Modern online slots come with a host of features beyond the basics of spinning the reels. Wilds help you form winning combinations, scatters give free spins, and multipliers boost your winnings. Some games also include bonus rounds that offer even more rewards.
These features don’t work identically in every slot. Understanding their basic functions makes it easier to follow the action and recognize how winnings are calculated.
What Are Slot Features?
Slot features are mechanics that affect how a game works. Some change how winning combinations form, while others add extra spins or bonus rounds. They can appear randomly during ordinary gameplay or when you meet certain conditions.
Before you play slots online, it’s worth checking the game’s paytable. This explains which features are available, how they’re triggered, and what they can pay. Familiar symbols can behave differently across games, so it’s important to understand each game’s rules.
Wild Symbols
Wilds are probably the most common symbols when playing slots. They substitute for other symbols, helping you make winning combinations. For example, you could have two matching symbols, and a wild could act as the third to create a payout.
However, wilds generally cannot replace scatters or certain bonus symbols. Some games also include variations that provide additional functions.
Different Types of Wilds
- Expanding wilds: Spread across an entire reel or specified area.
- Sticky wilds: Remain in position for several spins.
- Walking wilds: Move across the reels between spins.
- Multiplier wilds: Increase qualifying winning combinations.
These variations don’t appear in every game. Some appear during ordinary spins, while others are restricted to bonus rounds. Their exact behavior depends on the individual slot.
Scatter Symbols
Scatters are different from ordinary paying symbols. They usually count wherever they appear on the reels, without needing to land on a certain payline. Commonly, they trigger free spins or other bonus features.
For example, landing three scatters on a single spin might activate a free-spin round. Some games require four or more, while others award additional spins when extra scatters appear. The number required depends on the game’s rules.
Scatters can also pay out directly in certain slots. However, some games use them exclusively to trigger bonus features, meaning they don’t necessarily produce an immediate cash win.
Free Spins
Free spins are what the name suggests: they let you spin the reels again without placing another wager. They often trigger on scatters, though some games use other triggers. The spins will often use the qualifying stake from the original wager.
For example, a game might award ten free spins after three scatters appear. During those spins, players can receive standard payouts, special symbols, or extra features. Any winnings are calculated according to the game’s rules.
Retriggering Free Spins
Some slots allow players to win additional free spins while an existing feature is running. This is called retriggering and usually requires another qualifying symbol combination. A game might award five additional spins if three scatters appear during the bonus.
Multipliers
Multipliers increase the value of qualifying wins by a set amount. You’ll usually see them displayed as numbers such as 2x, 3x or 5x. For example, a £2 winning combination with a 3x multiplier would pay £6.
Some games apply multipliers to individual combinations, while others multiply the total spin winnings. They can appear during ordinary gameplay or be restricted to bonus features.
Common Multiplier Features
- Wild multipliers: Increase payouts when a wild forms part of a winning combination.
- Random multipliers: Activate according to the game’s rules.
- Free-spin multipliers: Increase qualifying winnings during bonus spins.
- Progressive multipliers: Grow when specified conditions are met.
Some slots allow multiple multipliers to apply to the same win. Depending on the game, these values might be added together or multiplied. The paytable should explain how the final payout is calculated.
Other Common Slot Features
Alongside wilds, scatters and multipliers, many slots include mechanics that change how the reels behave. Cascading reels are a common example. These remove symbols involved in winning combinations and replace them with new ones. This can create additional wins without requiring another paid spin.
Some games continue the cascades until no further winning combinations appear. Others introduce increasing multipliers after successful cascades, which can increase subsequent payouts.
Expanding Symbols
Expanding symbols cover additional reel positions when specific conditions are met. This can create more opportunities for winning combinations. Unlike expanding wilds, they don’t necessarily substitute for other symbols.
Bonus Rounds
Bonus rounds add gameplay or rewards outside the base game. They might involve choosing concealed prizes, spinning a special wheel, or playing a modified version of the main game. Scatters, bonus symbols, or specific combinations commonly trigger these features.
Rewards may include cash prizes, free spins, or multipliers. Although bonus rounds can pay out more than ordinary spins, their results remain uncertain. Triggering a feature doesn’t guarantee a substantial win.
What Is a Bonus Buy?
A bonus buy lets players pay a set amount to activate a bonus feature immediately. This removes the need to wait for the feature to appear during ordinary spins. The price is usually calculated as a multiple of the selected stake.
For example, a game might charge 100 times the selected stake to enter its free-spin round. At a £0.20 stake, that would cost £20, regardless of how much the feature eventually pays.
Understanding Slot Features
Wilds help complete combinations, scatters often trigger bonuses, free spins provide additional chances to win, and multipliers increase qualifying payouts. Bonus rounds add more variety, but their rules differ between games. Checking the paytable remains the simplest way to understand how each feature operates.
No slot feature guarantees a profit or removes the possibility of losing money. Players should understand the rules before betting and keep their spending within affordable limits.
