What is RNG (Random Number Generator)?
A Random Number Generator (RNG) is a crucial technology used in the iGaming industry to ensure fairness and unpredictability in games. It generates random outcomes for games like online slots, poker, and other casino games, simulating the randomness you would experience in real-life gaming environments. RNGs are designed to produce sequences of numbers or symbols that cannot be predicted, ensuring each spin, card deal, or dice roll is completely independent from the previous one.
How does RNG work?
There are two main types of Random Number Generators: software-based (pseudo-random) and hardware-based (true random). Both types aim to create random outcomes, but they work in different ways.
Software RNG (Pseudo-Random Number Generator - PRNG)
A software-based RNG, or PRNG, uses algorithms to generate sequences of numbers that appear random. PRNGs rely on an initial seed value, which is then processed through mathematical formulas to produce a stream of numbers. Although PRNGs are technically deterministic, they can still create outcomes that are effectively unpredictable for gaming purposes. PRNGs are commonly used in online games, as they are faster and easier to implement, providing reliable results without the need for physical hardware.
Hardware RNG (True Random Number Generator - TRNG)
A hardware-based RNG, or TRNG, generates random numbers from physical processes, such as electrical noise or radioactive decay. Unlike PRNGs, TRNGs rely on naturally occurring random events, making their results truly unpredictable. TRNGs are more commonly used in highly regulated environments or for security applications where true randomness is critical. While less common in iGaming, they are still used in some cases to enhance trust in game fairness.
What is RNG used for?
RNG is essential for ensuring the fairness and transparency of online casino games. It is used to shuffle cards in digital poker, determine the outcome of a spin in slot games, or roll dice in table games. Without RNGs, it would be impossible to create a fair and impartial gaming experience for players, as outcomes could otherwise be manipulated or predicted.
Examples of RNG in use.
- Online slots: RNG determines the symbols that appear on the reels during each spin, ensuring that every result is random and not influenced by previous spins.
- Digital poker: The RNG shuffles the deck and deals cards to players, ensuring that the game cannot be rigged and that every player has a fair chance.
- Roulette: RNG generates the number that the ball lands on in virtual roulette games, replicating the randomness of a physical roulette wheel.
Benefits of using RNG.
- Fairness: RNG ensures that the outcomes are unbiased and cannot be influenced by players, operators, or external factors.
- Compliance: Regulatory bodies often require certified RNGs to ensure fair play, making them a legal requirement for licensed casinos.
- Security: RNGs protect the integrity of games by preventing any attempts to predict or alter outcomes, ensuring players can trust the gaming platform.
Tips for using RNGs.
- Certification: Always check if the casino you are playing at uses RNGs certified by independent testing labs such as eCOGRA or GLI. This ensures the RNG meets industry standards.
- Understand RTP (Return to Player): While RNGs are random, games still have predefined payout percentages (RTP). Understanding this helps set realistic expectations for long-term play.
- Responsible gaming: Remember that RNGs guarantee randomness but not guaranteed wins. Always play responsibly and within your limits.
By using RNG technology, the iGaming industry ensures a trustworthy and enjoyable gaming experience for all players.
