Online slots have seen a major evolution over the past decade, with developers constantly seeking new ways to make gameplay more engaging and rewarding. One of the most impactful innovations in recent years is the bonus buy feature—a mechanic that allows players to skip the base game and purchase instant access to a slot’s bonus round. These features have quickly become a favorite among high-risk, high-reward players, transforming the way slots are played across countless platforms. But with great potential rewards come certain risks, and understanding how bonus buys work is essential before diving in.
What Are Bonus Buy Features?
Bonus buy, sometimes labeled as “Feature Buy” or “Buy Bonus,” is a slot mechanic that lets players pay a set amount to trigger the game’s bonus round instantly. Instead of waiting for the bonus to land naturally through random base game spins, players can fast-track their way to the action by purchasing it directly.
The cost of a bonus buy typically ranges from 50x to 200x the base bet, depending on the game and the volatility of the bonus feature. Some advanced games even offer multiple bonus buy tiers, allowing users to select different versions of the bonus with varying risk and reward profiles.
Why Bonus Buy Is So Popular

The popularity of bonus buy features is driven by several key factors:
1. Immediate Excitement
Waiting for a bonus round to trigger can be frustrating, especially on high-volatility slots. Bonus buy gives players instant access to the most exciting part of the game, eliminating the grind and keeping gameplay dynamic.
2. High Win Potential
Bonus rounds often come with multipliers, free spins, or unique mechanics that offer significantly higher win potential compared to base game spins. Players see the feature as a shortcut to the slot’s biggest payouts.
3. Better Time Efficiency
For players with limited time or those chasing big wins, buying into the bonus skips the waiting and allows for quick, high-stakes gaming sessions. It suits both streamers and casual players looking for adrenaline-fueled gameplay.
4. Enhanced Streaming Appeal
Online slot streamers have helped fuel the popularity of bonus buy features. Watching massive wins unfold in a matter of seconds is entertaining and shareable, making bonus buys a staple in live casino content.
Popular Games Featuring Bonus Buy
Many top software providers now include bonus buy options in their slots. Some of the most popular titles include:
- “Money Train 2” and “Money Train 3” (Relax Gaming) – Known for explosive bonus features and upgradeable symbols.
- “Sweet Bonanza” (Pragmatic Play) – Offers a high-variance free spins feature with multiplier bombs.
- “San Quentin” (Nolimit City) – A volatile slot with unique mechanics and expensive, but potentially huge, bonus buys.
- “Extra Chilli” (Big Time Gaming) – A game where the bonus can be bought and then gambled for more spins, adding extra layers of risk and reward.
These games are designed with the bonus buy mechanic at their core, offering balanced pricing and return-to-player (RTP) rates adjusted for fairness.
Risks of Bonus Buy Features

While the appeal is undeniable, bonus buys also come with significant risks:
1. High Volatility
The bonuses you’re buying are often very volatile, meaning it’s possible to pay 100x your bet and walk away with just a small return. Some bonuses may yield 5x–20x results, creating a frustrating and expensive experience.
2. Potential for Fast Losses
Because you’re wagering large sums per feature, bankrolls can disappear much faster than with regular base game spins. The frequency and size of bets increase the potential for rapid losses.
3. Accessibility to Problem Gamblers
Some regulators argue that bonus buy features encourage irresponsible play, as they simulate high-stakes gambling with fast results. This has led to bans or restrictions in some jurisdictions.
4. Not Available Everywhere
Due to regulatory concerns, bonus buys are not allowed in some markets, including the United Kingdom. As a result, players may need to find alternative versions of the same slot that remove or lock the feature.
Responsible Use of Bonus Buy
For those who choose to use bonus buys, it’s critical to do so responsibly. Here are some tips:
- Set a strict budget and avoid chasing losses.
- Understand the RTP and volatility of the bonus round before purchasing.
- Don’t expect guaranteed profits—treat the feature as a fun gamble, not a shortcut to winning.
- Avoid repeated purchases after big losses, which can lead to emotional decisions and further losses.
Bonus buys are best used occasionally and strategically, especially when the game’s bonus feature is both entertaining and offers realistic win potential.
Final Thoughts
The rise of bonus buy features has reshaped how players engage with online slots. By offering instant access to the most exciting part of the game, they create a more thrilling, high-stakes experience for those who seek it. While the feature isn’t without its risks, it continues to grow in popularity thanks to streamers, advanced mechanics, and player demand for more control over gameplay. As with any betting feature, the key to enjoying bonus buys lies in understanding how they work—and using them wisely within your budget and play style.
