1. Money Train 2

Relax Gaming’s Money Train 2 delivers a thrilling Wild West adventure on a 5×4 grid with 40 paylines. Visually stunning and packed with features, this title elevates the original to new heights. The base game has a Respin mechanic: whenever you land at least one high-value symbol, you trigger a respin that keeps locked symbols in place while adding new rows. Unlocking up to two extra reels and expanding your winning potential dramatically.

At the heart of the action is the “Money Cart Bonus Round”, where you collect symbol multipliers and special modifiers: Collector, Payer, Sniper and more to build an ever-increasing prize pool. When the board fills completely, it unlocks additional reels, pushing excitement into overdrive.

For those who can’t wait, the Bonus Buy feature lets you purchase direct entry into the Money Cart round for 100× your stake. So if you’re betting €1 per spin for example, the bonus buy is going to cost you €100 to unlock.

3. Dead or Alive 2

NetEnt’s Dead or Alive 2 is the quintessential Wild West sequel, marrying nostalgic charm with modern volatility. This 5×3, 9-payline slot plunges players into high-stakes showdowns, where three distinct free spins modes (Old Saloon, High Noon Saloon, and Train Heist) offer varied multiplier and sticky-wild mechanics for relentless excitement.

During base play, it’s purely “paylines” action, but feature-triggering scatters (three or more) transport you into one of the bonus rounds of your choice, each promising its own path to potential fortune.

The high volatility ensures that wins arrive infrequently but with the promise of substantial rewards. Up to 111,111× your bet in free spins! For those eager to bypass the grind, the Feature Buy option guarantees entry into the free spins at the cost of 100× your stake, placing you straight into the heart of the action.

Rich, atmospheric sound design and rugged, hand-drawn symbols (badges, pistols, and cowboy boots) complete the immersive experience, making every spin feel like a cinematic standoff.

5. Punk Rocker

Nolimit City’s Punk Rocker is a homage to the rebellious spirit of the 1970s punk movement, delivered on a dynamically expanding 5-reel grid. Starting with a classic 3-row, 243-way setup, the game’s xWays Mystery Symbols can stack up to 6 high: unlocking as many as 46,656 ways to win.

Every win triggers a Riot Respin with sticky wilds, while Anarchy Free Spins (3 scatters) and Civil War Free Spins (4 scatters) propel you into two distinct bonus modes, each packed with moving wilds and multiplier-rich modifiers for truly anarchic payouts.

With its high volatility, Punk Rocker caters to thrill-seekers prepared to weather dry spells for a shot at massive rewards with up to 15,072× your stake. The frenetic soundtrack, graffiti-splashed visuals, and hand-drawn punk characters reinforce the game’s anti-establishment theme, while the NoLimit Shortcut feature allows impatient players to buy straight into the free spins rounds.

6. Big Bass Bonanza 1000

Now to a slot that many of my favorite Youtube streamers promote daily. Pragmatic Play’s Big Bass Bonanza 1000 takes its beloved fishing theme to explosive new depths on a classic 5-reel, 10-payline grid. The core appeal lies in its Free Spins round: landing three, four, or five scatter symbols grants 10, 15, or 20 free spins respectively, during which the Fisherman Wild collects all visible Fish Money symbols worth between 2× and 1,000× your stake each.

Collect four Fisherman Wilds to retrigger spins and unlock higher multipliers, potentially yielding massive payouts.

This iteration creates a very high volatility profile, appealing to thrill-seekers. For players eager to dive straight into action, two Bonus Buy options are available:

• A regular free spins buy at 100× your bet
• A Super Free Spins buy at 450× your bet

The latter increasing the chance of landing the coveted 1,000× Fish symbols during bonus play. Which one I prefer? Oh you already know.

7. Chilli Heat

Pragmatic Play is on fire with Chilli Heat bonus buy slot. This is is a fiesta-themed 5×3, 25-payline slot that transports players to the streets of a Mexican carnival. Symbols include Mariachi musicians, tequila shots, hot sauce bottles, and even a cheeky Chihuahua, all rendered in bright, detailed graphics.

