Slot Bonus Features Explained: Wilds, Scatters, Multipliers
A complete guide to slot bonus features including wilds, scatters, multipliers, free spins, and more. Understand every feature you will encounter in modern slots.
Understanding Slot Bonus Features
Modern online slots are packed with special features that go far beyond simple spinning reels. Knowing what each feature does helps you appreciate the games more and make informed choices when browsing slots.
Wild Symbols
What They Do
Wild symbols substitute for other symbols to complete winning combinations, similar to a joker in card games. If you have two matching symbols and a wild on the same payline, the wild acts as a third matching symbol.
Types of Wilds
Standard Wilds — substitute for all symbols except scatters and bonus triggers. Expanding Wilds — grow to cover an entire reel when they land, creating more winning possibilities. Sticky Wilds — remain in place for multiple spins, common during free spins rounds. Walking Wilds — move one position (usually left) each spin until they walk off the grid. Multiplier Wilds — substitute for symbols AND multiply the win by 2x, 3x, or more. Stacked Wilds — appear as tall stacks covering multiple positions on a reel.Scatter Symbols
What They Do
Scatters pay regardless of payline position — they just need to appear anywhere on the reels. They are also the most common trigger for bonus features.
Common Scatter Functions
- Trigger free spins — usually 3+ scatters needed (see our free spins guide)
- Award instant payouts — some scatters pay a multiple of your total bet
- Activate bonus games — interactive pick-and-click rounds or wheel spins
Multipliers
What They Do
Multipliers increase your wins by a specified factor. A 3x multiplier turns a 10-coin win into 30 coins.
Where Multipliers Appear
Base Game Multipliers — random multipliers applied to regular wins, as seen in Gates of Olympus. Free Spins Multipliers — a fixed multiplier applied to all wins during the bonus round (common: 2x or 3x). Progressive Multipliers — increase with each consecutive cascade/tumble win. Start at 1x and grow throughout a sequence. Multiplier Symbols — special symbols carrying multiplier values, like the bombs in Sweet Bonanza.Free Spins Features
Free spins are the centerpiece bonus feature in most slots. They award a set number of spins at no cost, often with enhanced mechanics.
Common Enhancements
- Extra wild symbols added to the reels
- Multipliers on all wins
- Expanding or transforming symbols
- Upgraded symbol values
- Retrigger potential for additional spins
Cascading/Tumble Wins
After a win, the winning symbols are removed and new symbols drop in. This continues until no new wins form. Each cascade can also increase a multiplier in some games.
Popular in Pragmatic Play titles like Gates of Olympus and Sweet Bonanza.
Bonus Buy / Feature Buy
Some slots let you purchase direct access to the bonus round for a fixed cost (usually 50-100x your bet). This skips the base game entirely.
Pros: Instant bonus access, no waiting Cons: Premium cost, no guarantee of a good bonus roundGamble Feature
After any win, some slots offer a gamble option — typically guessing a card color (double) or suit (quadruple). Winning doubles your payout; losing forfeits it entirely. Common in Novomatic classics.
Hold and Spin / Respins
A feature where certain symbols (usually money symbols) lock in place while the remaining positions respin. Additional matching symbols that land also lock. The round ends when no new symbols land or all positions are filled.
Pick-and-Click Bonuses
Interactive rounds where you select items on screen to reveal prizes. Each selection awards coins, multipliers, or other rewards. Popular in Betsoft 3D slots.
