Simple random number generators. Random number generator

Numbers accompany us everywhere - the number of the house and apartment, telephone, car, passport, plastic card, dates, email passwords. We choose some combinations of numbers ourselves, but we get most by chance. Without realizing it, we use randomly generated numbers every day. If we invent pincodes, then unique credit or salary card codes are generated by reliable systems that exclude access to passwords. Random number generators provide protection in areas requiring processing speed, security and independent data processing.

The process of generating pseudo-random numbers is subject to certain laws and has been used for a long time, for example, when conducting lotteries. In the recent past, drawings were carried out using lottery drums or lots. Now in many countries the winning numbers of state lotteries are determined precisely by a set of generated random numbers.

Advantages of the method

So, the random number generator is an independent modern mechanism for randomly determining combinations of numbers. The uniqueness and perfection of this method lies in the impossibility of external interference in the process. The generator is a set of programs built, for example, on noise diodes. The device generates a stream of random noise, the current values ​​of which are converted into numbers and make combinations.

Number generation provides instant results - it takes a few seconds to complete a combination. If we talk about lotteries, participants can immediately find out if the ticket number matches the winning one. This allows draws to be held as often as participants wish. But the main advantage of the method is unpredictability and the inability to calculate the number selection algorithm.

How pseudo-random numbers are generated

In fact, random numbers are not random - the series starts from a given number and is generated by an algorithm. A pseudorandom number generator (PRNG or PRNG - pseudorandom number generator) is an algorithm that generates a sequence of, at first glance, unrelated numbers, usually subject to a uniform distribution. In computer science, pseudo-random numbers are used in many applications: in cryptography, simulation, Monte Carlo, etc. The quality of the result depends on the properties of the PRNG.

The source of generation can be physical noise from cosmic rays to resistor noise, but such devices are almost never used in network security applications. Cryptographic applications use special algorithms that generate sequences that cannot be statistically random. However, a well-chosen algorithm produces series of numbers that pass most tests for randomness. The repetition period in such sequences is greater than the working interval from which the numbers are taken.

Many modern processors contain a PRNG, such as RdRand. As an alternative, sets of random numbers are created and published in a one-time pad (dictionary). The source of numbers in this case is limited and does not provide complete network security.

History of the PRNG

The prototype of the random number generator can be considered the board game Senet, common in ancient Egypt in 3500 BC. According to the conditions, two players participated, the moves were determined by throwing four flat black and white sticks - they were like a PRNG of that time. The sticks were thrown at the same time, and the points were counted: if one fell up with the white side, 1 point and an additional move, two white ones - two points, and so on. The maximum result of five points was received by the player who threw four sticks with the black side.

Today, the ERNIE generator has been used in the UK for many years in lottery draws. There are two main methods for generating winning numbers: linear congruent and additive congruent. These and other methods are based on the principle of randomness of choice and are provided by software that produces numbers indefinitely, the sequence of which cannot be guessed.

The PRNG operates continuously, for example, in slot machines. Under US law, this is a mandatory condition that all software vendors must comply with.

The Random Number Generator for Lottery Tickets is provided free of charge on an "as is" basis. The developer does not bear any responsibility for the material and non-material losses of the users of the script. You may use this service at your own risk. However, something, but you definitely don’t take risks :-).

Random numbers for online lottery tickets

This software (PRNG in JS) is a pseudo-random number generator implemented with the capabilities of the Javascript programming language. The generator produces a uniform distribution of random numbers.

This allows the lottery company to beat out a “wedge with a wedge” on an evenly distributed RNG from a lottery company to respond with random numbers with a uniform distribution. This approach eliminates the subjectivity of the player, since people have certain preferences in choosing numbers and numbers (birthdays of relatives, memorable dates, years, etc.), which affect the selection of numbers manually.

The free tool helps players to pick random numbers for lotteries. The random number generator script has a set of preset modes for Gosloto 5 out of 36, 6 out of 45, 7 out of 49, 4 out of 20, Sportloto 6 out of 49. You can choose a random number generation mode with free settings for other lottery options.

