Our Detailed Guide on Bonus Buy Slots

Bonus Buy slots can also be known as “Buy Feature slots” or even “Buy Free Spins slots” but they all revolve around the same concept, giving players the opportunity to unlock a slot’s bonus feature instantly rather than waiting a period of time for it to trigger during regular gameplay. This slot type has been described as revolutionary in the slot world and has opened up so many opportunities for developers to enhance gameplay. The bonus round is seen as the most rewarding, most enjoyed and best part of a slot game, fans have said that the option to skip the base game and enter the feature round instanlty is insane!

Depending on how the developer has set the games mechanics up, titles can include things such as free spins rounds, bonus games, respin features, multiplier boosts, expanding wilds, sticky symbols or other premium mechanics designed solely to increase winning potential for the player.

For the past decade Bonus Buy Slots have sky rocketed to become one of the most rewarding slot categories at Non UK Casinos, this has lead to huge numbers of players seeking casinos offering the latest and best bonus buy slots not only in the UK but worldwide. Many players prefer this style of gameplay due to the fact it provides much faster access to a higher level of volatility, features and eliminates the uncertainty of waiting for bonus symbols to land naturally.

One of the top reasons Bonus Buy games remain so popular is that the slot’s biggest prizes are often linked to the bonus feature itself. In many modern game releases, the maximum win potential, highest multipliers and most lucrative combinations can only be achieved within the free spins or special bonus rounds.

How Much Do Bonus Buy Slots Cost in the UK?

Bonus Buy slots allow players to pay a fixed price to unlock a game’s bonus feature instantly. Instead of waiting for scatter symbols or bonus icons to land naturally, players can jump straight into free spins, feature rounds, respins or premium bonus modes.

The cost of a Bonus Buy is normally calculated as a multiple of your bet, for example if a feature costs 100x and your stake is £1 the bonus purchase will cost £100. After reviewing thousands of bonus buy slots and casinos offering them most Bonus Buy Features range from 50x to 200x your bet, we have come across some games that offer a cheaper entry level option and in some extreme cases a premium Super Buy costing 500x or more!

Bonus Buy Cost Breakdown

Bonus Buy Type	Typical Cost	Risk Level	Best For
Low Tier Buy	20x – 75x stake	Low-Medium	Smaller bankrolls and casual players
Standard Buy	80x – 120x stake	Medium-High	Balanced risk and reward
Premium Buy	150x – 300x stake	High	Players chasing stronger bonus features
Super Bonus Buy	300x – 500x+ stake	Very High	High-volatility players seeking max win potential

Lower Tier Bonus Buys

Lower costing Bonus Buys are usually the most accessible option normally priced between 20x and 75x your bet. These features are ideal for players who want to experience bonus gameplay without committing to a large upfront cost. They commonly include:

• Basic free spins rounds
• Lower volatility gameplay
• Smaller but more frequent returns
• Reduced feature costs
• More balanced session control

While these features may not unlock the biggest win potential, they can be a better fit for players who prefer longer sessions and steadier gameplay.

Standard Bonus Buys

Standard Bonus Buys are the most common option found in modern slots and usually cost around 80x to 120x the stake. This is often seen as the middle ground between price, volatility and payout potential. These features may include:

• Enhanced free spins
• Multipliers
• Extra bonus symbols
• Respins or retriggers
• Medium to high volatility mechanics

For many players, standard Bonus Buys offer the best balance between cost and entertainment value.

Premium & Super Bonus Buys

Premium Bonus Buys are designed for players who want access to the strongest version of a game’s bonus round. These usually cost between 150x and 500x+ the stake. Higher level features may include:

• Guaranteed multipliers
• More free spins
• Stronger wild features
• Upgraded bonus mechanics
• Higher RTP bonus modes
• Access to the game’s biggest win potential

These features can be exciting, but they are also much more volatile. Results can vary heavily, so bankroll management is essential.

Bonus Buy Cost Example

Stake	50x Buy	100x Buy	250x Buy	500x Buy
£0.20	£10	£20	£50	£100
£0.50	£25	£50	£125	£250
£1	£50	£100	£250	£500
£2	£100	£200	£500	£1,000

How to Find the Best Bonus Buy Slots

Choosing the right Bonus Buy slot is not just about picking the game with the biggest advertised max win. The best option depends on your budget, preferred volatility, RTP, feature type and how much risk you are comfortable taking.

Before buying any bonus feature, think about how much you are willing to spend during a session. A lower costing Bonus Buy may be better for smaller budgets, while premium buys are usually better suited to players who can handle larger swings.

Bankroll Size	Suggested Bonus Buy Type
Small	Low Tier Buys
Medium	Standard Buys
Larger	Premium Buys
High Roller	Super Bonus Buys

Many modern slots offer more than one Bonus Buy option. Before choosing, check whether the higher priced feature actually gives better value. Look for upgrades such as:

• Extra free spins
• Guaranteed multipliers
• Sticky or expanding wilds
• Improved RTP
• Higher max win potential
• Exclusive bonus modes

The best Bonus Buy slots make each feature level feel meaningfully different.

Check RTP and Max Win

RTP and maximum win potential are two of the most important details to review before playing. RTP shows the theoretical long term return, while max win shows the highest possible payout.

Factor	Why It Matters
RTP	Helps compare long-term theoretical value
Max Win	Shows the game’s top payout potential
Volatility	Indicates how risky the slot is
Bonus Cost	Shows how expensive the feature is
Feature Type	Helps determine gameplay style

Many players prefer Bonus Buy slots with an RTP of 96% or higher where available.

Understand the Bonus Mechanics

Not all bonus rounds work the same way with some focusing on multipliers, while others use wilds, respins collections, or cascading wins.

Common Bonus Buy mechanics include:

Mechanic	What It Does
Multipliers	Boost winning payouts
Sticky Wilds	Stay in place during bonus rounds
Expanding Reels	Increase the playing area
Cascading Wins	Create repeated win chances
Respins	Extend gameplay after wins
Collectors	Gather symbols or values
Random Modifiers	Add unpredictable bonus effects

Understanding the feature before buying can help you avoid games that do not suit your style.
