What Are Bonus Buy Slots?

Imagine paying €10 to skip the line at a theme park ride. That’s essentially how Bonus Buy Slots work. Except instead of roller coasters, you’re buying instant access to free spins, bonus rounds, or mini-games.

Understanding the "Buy Feature" Mechanic

The “Buy Feature” lets players pay a premium (usually 50x–800x their bet) to trigger a slot’s bonus round immediately. No spinning the reels for hours. No praying to the slot gods. Just one click, and boom! You’re in. Popularized by studios like Relax Gaming and Yggdrasil, this mechanic has exploded in games like Gates of Olympus and Savage Buffalo Megaways.

But here’s the kicker: the cost of the buy feature isn’t random. It’s calculated based on the game’s RTP and volatility. High-volatility slots often charge more for their bonus rounds, while low-RTP games might tempt you with cheaper, but riskier, buy-ins.

Why Players Love Bonus Buy Slots

Why gamble when you can… well, gamble faster? For many, the appeal boils down to:

  1. Instant gratification: Skip the base game’s “filler” spins.
  2. Predictable costs: Know exactly what you’re paying upfront.
  3. Strategic play: Target high-potential bonuses without burning cash on dead spins.

It’s no wonder Bonus Buy Slots dominate platforms offering new online slots. But before you splurge on that buy button, let’s talk about the golden metric: RTP.

The Role of RTP in Bonus Buy Slots

RTP (Return to Player) is the North Star for smart slot players. It tells you what percentage of your bets a slot will theoretically pay back over millions of spins. A 96% RTP? For every €100 wagered, you’ll get €96 back. in the long run.

How We Calculate Average RTP for Bonus Buy Slots

At FindMyRTP.com, we don’t just take developers’ word for it. We collect RTP data from online casinos, compare variations, and calculate averages. Why? Because the same games can come with different RTP settings to stand out (or squeeze profits). For example, Book of Dead might have a 96.5% RTP at Casino A but 94% at Casino B. Our data evens out these quirks to give you the real picture.

Why RTP Varies Between Casinos for the Same Slot

Surprise! Casinos can choose from a selection of RTP variants of the same game from a game provider. A game you might be used to playing at 96% one day, might be 94% another. Always check RTP per casino using tools like FindMyRTP. For deeper insights, explore our guide to casino software providers with the highest RTP.

Pros and Cons of Bonus Buy Slots

Advantages of Using the Buy Feature

  1. Instant rewards: No more waiting for bonus rounds.
  2. Budget control: Know your max loss upfront.
  3. Strategy-friendly: Target high-RTP bonuses exclusively.

Risks to Consider

  1. Volatility whiplash: Buying into a high-volatility bonus can vaporize your balance.
  2. Lower long-term ROI: Frequent buys eat into your bankroll faster than organic play.

How to Choose the Best Bonus Buy Slot for You

Prioritizing RTP vs. Volatility

  1. High RTP + low volatility: Steady returns.
  2. High RTP + high volatility: Big wins, bigger risks.

Checking Casino-Specific RTP Data

Always verify a slot’s RTP at your chosen casino. A game might have a 96% average but run at 94% on your platform. Use FindMyRTP.com’s comparison tools to avoid nasty surprises.

Conclusion: Smart Play with Bonus Buy Slots

Bonus Buy Slots are a double-edged sword. Used wisely, they’re a shortcut to adrenaline-pumping features and big wins. But without due diligence, they’re a fast track to empty wallets. Remember:

  1. Stick to high-RTP slots (95%+).
  2. Cross-check RTP across casinos.
  3. Gamble responsibly. Set limits and quit while you’re ahead.
