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.
Today, random number generators are actively used in various fields of human activity. However, they have gained particular popularity in, which are arranged by the owners of online stores, beauty salons, cafes and other establishments to draw profitable offers, bonuses and gifts among their subscribers. It is the random number generator that works for free online that allows you to honestly choose the winner.
If we are talking about a one-time use of the generator, you can use the simplest option such a program:
However, the computing power and functionality of such a service is not always sufficient to obtain the necessary data. To date, there are a fairly large number of specialized online programs that differ not only in the simplicity of the user interface, but also in their wide functionality. You do not have to search for dozens of programs on your own, because especially for you, in this article, we have prepared a detailed review TOP 3 best online number generators according to users:
First you need to get acquainted with the main criteria:
- Select from a list. The ability to provide the user with their own list for generation, followed by the selection of a random number from a given set.
- Select from a range. The ability of an online random number generator to sample from a specific range for free.
- Outputting multiple numbers. A function responsible for simultaneously providing several random numbers at once, if the user needs to receive more than one value.
- Disabling recurrence. The ability of the generator to exclude from subsequent generations the number that fell before it, so that when receiving several random numbers in a row, they are not duplicated.
- Website Widget. The ability to connect the generator to your website or social media page so that it is always at hand and available for work.
- Link to result. The possibility of obtaining a separate link to the result of each individual generation, which confirms the accuracy of the information provided when providing the results of contests or draws.
Before preparing this article, we analyzed many generators that are on the Internet. And out of all - chose the 3 best:
TOP-1: number generator "Randstaff"
Description: The undisputed leader of our ranking of the best random number generators is the Randstaff service. It boasts a user-friendly user interface, made in gray, which does not press on the eyes at all. It is convenient to use not only on a computer, but also using a mobile phone, which is especially important if you need to generate a random number without access to a PC.
Advantages: This free online random number generator has extensive functionality and offers the user the ability to generate any number of random numbers from a list or range without repetition. You can choose the most convenient option for using the Randstaff service yourself through a special widget, an application on social networks or the official website. After completing a simple registration procedure, you will get access to your personal account, where all your results will be securely stored.
disadvantages: Not possible. And you can save the result of the generation only for 3 days (but this is usually enough). If you want to save the result forever, you need to register in your personal account (cost - 300 rubles).
TOP 2: Castlelot Number Generator
Description: The second place rightfully belongs to the Castlelot random number generator. It is not an independent service, but part of a portal with a variety of useful things that generate beautiful rhymes, unique logins and simply store collections with interesting films or quotes. The interface differs little from similar services, but boasts wider functionality.
Advantages: Castlelot allows the user to select random numbers from a given range. It can be one or more digits. You can choose the mode of operation of the service with or without repetition. A handy advantage of the Castlelot generator is the ability to get a separate link to each result. Has an exclusive feature called "Even More Randomness". When activated, the generation process does not start until the user moves the mouse cursor to a certain position. In addition, the range of additional service tools includes a widget for the site and a proprietary VKontakte application.
disadvantages: The only obvious disadvantage of such a generator is the lack of the ability to select from a list.
TOP 3: generator "Random number.rf"
Description: The "Random number" service allows you to generate online values in the range from 1 to 99999. The design is minimalistic, which is good for it. No distractions. They are equally convenient to use on a computer or smartphone. Large black numbers on a white background are clearly visible, so even people with vision problems will not experience discomfort during its use.
Advantages: The functionality of such an online random number generator allows you to select a random value from a list and a specific range. If you need to get several random numbers online at once, the required number should be indicated in the appropriate field, where the default value is 1. The repetition is disabled at the user's request.
disadvantages: You will not be able to connect such a service to your website or community in social networks, since such a random number generator does not have its own widget. There are no links to the result either, which, together with other shortcomings, brings this service to the last place in our rating.
Conclusion
In our opinion, the best and optimal service for generating a random number is . It has all the features that other generators have. Its only disadvantage is the inability to disable the repetition of numbers during generation. But as we wrote above, this nuance is not very important for the average user. Maybe we missed something in this article? If so, write in the comments!
The online number generator is a handy tool that allows you to get the required number of numbers of a given bit depth and the widest range. There are many uses for our random number generator! For example, you can hold a contest on VKontakte and play a teddy bear there in a group of bikers for a riposte :)) We will also be very flattered if you decide to use it to determine the winning number in a lottery or decide which number to bet on in a casino . We really hope that someone will find their lucky number online with us!

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 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 presented online random number generator works on the basis of a programmatic pseudo-random number generator built into JavaScript with a uniform distribution. Integers are generated. By default, 10 random numbers are displayed in the range 100...999, the numbers are separated by spaces.
Basic settings of the random number generator:
- Amount of numbers
- Number range
- Separator type
- On / off the function of removing repetitions (doubles of numbers)
The total number is formally limited to 1000, the maximum number is 1 billion. Separator options: space, comma, semicolon.
Now you know exactly where and how to get a free sequence of random numbers in a given range on the Internet.
Random Number Generator Use Cases
Random number generator (RNG on JS with uniform distribution) will be useful for SMM-specialists and owners of groups and communities in social networks Instagram, Facebook, Vkontakte, Odnoklassniki to determine the winners of lotteries, contests and prize draws.
The random number generator allows you to draw prizes among an arbitrary number of participants with a given number of winners. Contests can be held without reposts and comments - you yourself set the number of participants and the interval for generating random numbers. You can get a set of random numbers online and for free on this site, and you do not need to install any application on your smartphone or program on your computer.
Also, an online random number generator can be used to simulate the tossing of a coin or dice. But by the way, we have separate specialized services for these cases.
