Random Number Generators Are A Crucial Portion Of Online Casino Software
Casino games are acknowledged as games of chance which even if you win or lose is fully decided by a randomizing element. In land based casinos, it could be the turn of a card, the roll of a dice, or the spin of a roulette wheel.
For online casinos, the biggest challenge that they have is to simulate the exact experience as a physical casino when playing as much as possible while ensuring unbiased outcomes. Taking into account the fact that there are no real cards being dealt, no real dice being rolled, and no real roulette wheels being spun, the outcome of these actions have to be reproduced artificially by software. This is done through the leverage of random number generators (RNGs).
1. What are RNGs?
RNGs are the modern application of randomness devices that have existed since ancient times such as dice, shuffled cards, flipping coins and even drawing straws. In modern computing, RNGs are implemented through programming based on deterministic algorithms. Its goal is to make sure that, when you send the slots reels spinning, they stop on a random position.
Essentially, RNG technology is the technological key that makes online gambling possible. Assuming they’re not rigged, RNGs are the key to getting a fair online casino – whether it’s slots, blackjack, or any other game of chance. It’s also worth mentioning that RNGs are also used in physical casinos. Video slot machines use them to determine which symbols appear on each spin, and video poker machines use them to determine which cards are dealt.
However, modern random numbers are pseudo-random and are generated in a predictable fashion using a mathematical formula. To the human eye, the numbers may appear to be randomly generated, but to a machine, it is not. With just a seed number and a dependence on an algorithm, random numbers will remain vulnerable to hacking.
2. How are RNGs used by Online Casinos?
Online casinos work by using software that imitates the actions that take place in a live casino and then displays the outcomes virtually on your computer screen using graphics. The outcomes displayed have to be produced randomly in order to reflect the randomness that is inherent in all casino games. This is where the use of RNGs comes in.
Any time that the software needs to reproduce a random outcome, it communicates with the RNG. Whatever number has been generated by the RNG at that precise moment is then fed into the software. Each possible number is related to a possible outcome, and the software displays the relevant outcome accordingly.
For example, imagine you are playing blackjack and decide to hit. In a physical casino, your next card will simply be dealt from the top of the deck. In an online casino, though, there is no real deck to deal cards from. The casino software will, therefore, call upon the RNG to provide it with a random number. The number the RNG provides will determine which card you are to receive within the similar parameters of a physical casino.
3. How can we check if RNGs are Fair?
There are special outsourcing companies which license casinos. They test casino equipment, including RNGs. Game operators who use the algorithm of pseudo-random numbers claim that saving the reputation and players’ trust is important for them, therefore it is unprofitable to cheat. The second argument in favor of such casinos is that the combination of numbers generated by the algorithm is practically impossible to anticipate.
Thousand-digit numbers or, for example, Pi, consisting of 5 trillion digits after the comma, are used as the starting point of the algorithm and the final number is generated by means of difficult sequences of mathematical actions. The algorithm generates a combination before the player presses the “Start” button and the reels or the roulette wheel start to move.
Checking the working principle of an RNG is possible only after examining an online casino’s server — this is what the companies that license casinos to do. It is clear to everybody that this scheme of checking online casinos cannot be considered completely reliable.
One of the solutions to this problem is offered by blockchain casinos. The outcome is generated by means of an algorithm of random numbers based on the hash of blocks in a blockchain. On the one hand, it allows any network participant to see any given transaction and be convinced that the number has been generated fairly.
GINAR is an innovative decentralized Random Number Generator (dRNG) based on Blockchain technology. It promises to generate true, fair and transparent random numbers at an impressive speed and volume. It resides on the Ethereum blockchain in the form of a smart contract. Anyone with an Ethereum account can take part in the generation process, hence fairness is guaranteed. The core idea is to allow participants to give their contribution (i.e. party’s secret) to form the final randomness ensuring the verifiability and fairness, but not the problem of randomness as a whole as participants do need to have access beforehand to an RNG they consider secure.
