What Is a Bonus Buy in Slots? How Feature Buys Work
Learn what a bonus buy is in online slots, how feature buys work, how they differ from triggering bonuses naturally, and what to check before using one.

What Is a Bonus Buy in Slots? How Feature Buys Work
A bonus buy is a slot feature that lets you pay a specified amount to enter a bonus round directly instead of waiting for it to trigger during normal gameplay.
Bonus buys are also commonly called feature buys.
They are popular in modern online slots because they give players immediate access to features such as free spins, enhanced multipliers or other bonus mechanics.
If you are new to slots, start with our beginner's guide to online slots.
What Is a Bonus Buy?
Normally, a slot bonus is triggered by landing a required combination of symbols or completing a specific game condition.
A bonus buy changes that process.
Instead of waiting for the feature to appear naturally, the player pays a set price and the slot starts the bonus directly.
The exact price and feature depend on the individual game.
How Does a Bonus Buy Work?
A typical bonus-buy process looks like this:
Open a slot that supports bonus buys.
Select the bonus or feature-buy option.
Review the cost.
Confirm the purchase.
The bonus feature begins according to the game's rules.
The cost is usually linked to your selected bet size.
How Much Does a Bonus Buy Cost?
Bonus-buy prices are often shown as a multiple of your bet.
For example, a game might price a feature at:
50x your bet
75x your bet
100x your bet
200x your bet
If the bonus costs 100x your bet:
| Bet Size | Bonus Cost |
|---|---|
| $0.20 | $20 |
| $0.50 | $50 |
| $1 | $100 |
This is only an example. Each slot sets its own feature-buy price.
What Does a Bonus Buy Give You?
The purchased feature depends on the game.
Common bonus buys include:
Enhanced free-spin rounds
Higher starting multipliers
Special wild features
Extra reels or symbols
Alternative bonus modes
Some slots offer several different bonus buys at different prices.
Bonus Buy vs Triggering the Bonus Naturally
| Feature | Natural Trigger | Bonus Buy |
|---|---|---|
| How you enter | Trigger the required symbols or condition. | Pay a specified amount directly. |
| Time to access | May take many spins. | Immediate after purchase. |
| Extra cost | No separate feature-buy payment. | Yes, often a large multiple of the base bet. |
Does Buying a Bonus Guarantee a Profit?
No.
Paying for a bonus only gives you access to the feature.
It does not guarantee that the value of the resulting payout will exceed the purchase price.
A purchased bonus can return:
Less than the amount paid
Roughly the same amount
More than the amount paid
A much larger payout
The result still depends on the game's underlying mathematics.
Are Bonus Buys High Risk?
They can involve significantly larger amounts per decision than normal spins.
For example, if your base bet is $1 and the feature costs 100x, one bonus purchase costs $100.
That means a series of feature buys can reduce a balance much faster than normal $1 spins.
For this reason, it is especially important to understand the total cost before confirming the purchase.
Do Bonus Buys Change RTP?
Some slots may use a different theoretical RTP for the bonus-buy mode compared with the normal base game.
This depends on the provider and game configuration.
If the game displays separate RTP information for feature buys, check the specific figure shown inside the slot.
You can learn more about theoretical return in our guide to RTP in slots.
Do Bonus Buys Change Volatility?
Using a bonus buy can expose you immediately to a feature where more of the game's payout potential may be concentrated.
This can create much larger short-term swings in your balance.
However, the underlying slot volatility is determined by the game's full mathematical model.
What Is an Enhanced Bonus Buy?
Some slots offer more than one feature-buy option.
For example, a game may offer:
A standard free-spin feature
A more expensive enhanced free-spin feature
A bonus with guaranteed special symbols
A feature with a higher starting multiplier
The more expensive option may change the bonus mechanics, but it still does not guarantee a profitable result.
Do Bonus Buys Include Multipliers?
Many bonus features include slot multipliers.
These may:
Start at a fixed value
Increase after consecutive wins
Appear on special symbols
Build throughout the feature
The rules differ significantly between games.
Can a Bonus Buy Trigger Wilds and Scatters?
Bonus rounds often use wild and scatter symbols differently from the base game.
For example, a free-spin feature may include:
Sticky wilds
Multiplier wilds
Expanding wilds
Scatter retriggers
These mechanics form part of the value and risk of the purchased feature.
Are Bonus Buys Available on Every Slot?
No.
Many slots do not include bonus buys at all.
Availability can also depend on:
The game provider
The specific slot
The game version
The player's jurisdiction
If a feature buy is available, it will normally appear directly inside the game interface.
Why Are Bonus Buys Restricted in Some Places?
Bonus-buy availability can vary because gambling rules differ between jurisdictions.
Some markets restrict or do not permit certain feature-buy mechanics.
This is why the same slot may offer a bonus-buy button to one player while another version of the game does not.
Can You Predict the Result of a Bonus Buy?
No reliable method can predict what a purchased bonus will return.
Previous bonus results do not guarantee what will happen in the next feature.
A poor previous bonus does not mean the next one is due to pay more, and a large previous win does not prevent another large result.
What Should You Check Before Buying a Bonus?
Before confirming a feature buy, check:
The total purchase price
Your current bet size
Which bonus feature you are buying
The number of free spins or feature conditions
Any multiplier mechanics
The game's RTP where displayed
The game's volatility
The maximum possible win
Most importantly, make sure the purchase amount fits within the gambling budget you have already set.

Know the Cost Before You Buy
Bonus buys give players immediate access to some of the most feature-heavy parts of modern online slots.
But immediate access comes with a clearly defined price, often equal to many normal spins at once.
Before using one, understand the feature, check the cost and remember that purchasing a bonus does not guarantee a profitable result.
