RNG Roulette

True RNG

To demonstrate why randomness is essential in providing a fair result, we could look at the roll of a dice or the flipping of a coin – we can never predict the outcome in these situations, which is why they are considered truly random and fair. True RNG systems always use some sort of mechanical device or physical phenomena to guarantee unpredictability. Although they are preferred and applied where possible, they are much more complex and rare due to their physical aspect.

Psuedo RNG

The most commonly used RNG systems are, in fact, pseudorandom number generators – they produce results that only seem random but are actually deterministic. Unlike true RNG, pseudo RNG typically operates through a computational algorithm that generates long sequences of apparently random numbers. These sequences, however, are based on a much shorter initial key, called a seed value.

Once the seed value is known, each long sequence can be reproduced. As we can see, this pseudo RNG cannot be regarded as a producer of truly random results. However, its use brings enough randomness and unpredictability to guarantee the reliability of crucially important systems such as modern computer encryption for security purposes.

RNG Manipulation in Games

Some casino players believe that since RNG (pseudo RNG, of course) is fundamentally a mathematical algorithm, it can be manipulated by casinos to gain an unfair advantage over patrons. We should not forget, however, that the house always has the advantage when it comes to gambling – in roulette, the theoretical house edge is 2.70% for European rules and 5.26% for American rules.

This clearly demonstrates that casinos do not need to manipulate the RNG in games to secure their income – the rules and payouts already guarantee that even if there are some very lucky players, the casino will eventually make a profit. The house edge provides gambling establishments with a long-term advantage over their patrons. This is why reputable, licensed online casinos use independently tested RNG and players can rest assured the games they play are completely fair.

Some gamblers believe that they can manipulate the RNG and secure their profits but this is not possible unless they have access to the code of the game. Others think that after observing the algorithm in a particular version of roulette, they can spot a pattern and use it to predict future outcomes. But this is also a misconception – guessing the seed value for the number sequences cannot be done unless we monitor millions of hours of play, which is, of course, unrealistic.

Fair Gaming

Nowadays, RNG is widely used in online games and in slot machines, video poker, or any other automated type of physical casino game. This was not the case, however, only a couple of decades ago when many of the games operated on different principles – slot machines, for instance, were designed to give the jackpot once in, let’s say, three months or six months. Other systems were engineered in such a way that jackpot amounts could be hit only after a certain number of rounds have been played.

But the majority of gaming machines and online games today are controlled by RNG, which guarantees that they are completely fair. While older programming and systems for paying out could be exploited by casino staff and players, the newer RNG-based software is regularly audited, with tests being performed by third-party companies. All respectable online casinos use RNG that has been certified and proven to be fair with thousands of simulations.

The Convenience of Virtual Games

Another benefit of playing RNG roulette compared to live roulette games is the convenience and variety of virtual variations. There are certain live tables with RNG-controlled wheels but most of the time, live games use mechanical wheels, real casino settings (or a TV studio), and a live human croupier. Live games come with their limitations, however.

For instance, players cannot choose the pace of the game and usually, they have up to 30 seconds to choose the preferred numbers and place their bets. There are no options such as Quick Spin or Autoplay and the game is controlled by the casino rather than the patrons. When it comes to virtual games that rely fully on RNG, players can customize the game in many different ways – change the color and design of the table, skip or play the wheel visualization, trigger Turbo Mode or Autoplay, etc.

The variety of RNG roulette games is also much greater than live versions. After all, the virtual nature of these games gives developers the freedom to create many innovative variations of the classic game such as Double Ball Roulette, Mini Roulette, Multi-Wheel Roulette, etc. RNG games also feature wider betting limits and, often, more liberal games.
