One of the most frequently asked questions by new online casino players is, “Are these games actually fair?” It’s a valid concern—especially in an environment where outcomes are generated by software rather than physical chance. That’s where RNGs, or Random Number Generators, come into play. These digital mechanisms are the backbone of fairness in online gaming, ensuring every spin, card draw, or dice roll is completely random and unbiased.
Trusted platforms like Co88 rely on certified RNG systems tested by independent agencies to maintain transparency and fairness. Unlike shady or unregulated sites that may use questionable software, Co88 makes player trust a top priority by using only RNGs that meet international standards. This commitment to fairness helps establish a safe gaming environment where players know they’re getting a genuine chance to win.
What Is an RNG?
A Random Number Generator is an algorithm—a complex piece of code—that continuously produces random sequences of numbers. These numbers are then translated into game outcomes. For example:
- In a slot game, the RNG determines which symbols appear on each reel.
- In a virtual blackjack game, the RNG shuffles and deals cards.
- In roulette, the RNG picks where the ball will land on the wheel.
Importantly, RNGs are constantly running, even when no one is playing. As soon as a player hits the “spin” or “deal” button, the system takes a random snapshot of whatever number the RNG has generated at that exact moment, which becomes the result.
Types of RNGs Used in Online Casinos
There are two main types of RNGs used in online gambling:
- Pseudo-Random Number Generators (PRNGs):
Most online casinos use PRNGs. These don’t require external input (like atmospheric data) to generate numbers. Instead, they use an initial seed value and complex formulas to produce a stream of results that appears completely random. When properly designed and tested, PRNGs are virtually indistinguishable from true randomness. - Hardware Random Number Generators (HRNGs):
Less common due to higher cost, HRNGs use physical phenomena (such as radioactive decay or electronic noise) to generate numbers. These are usually found in high-security environments rather than in typical online casinos.
Why RNGs Matter in Online Gambling
RNGs serve a crucial function in maintaining game integrity. Without them, outcomes could potentially be manipulated, making the gaming environment unfair or even fraudulent. RNGs eliminate patterns or predictability, ensuring every outcome is independent of the last.
This randomness is what gives players a fair shot at winning and preserves the house edge as designed—not through rigging, but through mathematical probabilities inherent to each game.
Fairness and Testing: Who Regulates RNGs?
To ensure fairness, reputable casinos have their RNGs tested and certified by third-party organizations. These include:
- eCOGRA (eCommerce Online Gaming Regulation and Assurance)
- iTech Labs
- GLI (Gaming Laboratories International)
- TST (Technical Systems Testing)
These organizations test games for fairness, verify that RNGs meet international standards, and issue certification seals to platforms that pass. Players can often find this information in the footer of the casino website or within the platform’s terms and conditions.
Platforms like Co88 proudly display their certifications and partner with verified software providers, giving players peace of mind.
How to Know You’re Playing on a Fair Site
Here are a few ways to identify if a casino uses a legitimate RNG system:
- Licensing and Regulation:
Make sure the casino is licensed by a recognized authority (such as MGA, UKGC, or Curacao). Licensing bodies require strict compliance with fairness regulations. - Third-Party Certification:
Look for RNG certification from independent testing agencies. - Transparent RTPs:
Reputable sites disclose the Return to Player (RTP) percentages for each game. An accurate and published RTP is a strong indicator of fairness. - Player Reviews and Reputation:
A trustworthy casino will have a good reputation in online forums and player communities.
Common Myths About RNGs
Despite their importance, RNGs are often misunderstood. Here are some myths that need debunking:
- Myth: The machine is “due” for a win.
RNGs make every spin or deal independent of previous outcomes. There is no memory—each result is pure chance. - Myth: You can “time” your win.
Since RNGs generate thousands of numbers per second, there’s no way to predict or time a win accurately. - Myth: Casinos can change the RNG to favor the house.
Certified platforms can’t change RNGs at will. Modifying RNG software without approval from regulators and third-party testers would result in license revocation.
Final Thoughts
Understanding RNGs is essential for anyone who wants to play online casino games with confidence. These algorithms are not just computer tricks—they are the foundation of fair, responsible gambling in the digital age. Without them, online casinos would lack credibility, and players would have no assurance that games are unbiased.
Fortunately, reputable platforms like Co88 go the extra mile to ensure that every game outcome is fair, random, and tested by third-party auditors. This kind of transparency builds trust, keeps gameplay honest, and allows you to focus on what really matters: enjoying the game.
