When it comes to online gambling, fairness is everything. One of the most essential technologies that guarantees unbiased outcomes in digital casino games is the Random Number Generator (RNG). Trusted platforms like 68WIN use certified RNG systems to deliver fair and unpredictable results on every spin or hand
Understanding how RNG works can boost your confidence in online casino play and help you make more informed decisions.
What is an RNG?
An RNG is a software algorithm designed to produce completely random results. It’s used in online games such as:
- Slot machines
- Roulette
- Video poker
- Keno
- Virtual scratch cards
Every time you spin a reel or draw a card, the RNG is already working behind the scenes to generate a random result in milliseconds.
How Does It Work?
The RNG uses complex mathematical formulas and seed values to generate long sequences of numbers that don’t follow any pattern. These numbers are then converted into game results, such as:
- Which slot symbols appear on a reel
- Which card is dealt next in blackjack
- Where the roulette ball lands
Because this happens in real-time, the outcomes are independent of past results and can’t be predicted or manipulated.
Types of RNGs
- Pseudorandom Number Generator (PRNG)
This is the most common RNG used in online casinos. It uses an initial seed number and a set formula to produce results that appear random. - Hardware RNG (True RNG)
Unlike PRNGs, hardware RNGs use physical events (like electrical noise) to generate actual randomness. These are rarer in online platforms due to cost.
Why RNG Matters in Online Gambling
- Fairness: RNGs ensure that all players have the same chance of winning.
- Unpredictability: No one, not even the casino, can know or control the outcome in advance.
- Game Integrity: It prevents fraudulent behavior and maintains trust.
- Regulatory Compliance: Licensed casinos must undergo regular audits to confirm their RNGs are working correctly.
How RNGs Are Tested
Reputable casinos work with third-party testing agencies to audit their RNG systems. These agencies include:
- eCOGRA
- iTech Labs
- Gaming Laboratories International (GLI)
- TST (Technical Systems Testing)
They run thousands of simulations to check if the results fall within expected statistical ranges. Once passed, the casino earns certification, which is usually displayed on its homepage or in the footer.
Tips to Ensure You’re Playing Fair Games
- Choose licensed casinos: Look for platforms regulated by trusted gaming authorities
- Verify RNG certification: Check if the casino displays audit badges or certificates
- Avoid shady platforms: If you’re unsure about a site’s integrity, don’t deposit money
- Play demo versions: Try out free versions to see if outcomes feel consistent and fair
Common Myths About RNGs
- Myth: RNGs are rigged.
Reality: Licensed casinos must use certified RNGs and face penalties for manipulation. - Myth: You can beat the RNG with a system.
Reality: RNGs are designed to be unpredictable. No betting system can alter the odds. - Myth: Games have “hot” or “cold” cycles.
Reality: Each spin or hand is independent. There’s no memory of previous outcomes.
Conclusion
RNGs are the cornerstone of fair play in the online gambling world. They ensure that every spin, card, or outcome is purely chance-based, providing players with a trustworthy and level playing field. Knowing how RNGs work—and verifying the casinos that use them—can give you peace of mind as you enjoy your gaming experience.
