Fairness is a cornerstone of any reputable online casino, and technology plays a vital role in maintaining trust between players and operators. One of the most important technologies used is the Random Number Generator (RNG), which ensures that game outcomes are unpredictable and unbiased. Trusted platforms like 77Loc utilize certified RNG systems to guarantee fair play for all users.
What Is a Random Number Generator?
An RNG is a computer algorithm designed to produce sequences of numbers that lack any predictable pattern. In online casinos, RNGs determine the results of games such as slots, roulette, blackjack, and poker by generating random outcomes each time a game action occurs.
This randomness replicates the unpredictability of real-world gambling devices like slot machines or card shuffles.
Types of RNGs
- Pseudo-Random Number Generators (PRNGs): Most online casinos use PRNGs, which use mathematical formulas to produce sequences that appear random. Although deterministic, these sequences are complex enough to be considered random for practical purposes.
- True Random Number Generators (TRNGs): Less common in online casinos, TRNGs use external physical processes like atmospheric noise to generate randomness. These are typically used in specialized applications.
Certification and Testing of RNGs
For players to trust that an online casino is fair, RNGs must be tested and certified by independent third-party organizations such as eCOGRA, iTech Labs, or GLI.
These auditors:
- Analyze RNG algorithms for statistical randomness.
- Ensure games comply with regulatory standards.
- Test payouts and fairness over millions of simulated game rounds.
Reputable casinos like 77Loc proudly display certifications to reassure players.
How RNGs Affect Different Games
- Slots: RNGs determine the symbols that appear on reels for every spin.
- Roulette: RNGs generate the virtual ball’s landing number.
- Card Games: RNGs shuffle and deal cards in blackjack or poker.
- Other Games: RNGs determine outcomes in keno, scratch cards, and more.
Because of RNGs, each game outcome is independent, meaning past results don’t influence future spins or hands.
Why RNGs Are Important
- Fairness: Prevents manipulation or cheating by casino operators.
- Transparency: Ensures all players have equal chances.
- Regulation: Compliance with laws and licensing requirements.
- Player Confidence: Boosts trust and encourages ongoing play.
Common Misconceptions
- RNGs don’t “warm up” or change behavior over time.
- No strategy can predict or influence RNG outcomes.
- Each spin or hand is independent; there is no memory of previous results.
Understanding these points helps players avoid myths and gamble responsibly.
How to Identify Reliable Casinos Using RNGs
- Look for licensing from recognized authorities.
- Check for independent testing certificates.