The game’s heart is the Sizzling Respin round triggered by landing six Money symbol scatters where only Money symbols spin, and each new symbol resets your respins, offering the chance to fill the entire grid with cash prizes. Alongside stacked Wilds and traditional free spins, this respin mechanic delivers the bulk of the big wins.

With a medium-high volatility profile, Chilli Heat balances frequent smaller wins in base play with the potential for explosive payouts during the Money Respin. For those eager to dive straight into the heat, the respin feature can be purchased for 100× your stake, guaranteeing immediate entry into the bonus round. A default RTP of 96.5% ensures that, over time, the game remains competitive among its peers.

What is a Bonus Buy Feature in Slots?

A bonus buy is essentially a fast-track ticket to the most exciting part of a slot game – the bonus rounds.

You are paying to enter the bonus feature, bypassing the base game’s usual trigger requirements. For players who crave immediacy, it’s tremendously appealing. You know exactly what you’re getting: a guaranteed series of free spins, respins, or other high-payout mechanics. That clarity allows you to budget precisely, you decide up front whether the potential reward justifies the cost. It also gives you control over your session’s volatility: if you’re chasing big wins and don’t mind the risk, you can buy your way in; if not, you can stick to the base game.

Of course, buying a bonus isn’t without its downsides. You’re laying out a hefty chunk of your bankroll in one go, and there’s no safety net if the bonus doesn’t pay off. So let’s have a closer look to the pros and cons of bonus buy slots.

Hot To Choose Bonus Buy Slot?

At the end of the day, it’s all about entertainment and fun. so there are no rights and wrong here. If you really fancy a particular slot, there is no need to play a different one. With that being said, this is what I look for as a full time online casino and game tester:

• Volatility Profile

  • High-volatility slots deliver rare but life-changing wins; expect larger swings in your balance.

  • Medium- or low-volatility games offer more frequent, smaller payouts, making your bonus buys feel less punishing when they don’t pay off.

• Bonus Buy Cost vs. Bankroll

  • Check the buy-in multiple (e.g., 50×, 100×, 500× your stake) and make sure it fits comfortably within your session budget.

  • Never spend more than a small percentage (5–10%) of your total bankroll on a single bonus buy.

• Return-to-Player (RTP) Percentage

  • Higher RTPs generally indicate better theoretical returns over time, even in a bonus-buy round.

  • Compare RTP values of both the base game and the feature buy option, since some games boost RTP during paid bonuses. Check out our best RTP slot article to find the best ones straight away.

• Maximum Payout Potential

  • Look for slots with clear maximum win caps – e.g., 5,000×, 20,000×, or 50,000× your bet to set realistic expectations.

  • If chasing a “once-in-a-lifetime” jackpot, prioritize titles whose top prizes justify the bonus-buy cost.

• Game Theme and Engagement

  • Choose a theme you genuinely enjoy. Whether it’s mythology, heist, adventure, or sci-fi to keep the experience entertaining, regardless of outcomes.

  • Immersive sound design and high-quality graphics can make long sessions more enjoyable.

• Provider Reputation and Fairness

  • Stick with established developers (NetEnt, Pragmatic Play, Nolimit City, Relax Gaming, etc.) known for audited RNGs and transparent mechanics.

  • Read player reviews or trusted slot-review sites to confirm that the bonus-buy feature works as advertised.

• Regulatory Accessibility

  • Verify whether bonus buys are allowed in your jurisdiction, some regions restrict or ban these mechanics.

  • Always play at licensed casinos that adhere to responsible-gaming standards and offer robust player protections.

• Session Management and Limits

  • Before purchasing a bonus, set loss and purchase limits to prevent impulsive spending.

  • Use session timers or deposit caps to keep your play disciplined and fun-focused.

Summary: Should I Play Bonus Buy Slots?

As long as you set a limit for yourself and control your gaming habits – of course you should include a bonus buy here and there! It’s risky business however, it is extremely fun and thrilling but you must be aware of that there is no guarantee for success or a good return on your purchase.

• To summarize, play the slots that you enjoy and brings you joy rather than chasing big wins.
