Are online casinos fair to play? How can we be so sure that we are not playing at rigged gambling platforms?

One of the justified reasons that online casinos are a fair platform to gamble is the RNG technology theory. The RNG or Random Number Generators are significant aspects of the gambling industry. It's fair to say that technology is the heartbeat of the online casino market as it is impossible can guarantee fair play without them.

When visiting land-based casinos, you will find dealers shuffling the cards and randomising their actions. When dealers are not part of every game online at online casinos, the process of shuffling is replaced with a mathematical formula ensuring players that every wheel-spinning action, card dealt, and dice rolled is not pre-planned.

What Is the Random Number Generator?

When playing on online casinos and you want a random number, you will have to use the land-based casinos' traditional method. At first, there were only rolling dice, flipping coins, or drawing card methods to choose a random number.

When things accelerated, many random numbers demanded the RNG feature's computerised version in the casino market. Online casinos using RNG technology are known to use PRNG (pseudorandom number generator). With this algorithm, it becomes possible to create a long string of random numbers spontaneously; however, the seed restricts the series, which is the fixed number. Developers control the RTP rates by manipulating the sources on online casinos.

It's best to read this information to explain RNG in simpler terms:

  • RNG is responsible for keeping every spin, card shuffle and dice rolling fair.
  • RNG is part of most online casino games and is a crucial aspect of many offline slot titles.
  • RNGs powered by extended seed numbers that are almost impossible to crack.
  • You can trust independent auditors to test the fairness and accuracy of RNGs regularly.
  • All the authentic online gambling sites display the test certificates and layout for public view.

Is Online Casino RNG Fair?

The first thing when joining an online is to test their legitimate status. All the reputable online casinos are regulated and licensed by authentic authorities. 3rd parties do the audit, which is independent in their decision, such as TST. Technical Systems Testing or TST is an accepted company owned by GLI or Gaming Laboratories International.

The audit companies offer a full expansion of consulting and testing to online casinos to approve them as fair gambling platforms. They perform a set of testing and evaluations, which include:

  • Evaluation of Random Number Generator
  • Evaluation of game and mathematics
  • Reporting and verification of game layout or ongoing RNG
  • Evaluation if betting exchange, sportsbook or live dealer.
  • Audits of poker system
  • System evaluation of pari-mutuel and lottery
  • Extended security audits and penetration testing

The online casinos that used the most robust evaluation process get the approval badge by the company stamping them as fair gambling platforms. Such online casinos are called RNG casino websites that mean that there is no influence on the games by any outside variable, including the size of the potential payoff, play credit numbers, VIP cards, and some more.

How does the Random Number Generator operate in Digital Slots?

All the slot games featuring in online casinos like No Deposit Slots work with RNG technology. RNG is a microchip that generates numbers every time you spin, and the numbers generate even when the players are not playing. They generated hundreds of millions in number at a time.

No matter what slot game you are playing, classic, progressive jackpot or video slot, the RNG is responsible for positioning the reels' symbols. Each time you press the spin button or pull the lever, the video slot displays the creation of a new number location.

Technically, RNG is a microprocessor and known as the brain of video slots. No matter which level the player is playing on the machine, they cannot rig the RNG technology or influence the process.
