1. Definition
An “Expanding Wild” is a special wild symbol in slot games that, upon appearing, expands vertically (and occasionally horizontally) to cover an entire reel. This feature significantly increases the chance of forming winning combinations during a spin.
2. Background and Mechanics
Expanding Wilds are commonly used in modern video slots to enhance gameplay and add visual excitement. Key mechanics include:
- A single wild symbol expands to fill the full height of a reel
- Expansion may be automatic or conditional (e.g., only during wins or bonus rounds)
- Multiple expanding wilds appearing on different reels can dramatically boost potential payouts
3. Examples and Usage
- In Book of Dead, certain symbols become expanding wilds during free spins, turning full reels into wilds
- Starburst features wilds that expand on the middle reels and trigger respins
- These features are often paired with visual and sound effects to heighten excitement
4. Differences from Related Terms
- Regular wilds substitute one symbol per space; Expanding Wilds take over an entire reel
- Sticky Wilds remain across multiple spins, while Expanding Wilds are typically limited to one spin
- Walking Wilds move across reels but do not expand
5. Tips and Considerations
- Whether wilds always expand or only under certain conditions depends on the game
- Their behavior may differ between base game and bonus features
- Landing multiple expanding wilds at once can lead to massive wins—placement is crucial
