Free spins are a common bonus feature used in many pokies. This page provides an informational explanation of how free spins work and how they are integrated into the overall game structure, without encouraging gambling activity.
What free spins are
Free spins are a bonus feature that allows a predefined number of spins to be played under special conditions. These spins are awarded by the game according to fixed rules and do not require manual activation beyond meeting the trigger conditions.
Free spins are designed to:
- Add variation to base gameplay
- Introduce alternative rule sets temporarily
- Showcase additional game features
- Operate as part of the overall game model
How free spins are triggered
Free spins are typically triggered when specific conditions defined in the game logic are met. These conditions are established during development and remain constant.
Common trigger methods include:
- Specific symbol combinations on the reels
- Scatter symbols appearing in certain positions
- Activation through a bonus feature
- Randomised triggers defined by the game model
The triggering process does not bypass the random outcome system.
How free spins operate
Once activated, free spins run under predefined bonus rules. These rules may differ from base gameplay but are fully specified in advance as part of the game design.
During free spins, a game may apply:
- Multipliers to eligible outcomes
- Expanding or special symbols
- Modified reel layouts
- Additional feature interactions
Despite these changes, each spin is still generated independently using the same random number generation process.
Free spins and game mathematics
Free spins are incorporated into the mathematical model of a pokie. Their frequency, outcome distribution, and contribution to overall game behaviour are calculated during development.
Important characteristics:
- Free spin rules are fixed
- Probability structures remain unchanged
- Outcomes are not influenced by player actions
- Behaviour is consistent across sessions
Free spins do not introduce unpredictability beyond what is already defined in the game model.
