and without a hitch. The hardest riddles should be:
- With a trick.
- Are ambiguous.
- The kind that deserves a lot of thought.
- Difficult riddles should be selected according to the age of the child. This will help boys and girls find answers according to their level of knowledge. It follows that kids should not make very difficult riddles; for the smallest, it is better to choose questions with a trick. For older children, you can choose questions such as for adults.
It is worth considering the above factors when choosing logical questions for your child.
Logic puzzles for the little ones
For children up to school age you can take into account the following riddles:
Three apples grew on a birch, and five pears grew on a poplar, how many fruits are on these trees?
(Not a single one, fruits do not grow on birch and poplar)

(under wet)
Which fields do not grow a single plant?
(On the brim of the hat)
Such complex logic puzzles for the little ones will cause a whirlpool of emotions and interest. The most important thing is to give the child hints, thanks to which he will be able to find the correct answer.
Difficult riddles with a trick for schoolchildren
School-age children can pick up questions even harder. Very complex ones can be:
You are in a running race. When you overtook the one who ran last, what did you become?
(This cannot be, because the last runner cannot be overtaken, because he is the last one and there cannot be someone else behind him)
Three car owners had a brother, Alyosha. But Alyosha did not have a single brother, how is this possible?
(Perhaps if Alyosha had sisters)
What will you become in a row if you overtook the second runner in line?
(Many will answer first, but this is wrong, because having overtaken the second runner, a person will become the second)
Such complex riddles with a trick will certainly appeal to schoolchildren. After thinking about the answer, it will be easy to voice it.
Adult riddles with a trick
Sometimes adults are like children. Therefore, they will also like very complex riddles. For people older than school age, you can ask the following logical questions:
There is a tram with five passengers. At the first stop, two passengers got off and four got on. No one got off at the next stop, ten passengers got on. At another station, five passengers entered, one got off. On the next - seven people left, eight people entered. When there was another stop, five people got off and no one came in. How many stops did the tram have?
(The answer in this riddle is not so important. The bottom line is that all participants will most likely count the number of passengers and hardly anyone will decide to count the stops)
The doorbell is ringing. You know that your relatives are behind it. There's champagne in your fridge cold water and juice. What will you open first?

So the first of those who escaped died. When the second prisoner was attempting a disaster, sentries noticed him and dragged him by the hair into the prison area, where he was shot. The third prisoner escaped normally and was never seen again. What's wrong with this story?
(There are no sharks in the river, the prisoner could not be dragged by the hair, because they shave their heads)
Such riddles will appeal to adult participants in the event.
How to motivate a child to participate in a developmental activity
It is clear that children definitely need motivation in order for participation in the game to be exciting and desirable. It is enough just to promise the baby some kind of present and, of course, hand it over at the end of the game.
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's 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.

8. What number will be next in this series: 1, 11, 21, 1211, 111221, 312211, ...
Answer 8:
13112221
· Each sequence of numbers is a verbal representation of the sequence that comes before it. So, for example, starting from one, the next sequence would be "one 1" or "11". It will be followed by the sequence "two 1" or "21" and so on.
· The first digit is 1 (amount) "1" (number from 0 to 9). So if you say "One 1", the next number will be "11". Now it turned out "two 1" or "21". After that "one 2 and one 1", which gives us 1211. Then "one 1, one 2 and two 1", which gives us 111221 and so on.
