RNG is the abbreviation for Random Number Generator. This is a popular tool to get randomly generated numbers displayed with every spin on the slot machine. The aim is to ensure that every Player has the same chance of winning or hitting the Jackpot on every spin and that no one is disadvantaged or even cheated. The RNG technology thus also ensures that the average Payout ratio (RTP) is achieved.
Without a Random Number Generator, online casinos do not receive a license from authorities such as the Malta Gaming Authority (MGA). Reputable online casinos have the random number generator checked by independent third parties at regular intervals. For example, eCOGRA examines the reliability and independence of the random number generators used and awards the prestigious eCOGRA seal to selected providers.
Without a flawlessly functioning random number generator, fairness in the game cannot be guaranteed. To achieve this goal, the tool works, among other things, with mathematical equations and algorithms that cannot be influenced by humans. In general, two main types of RNG technologies can be distinguished: Pseudo and Hardware. While hardware RNGs are primarily used in land-based gaming venues, pseudo-random number generators are primarily found in online casinos. Pseudo-RNG is an algorithm that automatically programs long sequences of random numbers.
