How to Choose the Best RNG for Fair and Transparent Slot Games?
The RNG in slot machines is crucial to maintain fairness and transparency of any casino game, which is required to maintain players’ trust and satisfaction. Let’s understand the best practices of implementing slot machine random number generators (RNGs) and how to choose the best slot game.
What is a Slot Machine Random Number Generator?
The slot machine RNG is a mathematical algorithm that continuously generates combinations of numbers and symbols, which makes each spin random and independent of the other. These combinations determine the outcome, which appears on the paylines after you press the ‘spin’ button.
How does RNG work in slots? Modern RNG slots use pseudo-random Number Generators (PRNGs) that work on complex mathematical formulas to determine the result. PRNGs are not only random but also impossible to predict due to their complex algorithms.
Best Practices for Implementation of RNG in Slot Machines

Choosing the Right RNG Type
The first basic step is choosing the right slot machine RNG for your game. There are mainly two types of RNGs:
- True Random Number Generators(TRNGs): They use a physical process to create random combinations through machine noise. TRNGs are truly unpredictable and completely random.
- Pseudo Random Number Generators(PRNGs): This uses slot machine RNG algorithms that generate a random number sequence that is approximately random. While they are not completely random but most casinos uses PRNG for its speed and efficiency. This is a more popular choice for RNG fair play games as it is easy to implement into the slot machines.

Use of Proven Slot Machine RNG Algorithm
As a casino game developer, one should always use the slot machine random number generator, which is certified and mostly trusted in the industry. Some trusted and proven RNG algorithms include:
- Mersenne Twister
- Xorshift
- Crypto-Secure RNGs

Auditing and Testing of Online Slot RNG System
Continuous auditing and testing of RNG software for slots is crucial to avoid any major downtime. Always start by running tests on the workings of the RNG algorithm and ensuring that the results are truly random. You can also consider third-party testing to maintain the integrity of your slot game.

Regulatory Compliance
The regulatory requirements differ from jurisdiction to jurisdiction. Make sure to follow the local laws and regulations where you are offering your casino game services. Ensure that your slot machine's random number generator complies with the legal standards. This includes certification requirements, RNG audits, and documentation.

Being Transparent with players
Communication is the key when it comes to running a casino game business. Provide clear information about the RNG system used in your slot machines to maintain the trust of your players.

Licensing of Slot Games
First and foremost, it is vital to ensure that the slot machine has a certified RNG provider. Some reputable authorities offer certified RNG systems, and your slot game provider should be able to provide them. A license ensures that the game is safe and provides safety of your data.

Slot Game Provider
A slot game provider such as GammaStack ensures high-quality gaming and maintains fairness standards. The choice of a provider is a crucial step to ensure your money is not misused and you get reliable playing conditions. The company’s reputation is also a major factor to look upto when choosing a slot machine provider.

Return to Player (RTP)
RTP (Return to Player) is calculated as the percentage of the total bets the slot machine is designed to return to players in the long run. The RTP% depends on your slot machine strategies. It is always recommended to go for a higher RTP slot, which has an RTP% higher than 95%. However, high RTP does not mean your winnings will be increased; it simply offers more chances of long-term success.

Game Volatility Rates
Volatility is measured by the frequency and size of the winning combinations. They are of three types: high volatility offers larger wins but less frequently, low volatility offers smaller wins but more frequently, and medium volatility offers a match of both. Choose the one best suited for your gameplay.

Bonus Features
Modern slot machines have many different types of bonus features that make the game more interactive and full of excitement. Bonus features such as free spins, multipliers, wilds, etc, increase the possibility of wins for players, which increases the engagement level.

Reviews and Ratings
Player reviews & ratings on slot machine games can provide valuable information about the game. Check for reviews before proceeding with buying the game. This will help you avoid playing unreliable games with low/no payouts.

Mobile Compatibility and Usability
Mobile gaming has been on the rise now than ever before. Always go for slot game providers offering mobile versions of games that can be played from anywhere.