Lottery winning predictions

A random number generator with a uniform distribution can serve as a horoscope for the lottery, however, the probability that the forecast will come true is low. But still, using a random number generator has a good chance of winning compared to many other lottery game strategies and additionally frees you from the pain of choosing lucky numbers and combinations. For my part, I do not advise you to succumb to the temptation and buy paid forecasts, it is better to spend this money on a textbook on combinatorics. You can learn a lot of interesting things from it, for example, the probability of winning the jackpot in Gosloto is 5 out of 36 1 to 376 992 . And the probability of getting the minimum prize by guessing 2 numbers is 1 to 8 . The forecast based on our RNG has the same winning probabilities.

On the Internet, there are requests for random numbers for the lottery, taking into account past draws. But provided that the lottery uses an RNG with a uniform distribution and the probability of getting one or another combination does not depend on the draw to draw, then it is pointless to try to take into account the results of past draws. And this is quite logical, since it is not profitable for lottery companies to allow participants to increase the probability of their winning by simple methods.

There is often talk that lottery organizers rig the results. But in fact, this makes no sense, even, on the contrary, if lottery companies influenced the results of the lottery, then it would be possible to find a winning strategy, but so far no one has succeeded. Therefore, it is very beneficial for lottery organizers that the balls fall out with a uniform probability. By the way, the estimated return of the lottery 5 out of 36 is 34.7%. Thus, the lottery company has 65.3% of the proceeds from ticket sales, part of the funds (usually half) is deducted for the formation of the jackpot, the rest of the money goes to organizational expenses, advertising and the company's net profit. The circulation statistics confirm these figures perfectly.

Hence the conclusion - do not buy meaningless forecasts, use a free random number generator, take care of your nerves. Let our random numbers be your lucky numbers. Good mood and good day!

The program is an online random number generator for Russian lotteries 5 out of 36, 6 out of 45, 7 out of 49, 6 out of 49. In addition to the number generator, such a useful tool as "Number Exclusions" is attached.
Are you unlucky with the number 7 or 10? Then you can simply add these numbers to the exceptions, and they will not be taken into account when generating numerical options.

Of course, I understand that gamers are superstitious people, but I’m just wondering, what’s the difference, will I come up with these numbers myself, or will this numerical generator give them to me?

2. Max 04.06.2014
Sergius, of course, you yourself can come up with numbers. But when compiling them, you will still be subject to a certain sequence that will be influenced by factors such as favorite numbers, or just a number spinning in your head. That is, the numbers you come up with will be conditionally random.

The computer program is completely free from third-party interference and generates truly random numbers.

3. Iloinor 17.06.2014
When drawing in the same lottery, 5 out of 36 balls from the lottery drum fly out randomly. And their combination can be absolutely any. So it is simply impossible to generate a more or less successful combination. Any combination of numbers will always have the same winning ratio.
Who thinks otherwise?

4. Alexander 08.07.2014
Absolutely any hand-generated or compiled by the player himself has a probability of 1 in 376,992 (for the lottery 5-36). In theory, it has such a possibility! Those who think long enough on the problem of “how to increase the probability” will not agree with me.

And I came to the conclusion that it’s not so hopeless in fact. If you look at how the combinations play in the full array of the same 5 out of 36, you can see that the combinations play with equal probability over a sufficiently long period of time.

At the same time, as if clusters are observed (we looked at the starry sky), there is also a random distribution. We see that the stars are clustered in certain places, but if you look through a telescope, then the equiprobable distribution is preserved.

Yes, let's get back to the lotteries, if you look at such a card (combinations that have played), you can see that some areas “seem to have quieted down”, such narrow ranges become more likely than others for the next games. Since, according to the law of equiprobable distribution, this area should be filled in the very near future. It makes sense to wait for combinations there. Our probability increases dramatically. We have a strategy that is aimed at the railway pot. This is a purposeful game, not blind throwing.

This is where special programs come in handy.
Contact the author of the random number generator posted here. It can offer a special visualized game program + built-in strategy.

"I certainly understand that gamers are superstitious people"

Not that word. My uncle always rubs all the purchased Russian Lotto tickets on the sleeve of his happy old jacket.

