How Slots Work: Random Number Generator and RTP
How Slots Work: Random Number Generator and RTP
1. Slot Basics
Modern slot machines, whether online or offline, are built on mathematics and algorithms. The mechanics are based on two key elements: the random number generator (RNG) and the return to player indicator (RTP). Together, they form the basis of the game's integrity and determine that the outcome of each spin is unpredictable.
2. Random Number Generator (RNG)
What are these:
Key features:
Myth: Slots can be "guessed" or "calculated."
Reality: The algorithm runs at millisecond intervals, making prediction or intervention impossible.
3. RTP: return to player
What are these:
Important points:
4. How RNG and RTP are related
The RNG is responsible for the randomness of a particular rotation.
RTP is built into the mathematical model of the slot and determines how often and how much winnings will fall.
Together, they form a balance between "entertainment" and "theoretical return."
5. Volatility and its role
In addition to RTP, each machine has a volatility indicator:
It is important for the player to take into account not only RTP, but also volatility, since it is this that affects the gaming experience and the distribution of winnings.
6. Why know mechanics
Exposing myths. Understanding how RNG and RTP work helps you not to believe in "winning hours" or "hot machines."
Game selection. The player can focus on RTP and volatility to find a slot for his style.
Strategy. Knowledge of mechanics allows you to build a game on real data, and not on illusions.
7. Result
Slots are pure math and randomness. RNG provides unpredictability for each rotation, and RTP sets the long-term mathematical return. No strategy or "secret method" will change these parameters. The only thing that remains under the control of the player is the size of the bets, the choice of the machine and the management of the bankroll.

2. Random Number Generator (RNG)
What are these:
- RNG is a program that generates a sequence of numbers every millisecond. When the player presses the "Spin" button, the algorithm fixes the current value and matches it with the result - a combination of symbols on the reels.
Key features:
- Complete independence of each spin. Previous results do not affect future ones.
- Lack of memory. The slot "doesn't know" how many consecutive wins or losses have come.
- Certification. RNG is independently reviewed by laboratories (e.g. eCOGRA, iTech Labs) to confirm integrity.
Myth: Slots can be "guessed" or "calculated."
Reality: The algorithm runs at millisecond intervals, making prediction or intervention impossible.
3. RTP: return to player
What are these:
- RTP (Return to Player) is a mathematical measure, expressed as a percentage, that reflects the theoretical share of bets returned to players in the long term. For example, an RTP of 96% means that on average out of 1000 AUD bets, the machine will return 960 AUD in the form of winnings.
Important points:
- RTP operates over a long distance. For several hundred or thousands of spins, the result can be very different from the declared percentage.
- Not equal to the probability of winning. RTP shows an average return, not a guaranteed win rate.
- Different slots are different RTPs. In classic automata, it can be lower, in modern video slots - higher (usually 95-98%).

5. Volatility and its role
In addition to RTP, each machine has a volatility indicator:
- Low - frequent but small winnings.
- High - rare, but large payments.
- The middle one is a compromise between the two extremes.
It is important for the player to take into account not only RTP, but also volatility, since it is this that affects the gaming experience and the distribution of winnings.
