What Are Bonus Buy Slots?

Bonus Buy Slots, also known as “Buy Feature Slots” or “Buy Free Spins” have become incredibly popular across the world and are currently one of the most played slot categories alongside Megaways. These games offer direct access to the bonus rounds at any given time for a set fee, making it a super exciting option for players who love to jump straight into high risk, high reward action. Whether you call them buy feature slots or buy free spins, the concept remains the same… cut the waiting time and get to the good part of the game which offers the biggest winning potential.

How Much Do Bonus Buy Slots Cost?

Bonus Buy slots offer players the option to pay directly for access to a game’s most exciting feature…. the bonus rounds. The cost of activating these bonus features varies depending on the slot title, volatility and the rewards tied to the bonus mechanics (max win amount). On average, bonus buy prices range from 50x to 200x your base bet, although some games offer flexible pricing models with multiple tiers.

Here’s a breakdown of typical bonus buy costs and what you can expect at each level:

💸 20x – 75x Your Bet

This price point is at the lower end (cheapest) and usually linked to the most basic free spins or bonus buy mode available in the game. These options tend to be low to medium volatility, which means payouts are more frequent but generally smaller in size.
Popular examples include:

• Chaos Crew 2 (Hacksaw Gaming) – Low-cost bonus buy with quick access to re-spins.
• The Dog House Megaways (Pragmatic Play) – Standard free spins with sticky or raining wilds.

💥 100x Your Bet

The most common bonus buy cost is 100x, this gives you access to the game’s standard bonus round with balanced volatility around medium or in some cases medium/high. This is where you’ll find decent win potential mixed with a fair risk level, making it the perfect choice for most players.
Popular examples include:

• Gates of Olympus (Pragmatic Play) – Enter the famous multiplier packed free spins.
• Book of Shadows (Nolimit City) – Gamble for expanding symbols with massive win potential.
• Sugar Rush (Pragmatic Play) – Cascading wins and multiplier zones create exciting bonus action.

🔥 150x – 200x Your Bet

The highest cost of slots where you can bonus buy are often priced between 150x and 200x your stake, or in some cases even up to 500x. These super volatile features offer higher risk but come packed with enhanced rewards such as guaranteed multipliers, stacked wilds or added reels, all of which can lead to the games maximum win potential.
Popular examples include:

• Dead or a Wild (Hacksaw Gaming) – Three different high-stakes bonus buys, including Duel and Dead Man’s Hand.
• Gemini Joker (Betsoft) – Super bonus buy adds multiplier reels and respin bonuses.
• Gem Elevator (Pragmatic Play) – A high risk slot where the premium bonus round promises max win potential.

⚙️ Variable & Tiered Bonus Buy Options

Some new slot titles give you the ability to choose from multiple bonus types, each priced differently based on volatility and added features. This flexibility makes the games hugely popular to all types of players, a great example is:

Money Train 3 (Relax Gaming) – Offers a variety of bonus buys:

• 20x (1 Spin Feature) – Guarantees the bonus game is triggered with 1 starting spin. Every new symbol that lands in the bonus game will reset the spin count to 1.
• 50x (2 Spin Feature) Guarantees the bonus game is triggered with 2 starting spin. Every new symbol that lands in the bonus game will reset the spin count to 2.
• 100x (Original Feature) Guarantees the bonus game is triggered and every new symbol that lands in the bonus game will reset the spin count to 3.
• 500x (Persistent Feature) Guarantees the bonus game is triggered with 1 persistent symbol. Every new symbol that lands in the bonus game will reset the spin count to 3.

How Buy Feature Slots Impact RTP (Return to Player) Percentages

When considering playing any online slot, Return to Player (RTP) is one of the most important factors to look at. It reflects the percentage of total wagered money that a game is expected to pay back to players over time. But did you know that using the bonus buy feature can actually affect the RTP?

Let’s explore how buying the bonus round can fluctuate RTP payout percentages and why this matters to your gameplay.

🎯 RTP Basics: What You Need to Know

RTP is usually calculated based on thousands or even millions of simulated spins. It’s a long term average projection, not a guarantee of individual results. For example, a slot with 96% RTP is expected to return £96 for every £100 wagered, over an extended period of time. The higher the RTP percentage, the more appealing it is to players as they are more likely to see better returns, however please note this is not a guarantee as it works to an average over a prolonged period of time.

💡 Bonus Buy = Higher RTP?

In many popular slots where you can buy the bonus, using this feature can slightly increase the RTP compared to playing through the standard base game. That’s because you skip past the lower paying regular spins and head straight into the bonus round where the biggest payouts typically happen.

Examples of RTP Differences:

• Standard Game Mode RTP: Typically sits between 94% and 97%.
• Bonus Buy RTP: Often increases to 97% to 99.60%, depending on the game.

• Curacao eGaming