9. Nicholas 25.10.2015
Chance and luck speak. Of course, who argues.
Did you imagine the number of combinations, for example, in the lottery 6 out of 45?
If you clearly and clearly imagine this number, it will become obvious that it is not advisable to rely only on chance and luck.
Turn on just a little fantasy, I hope you are not going to argue that we can turn on natural cunning and just accidentally exclude one single number from 45.
At the same time, you need to try very hard not to catch the prize money. The chance of such an event will be 1 in 7.5.
Now we consider that we successfully excluded this number, in this case we have not 8,145,060 combinations left for the game, but 7,059,052 ... that is, we reduced 1,086,008 from the range of possible combinations (more than a million combinations) with one single number.
This simple example illustrates the meaning of exceptions. And one should not think that people who have devoted considerable time to studying the methods of playing in numerical lotteries write one “vomit”.
Everything is mathematically justified.
Of course, Luck plays an important role in numerical lotteries, since we bet a very small number of combinations for the game.
Therefore, in order to make it easier for “Luck” to find you, you need to use some game methods that are designed to PROBABLY cut as many combinations as possible from the full array of the selected lottery.

10. Igor CK 03.09.2016
Here Nikolai wrote above about the exclusion of one number in order to increase the chances that the rest of the numbers will fall out. In theory, this is all true! If, say, we exclude not 1, but 3 numbers, then the chances will grow even higher.
BUT there is one BUT! This is a lottery, everything is random and unpredictable. One and the same number can fall out 10 times in a row, and the other one cannot fall out even in 100 variants! It is impossible to calculate these very numbers, that's the point.

I remember at the time of studying at the university, our teacher in higher mathematics, a pleasant and intelligent man, talked about lotteries and accidents. So he said that it is impossible to draw up any systems and methods here in principle! The result is completely random and unpredictable.

I saw several paid programs and training methods on the net that “help” make the right combinations of numbers that increase the chances of winning. Do you know what I'm curious about? If there is a way to increase the chances of winning, then why don't those who sell them make money on lotteries? Yes, it will not work to cut down the jackpot, the probability is too small, but it is quite possible to win small amounts. Isn't it logical?
Of course, they can object to me - they say, one does not interfere with the other - to earn money on lotteries and on the sale of techniques. But the fact is that if everyone uses these techniques, provided, of course, that they really work, then this will reduce the income from winnings for their creators, since they will have to be divided among a large number of people.

It's like finding a hole in the Webmoney system that allows you to replenish your wallet with money "out of nowhere" and put this technique up for sale so that it would be covered as soon as possible.

11. home 04.09.2016
Igor CK, what Nikolai wrote there - he wrote about one number, and the chances of not hitting the prize.
Count further, what will be the chances, if the 2nd number is excluded, not to catch the future prize money, and so on))

Naturally, they cannot be excluded indefinitely, there are no fantasy and fairy tales in lotteries, unless on fabulous sites that catch "seekers"))
Here we need a different approach, we need to follow not the numbers, but the periods that these numbers form.
Well, then build a strategy, and become attached to the history of circulation.

I decided to make a version of the generator for the mass user, and I will upload it for moderation today tomorrow.
On my website, I will open the page of this generator, and there I will try to set out a game strategy that uses the frequency of full and partial matches.
Winning the number lottery is difficult, but it is possible.

12. home 13.11.2016
In general, I wrote the basics on the site, which can be found on request: "VISUAL GENERATOR - random number generator with an exception." I paid a lot of attention to probabilities.
I made a version for this game strategy, which can be downloaded on the site, or here - VISUAL LOTTO TESTER 3.1

13. Timofei 26.11.2016
My friend at work won 63 thousand rubles in the lottery. Walks happy as a boa constrictor. And I have no luck at all. If you are lucky to win something, then one small thing.

14. Max 26.11.2016
The guys have a wonderful program "Eurolotto Win Generator All Lotteries of the World" - there are algorithms for calculating circulations, the game won 15,000 rubles and completely recouped the cost and also earned!

15. Yuri 01.02.2017
Let's try to play and see what happens.

16. Alexander 04.06.2017
I read not so long ago in a live journal (I don’t remember the exact address of the diary) analytical calculations about lotteries in Russia. The bottom line is that the results of large winnings are manipulated and those who play are shown already known combinations. In general, the jackpot does not threaten us with you.

