How Free Spins Work
Scatter Symbol Triggers
The most common way to activate a free spin bonus is through scatter symbols. Landing the required number of scatter symbols anywhere on the reels typically triggers the feature.
Examples include:
- Three scatter symbols
- Four scatter symbols
- Five scatter symbols
The exact requirement depends on the game developer.
Bonus Activation
Once activated, players usually receive a predetermined number of free spins. During this feature, many games introduce additional mechanics such as:
- Wild symbols
- Multipliers
- Expanding reels
- Special animations
Each game determines its own bonus rules.
Retrigger Features
Some games include retrigger free spins, allowing players to earn additional free spins while the feature is already active.
For example:
1. Receive 10 free spins. 2. Land three scatter symbols again. 3. Earn another 10 free spins.
Not every slot game supports retriggers, but they are common in modern titles.
