What Do You Know about Random Number Generators?

All software producers for online casinos claim their games are based on the latest random number generators (RNG) that guarantee an unpredictable outcome.

However, can you be sure that RNG can not be decrypted? The answer may be surprising.

Let's sort out the operation principles, types of RNG, and specifics of use in online casinos.

What Is the Random Number Generator?

Let's begin with a theoretical definition:

The random number generator is a program able to produce unpredictable sequences of numbers that are not connected.

In case dice or reels used in different lotteries are primitive RNGs.

We can divide RNGs into two major categories:

1. Generators of genuinely random numbers (hardware RNG);
2. Generators of pseudorandom numbers.

The first category includes models that use the data of chaotic variations of particular physical processes. For example, the data source can be atmospheric, shot, or thermal noises.

Hardware RNGs are too expensive and complicated for the producers of casino games, so they use pseudorandom numbers. It is software designed to generate sequences of numbers.

No matter how complicated the algorithm, it doesn't produce random numbers. This is why such random number generators are called pseudorandom. They adopt the baseline figure and change it to create a new one with the help of numerous mathematical operations.

All video slots and other casino games without dealers use RNGs.

Why won't casino operators use the exact name? The answer is obvious:

No adequate marketing specialist will suggest using "pseudo" in the description of the program supposed to provide fairness and security.

Does it mean casinos trick the customers and manipulate the game outcomes? Let's avoid such strong statements and try to sort out the situation instead.

How Does the RNG Work in Casino Games?

We have described the random number generator operation's details on the example of the IGT's famous Red, White & Blue slot in "How the RNG-based slots work" at Casinoz.

We have a short explanation for those who don't feel like getting into details. The RNG returns figures in a vast range. They then transform into sets of numbers related to particular symbols. These symbols appear on the slot's screen.

RNG-based online blackjack and roulette work in a similar way.

The RNG works continuously, returning a huge number of figures every second. You shouldn't be upset if somebody wins a high payout on the slot right after you. The chances you winning it are slim.

Do Casinos Intervene in the RNG Operation?

If the random number generator is nothing more than software, it raises the question:

Can casinos fabricate the outcomes of the games?

Players are left to rely on the software producers' fairness, the honesty of gambling operators, the thoroughness of regulators, and audit organizations' professionalism.

This is why you should always choose trustworthy online casinos powered by licensed software from famous producers. Supervision of legal authorities and independent experts won't hurt either.

If you play in a doubtful online casino that doesn't report for work, you act at your own risk.

The history of gambling knows cases when gambling operators were found guilty of fraud.

• In 2008, Norman Clem suspected he'd been cheated in World Wide Wagering. Playing craps by Pass Line and Don't Pass Line, he fixed the outcomes of 3200 rolls. He won only 27% of cases, while the RTP was supposed to be about 49%.
• The scandal with BLR software captured the headlines.
• Michael Shackleford, the founder of WizardOfOdds.com, found out the producer has been artificially increasing the house edge with a simulator's help.

Be careful, and don't trust little-known developers and operators.

Who Controls RNGs in Online Gambling?

Several companies that certify random number generators are famous in the gambling world. The most reputable are eCOGRA, TST, and iTechLabs.

They execute comprehensive audits, including the operation of RNG. Then they certify the products that meet their quality criteria. Usually, online casinos publish copies of the certificates on their websites.

Besides, famous software producers don't allow casino operators to intervene in random number generators' operations. Of course, this is about licensed software.

You can be sure the RTP in a particular slot is the same in all casinos where it is presented. This is a matter of the developer's credibility, which is a big deal for the leading brands.

Is it Possible to Crack an RNG Algorithm?

Let's see if it's possible to hack a random number generator and predict the outcomes of the games.

As the RNG is nothing more than software, theoretically, it can be hacked. But is it that easy to decrypt it? Almost certainly not.

Best software developers use powerful pseudorandom number generators based on highly complicated algorithms. The chances of deciphering them are slim.

However, failures happen repeatedly, primarily if the hackers act unexpectedly.

In the 90s', Ronald Harris worked in the Gambling Authority of Nevada. One of his duties was finding errors in the slot software. He modified several slots in how they landed winning combinations in certain circumstances. His partner only had to follow instructions while playing. Harris ended up behind bars.

Summary

Could pseudorandom number generators be considered secure?

Totally. They produce results that can't be predicted.

Can you believe that casinos do not intervene in the RNG operation?

Make sure you choose trustworthy online casinos with a great experience and perfect reputation. They won't give a reason to doubt their fairness.

This is an algorithm that continuously generates sets of random figures. Combinations of these figures define the outcome of the game.

They can't if they use licensed software from famous providers.

Famous audit organizations do it.