The information is based on the calculation of the chances of winning, the number of participants in the drawing and the number of winnings. So if you take the number of participants and calculate the chance of winning the jackpot, then you get a huge gap between chance and reality.

If, for example, you take a random number generator and guess any number from 1 to 10, then you have a 1 to 10 chance of guessing. In Russian lotteries, with the same scheme, the chance of a big win is 1 to 40-50. And it remains to be seen how real the person who wins the jackpot is.

17. home 04.06.2017
Complete nonsense is spread by pseudo-analytical mathematicians.
It can be assumed with a high degree of probability that this is a struggle between competitors (ticket distributors).
As well as people who have already finished playing before, and have read that they really think: how is it - I think, I think, and I think again ... and sawing, I can’t count in any way.)
That is, they blame third-party forces for their failures, which do not allow to calculate in any way, well, no matter how.
Do you know where you can calculate something up to fractions of a second? For example, in celestial mechanics - an eclipse of the moon - for millennia ahead - based on past observations.
This, as we all know, was used by priests who learned to predict such events.

In lotteries, alas, there are no even intervals, for example, the fall of a certain ball. Since we have an accident, and not a clear celestial mechanics.
That is, if the chance of the number is 1 to 10, then it will play at random - somewhere, going into a deep pause, somewhere it will often, BUT if we take a large number of tests, then on average the number will fall out 10 times per draw.
Probability levels out.
I read calculations about jackpots.
Calculators took a fixed segment of the circulation history - they looked at how many jackpots they took - they looked at how many bets they bought.
Simple division - and here the result does not converge. That is, for example, in the lottery, 5 out of 36 jackpots must be played for every 376,992 bets)
It turned out, for example, played 10, but should be like 20)
They take a different segment of the circulation history, and repeat the calculation - and lo and behold, there is even more than calculated - it means it was honest there - and even the orgies gave more - like lure.

Let's remember about a single number - paint on a time period (on a sheet of paper), the history of the coincidence of a number, for example 33, for 150 runs.
Now divide this segment into, say, 3 equal parts. Count the number of matches in each part. You will see that there will be a different number of matches.
But on average for the entire segment, the probability will be close to the calculated one.
150 copies is clearly not enough.

Now, none of the calculators will agree to calculate, say, for 3000 runs in 5 out of 36. This is titanic manual labor (you need to look at the site for the number of purchased bets and fix jackpots).
I am convinced that on average, for such a number of circulations, the probability will be close to the calculated one.

18. Cossack 03.07.2017
I’m wondering how Stoloto differs from Casinos banned in the Russian Federation? Essentially the same bets on the number. Oh yes, just a different name))) Well, okay, God bless him with the name. Here in the reviews they are hotly discussing the possibilities and chances of winning the lottery, they even made a combination generator. But where are these real people who win Jack Pots and big wins? I recommend watching a few videos on YouTube about organizing Stoloto lotteries, a random number generator (RNG), the so-called live broadcasts, etc.

Answer:
People always want to win a lot of money for free. Any tote is built on this. To play or not, to believe or not, everyone's business. Link to video regarding Stoloto

It's been about a year since I got hooked on the lottery. I understand intellectually that I have almost no chance of winning the jackpot, but I just can’t tear myself away from the game.

20.Jobbs 12.07.2017
How to calculate the probability of getting one number out of 100

Answer:
The meaning of the question is not entirely clear. If we take a completely random, random loss, then the answer is quite obvious, the chances will be 1 in 100 for any number from 1 to 100.
If you are talking about random number generator (RNG) algorithms, does any programming language have its own operator responsible for generating them? It is difficult to say how random it is, because some algorithm is still responsible for its work, which in itself excludes complete randomness. However, the end result is close to perfect.

21. Kirill 05.09.2017
Do not believe in the possibility of winning significant money in the lottery. All the money has long been cut down. Search the web for information about the owner of Stoloto and how much money is spinning there. In addition, all broadcasts are recorded. You can return any result. Jack pots get dead souls.

