A random number generator, often referred to as RNG, is a core component of how pokies operate. This page provides an informational explanation of the role RNG systems play in generating outcomes in slot-style games within the Australian gaming industry.
What a random number generator is
An RNG is a software-based system designed to continuously generate sequences of numbers. These numbers are produced regardless of whether a game is being played, running constantly in the background.
When a spin is initiated, the game reads the current output of the RNG and uses it to determine the result of that spin.
How RNG determines outcomes
The RNG output is mapped to specific game elements based on predefined rules created during game development. These rules define how numbers correspond to symbols, reels, or other outcome components.
Key characteristics of RNG-based outcomes:
- Each spin is generated independently
- Previous results do not influence future outcomes
- Outcomes are determined instantly at spin initiation
- Visual animations reflect a result already calculated
RNG and visual presentation
Reel movements, symbol animations, and sound effects are visual representations designed to display the outcome to the player. They do not influence the result itself.
The sequence is always:
- RNG generates a result
- The game logic interprets the result
- Visual elements display the outcome
Role of RNG in game design
RNG systems operate within strict technical parameters defined during the design of a pokie. These parameters work together with other elements such as paytables, symbol frequencies, and feature triggers.
RNG interacts with:
- Symbol probability distributions
- Payline or win-structure rules
- Bonus and feature activation logic
- RTP and volatility configuration
Testing and certification
RNG systems are typically subject to testing and certification by independent laboratories as part of regulatory requirements. These tests are intended to confirm that outcomes are generated fairly and without predictable patterns.
Certification processes usually focus on:
- Randomness and unpredictability
- Statistical distribution of outcomes
- Compliance with technical standards
- Absence of external manipulation
