With Bonus Buy slots, players can skip this process by paying a set price, usually a multiple of their stake (some games offer different price points which come with varied volatility), once paid you jump straight into the feature, where the biggest wins and most exciting gameplay elements are typically found.

These slots have become extremely popular among UK players because they offer more excitement, faster gameplay, higher win potential all of which you are in control of. Instead of spending time chasing the bonus feature, players can access it immediately, making the experience more engaging from the get-go!. Bonus rounds often include powerful features like multipliers, cascading wins, expanding symbols, or re-spins, all of which can lead to significantly larger payouts and the games highest wins. This combination of instant access and the potential for big wins makes Bonus Buy slots especially appealing to British slots lovers.

How Much Do Bonus Buy Slots Cost?

The cost of Bonus Buy slots varies depending on the game, but it is always calculated as a multiple of your base stake (bet size). This means the higher your stake, the more expensive the bonus buy becomes.

Typical Bonus Buy Price Ranges:

• Low Cost Bonuses: 50x – 75x your stake
• Standard Bonus Buys: 80x – 150x your stake
• Premium Bonus Buys: 150x – 300x your stake
• Super Bonus / Enhanced Features: 300x – 500x+ your stake

Example:

If you are betting £1 per spin:

• 100x bonus = £100
• 200x bonus = £200
• 500x bonus = £500

Some games even offer multiple bonus options, such as:

• Standard bonus (cheaper, lower potential)
• Enhanced bonus (more expensive, higher win potential)

What Volatility Do Buy Feature Slots Have?

Bonus Buy slots are almost always medium-high to high volatility, and in many cases very high (extreme) volatility.

Volatility Explained:

• Medium Volatility: Balanced wins, moderate risk
• High Volatility: Bigger wins but less frequent
• Very High / Extreme Volatility: Rare wins, but massive payout potential

Why Bonus Buy Slots Are High Volatility

Bonus Buy slots are designed to give players access to the most valuable part of the game (the bonus round), where:

• Multipliers can stack
• Free spins can retrigger
• Special symbols (wilds, collectors, etc.) activate
• Maximum win potential is unlocked

Because of this, the games are built so that:

👉 You may not win back your bonus cost
👉 But when you do win, payouts can be very large (100x–10,000x+)

Typical Volatility by Developer

• Pragmatic Play: Medium-High to High
• Hacksaw Gaming: High to Very High
• Nolimit City: Very High / Extreme
• Relax Gaming: High
• Push Gaming: Medium-High to High

Risk vs Reward Breakdown

Factor	What It Means
Cost	High upfront spend (often 100x+)
Risk	You can lose the full bonus buy amount
Reward	Potential for very large wins
Frequency	Big wins are less common
Gameplay	Fast-paced, feature-focused

Key Takeaway

Bonus Buy slots typically cost anywhere from 50x to 500x+ your stake and are designed with high or very high volatility. This means they offer fast access to big-win potential, but also come with a higher level of risk compared to standard slot play.