22. Nicholas 23.10.2017
What are you talking about! At the expense of the network, for example, you can find information on the network that the Earth is flat, and it turns out that everyone is deceived that it is a ball ... and a lot more can be found!
Have you ever seen the odds of winning? Can you imagine what it is all about? In lotteries, there is no need to "squeal", since the probabilities will not allow the lottery to go bankrupt, the organizers will always be in profit.
And so that there were no doubts, or that they were minimal, the Russian state lotteries were transferred to automatic lottery drums, which no one approaches during the draws. Lototrons are installed behind glass in the lottery center. Now those who wish can see with their own eyes the work of these lottery drums - admission is free. By the way, there is no such openness anywhere else in the world.

news on the website stoloto.ru - the official website of Russian lotteries

Answer:
They themselves wrote about the fact that they write about flat earth on the network and at the same time refer to the data on the network)))

23. lucky dude 26.10.2017
Bullshit, bullshit and more bullshit. Lady luck and nothing more. Try to take the combination given to you and beat it in the archive lottery and see the matches that were in previous draws. Although who knows, maybe someone else will get the same bet taken from here. For everything by chance

The author on the program page gave links to the lottery forum, where he made tests.

25. Semem Semenych 20.12.2017
>>> It is unlikely that you will find the authors of lottery programs who will publicly conduct tests, and even on lottery forums where the players are not stupid at all, who have gone through hundreds of free and paid programs.

I would say otherwise. It is unlikely that you will find avid lottery gamers with high intelligence. Of course, they can buy 1-2-3 tickets for fun, but people are well aware that it is simply unrealistic to win serious money in the lottery, especially in Russia.

26. Pavel 27.12.2017
High IQ players don't play multiple tickets - not even for fun. Such players understand the theory of probability very well, which for most ordinary people is a Chinese letter. Such players play systematically, carefully calculating their chances and budget for the game. These players develop strategies for the game. Such players never bet at random.

As for winning big prizes in Russia, this is just your attitude, so to speak, not supported by any facts. Learn more about probability theory. It is highly unlikely that your neighbor will hit the jackpot and then share this information with you. I will say differently - in Russia it is dangerous to shine with a big win)))

27. don't play 05.01.2018
Pavel, people with high intelligence are well aware of what is a scam and what is not. And yes, intelligence allows them to make money with a much greater degree of probability than a lottery.

28. Alexander 16.01.2018
You can’t win in the table, there is a program for sold tickets

29. Mechanic 09.06.2018
Don’t fool your heads, just take a screenshot of the lottery from the site and check after the drawing there is a win, but they are cheap, I checked thousands of updates, I was tortured

I offer free and paid programs for analyzing lotteries: Keno, matchball, 5/36, 6/45, 6/49, 7/49, Russian lotto and others. There is a built-in generator of combinations of given numbers, a win and jackpot generator, the ability to print lotto cards and much more. Download here [removed]

31. Ilya Nefedov 13.08.2018
Guys, no one will make you a gosloto win generator 5 out of 36, etc. even taking into account past draws. Everything is clear about the chance of random numbers falling out. BUT! Only if they are truly random. And when the winning combinations are generated by a computer that already knows which combinations the players have chosen, then I don’t believe in the honesty of its algorithms. It's the same as playing in an online casino, where the roulette generator already knows what bet you've made.

32. Albert 08.11.2018
the program does not work at all, those numbers that are not needed are scored. raw in one word

Answer:
I introduced several different sets of exception numbers, ran it several dozen times in different modes. The indicated numbers never appeared in the result. Do you have it differently? Or did I misunderstand you?

33. Albert 11.11.2018
how many digits can be hammered into exceptions? I scored 30 there were replays from elimination

Answer:
There are no restrictions. Do you separate the numbers with a comma?
I add the following line to the exceptions:
1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30

Result: There are no excluded digits in the final result.
If your situation is different, please indicate your sequence and also your browser so that you can accurately recreate your situation.

34. Albert 14.11.2018
browser Opera.there are repetitions of those numbers that are typed in the exception
1.2.3.4.5.6.8.10.11.13.14.15.16.17.18.19.20.22.24.26.28.29.30.31.32.34.36.37.38.39.40.41.43.46.47.49.

Answer:
Your numbers are separated by a dot, not a comma. It should be like this:
1,2,3,4,5,6,8,10,11,13,14,15,16,17,18,19,20,22,24,26,28,29,30,31,32,34,36,37,38,39,40,41,43,46,47,49
This combination works.

To generate random numbers in the range you need, it is best to use the Online Random Number Generator. The presence of a large number of options will allow you to select the required number of random numbers, as well as specify the final and initial value.

Online number generator (randomizer) instruction:

By default, the random number generator is entered with 1 number. If you change the application settings, you can simultaneously generate up to 250 random numbers. First you need to set the range. The maximum value of a number is 9,999,999,999. The random number generator allows you to order numbers in descending, ascending, or random order.

To display the result, you can use different separators: semicolon, comma, and space. In addition, repetition is possible. The "Exclude repetitions" option will allow you to get rid of duplications. You can also send a link to the calculations made by messenger or e-mail by copying the "Link to the result".

Various lotteries, drawings, etc. are often held in many groups or publics on social networks, Instagram, etc., and are used by account owners to attract a new audience to the community.

The result of such draws often depends on the luck of the user, since the recipient of the prize is determined randomly.

For such a determination, draw organizers almost always use an online random number generator or a pre-installed one that is distributed free of charge.

Choice

Quite often, it can be difficult to choose such a generator, since their functionality is quite different - for some it is significantly limited, for others it is quite wide.

A fairly large number of such services are being implemented, but the difficulty is that they differ in scope.

Many, for example, are tied with their functionality to a particular social network (for example, many generator applications on VKontakte work only with links of this social network).

The simplest generators simply generate a random number within a given range.

This is convenient because it does not associate the result with a specific post, which means that they can be used for draws outside the social network and in various other situations.

They don't really have any other use.

<Рис. 1 Генератор>

Advice! When choosing the most suitable generator, it is important to consider the purpose for which it will be used.

Specifications

For the fastest process of choosing the optimal online random number generation service, the table below shows the main technical characteristics and functionality of such applications.

All applications discussed in the table are described in more detail below.

<Рис. 2 Случайные числа>

randstuff

<Рис. 3 RandStuff>

You can use this application online using the link to its official website http://randstuff.ru/number/.

This is a simple random number generator, characterized by fast and stable operation.

It is successfully implemented both in the format of a separate independent application on the official website, and as an application in the VKontakte social network.

The peculiarity of this service is that it can choose a random number both from the specified range and from a specific list of numbers that can be specified on the site.

Pros:

• Stable and fast work;
• Lack of direct link to the social network;
• You can select one or more numbers;
• You can only choose from the given numbers.

Minuses:

• The impossibility of holding a draw on VKontakte (this requires a separate application);
• Applications for VKontakte do not run in all browsers;
• The result sometimes seems predictable, since only one calculation algorithm is used.

User reviews about this application are as follows: “We determine the winners in VKontakte groups through this service. Thank you”, “You are the best”, “I use only this service”.

Cast Lots

<Рис. 4 Cast Lots>

This application is a simple function generator, implemented on the official website, in the form of a VKontakte application.

There is also a generator widget to embed on your website.

The main difference from the previous described application is that this allows you to disable the repetition of the result.

That is, when conducting several generations in a row in one session, the number will not repeat.

• The presence of a widget to insert on a website or blog;
• Ability to disable the repetition of the result;
• The presence of the function "even more randomness", after the activation of which the selection algorithm changes.

Negative:

• The impossibility of determining several results at once;
• Inability to select from a specific list of numbers;
• To select a winner in public, you must use a separate VKontakte widget.

User reviews are as follows: “It works stably, it is quite convenient to use”, “Convenient functionality”, “I use only this service”.

Random number

You can use this random number generator at http://randomus.ru/.

Another simple one, but functional random number generator.

The service has sufficient functionality for determining random numbers, however, it is not suitable for holding draws and other more complex processes.

Negative:

• The impossibility of holding draws based on post reposts, etc.
• There is no application for VKontakte or a widget for the site;
• It is not possible to disable repeating results.
