In this selection, we have compiled what we believe to be the best online slots with a bonus purchase feature. So, make yourself comfortable and let’s start exploring them!
Gates of Olympus 1000 is an enhanced version of one of the most successful slots in online gambling history. Pragmatic Play took a proven formula and pushed it to the absolute limit.
Game Details:
The slot uses the Tumble system – winning symbols disappear and new ones fall in their place. This can create long chains of wins. The main feature is random multipliers (from 2x to 1000x) that drop onto the playing field and accumulate throughout the round.
The combination of recognizable mechanics, divine theme, and the new maximum multiplier of 1000x makes this slot essential for Bonus Buy enthusiasts. One lucky cascade with multiple multipliers can deliver a life-changing win.
Wanted Dead or a Wild set a new quality standard for Western slots and became Hacksaw Gaming’s flagship title.
Game Details:
Two main characters – bounty hunters – appear in the bonus round. Each has their own multiplier that grows with every appearance. The VS feature triggers a duel between the hunters, where their multipliers combine for colossal payouts. Unique Features:
Cinematic quality, unique duel mechanics, and the unpredictability of every bonus. This slot is a true blockbuster in the online casino world.
San Quentin is a legendary slot with one of the highest maximum wins in the industry: 150,000x the stake.
Game Details:
The prison theme is realized through unique xWays (expanding symbols), xNudge (shifting Wilds with multipliers), and Lockdown Spins (bonus spins with inmates) mechanics. Bonus Purchase Options:
San Quentin is a slot for true thrill-seekers. The 150,000x potential when purchasing Razor Split makes every bonus a potentially life-changing event.
Big Bamboo quickly became a favorite among casino streamers thanks to its unique Golden Bamboo mechanic and impressive maximum win.
Game Details:
Mystery symbols (bamboo stalks) reveal into matching symbols, creating large winning combinations. The main star is Golden Bamboo with multipliers from 2x to an incredible 10,000x! Bonus Features:
Big Bamboo perfectly balances bonus frequency and potential. One Golden Bamboo with a high multiplier can turn a modest bonus into a massive win.
Zeus VS Hades offers a unique concept – players choose their own fate by siding with the god of the sky or the lord of the underworld.
Game Details:
A 6×5 playing field with Tumble system. When purchasing the bonus, you choose:
Unique Features:
The ability to choose between two play styles makes Zeus VS Hades a universal slot. Want stability – choose Zeus. Ready to risk it all for maximum potential – your path lies in the realm of Hades.
The bonus purchase mechanic is straightforward: the player clicks the “Buy Bonus” button and pays a fixed amount, typically ranging from 50x to 500x the base bet, which instantly activates the bonus round. The purchase cost depends on several factors – the slot’s volatility (the higher the payout potential, the more expensive the bonus), the type of bonus round (many slots offer multiple options with different prices and potential), and the feature’s own RTP.
The main advantage of Bonus Buy is time savings and guaranteed access to the most exciting part of the game without waiting for scatters to land. However, there’s a flip side: high cost per purchase, the possibility of minimal wins even at maximum stakes, rapid bankroll depletion, and increased result volatility. Bonus Buy is a tool for those who value adrenaline over patience.
One of the most important aspects every player should know: RTP when purchasing a bonus often differs from RTP when triggering it naturally. This isn’t a bug or deception – it’s a mathematical feature built in by developers.
When you play the base game and catch a bonus “naturally” (through scatters), the slot accounts for all the bets you made leading up to that moment. The slot’s overall RTP (e.g., 96.5%) is calculated considering the entire game cycle: base game + waiting for bonus + the bonus round itself.When purchasing a bonus, you skip the base game and pay a fixed amount for instant access. Providers set a separate RTP for this feature, which can be either higher or lower than the slot’s overall RTP.
| Slot | Overall RTP | Bonus Buy RTP |
|---|---|---|
| Gates of Olympus | 96.50% | 96.50% |
| Sweet Bonanza | 96.51% | 96.48% |
| San Quentin | 96.03% | 94.00–96.03%* |
| Wanted Dead or a Wild | 96.38% | 96.38–96.46%* |
Depends on the selected bonus purchase option
The RTP difference between natural and purchased bonuses typically ranges from 0.1–2%. On a short run, this is barely noticeable, but over extended play, it can affect results. The main advantage of Bonus Buy isn’t mathematical – it’s temporal: you get instant access to the most volatile and potentially profitable part of the slot.
The best Bonus Buy slots are created by the industry’s leading studios, each with their unique signature style.
Pragmatic Play (Malta, 2015) is an industry giant behind Gates of Olympus 1000 and Zeus VS Hades, renowned for Tumble mechanics and consistent release quality.
Hacksaw Gaming (Sweden, 2018) is a cult favorite among streamers, giving the world Wanted Dead or a Wild, Duel at Dawn, and Folsom Prison with their extreme volatility and cinematic quality.
Nolimit City (Malta) is a provider for thrill-seekers, whose San Quentin offers a record-breaking maximum win of 150,000x through signature xWays and xNudge mechanics.
Push Gaming (UK, 2010) created Big Bamboo and Fire Hopper featuring unique Mystery symbols and multipliers up to 10,000x, perfectly balancing win frequency and size.
Endorphina (Czech Republic) is a veteran with over 10 years of history, whose atmospheric Voodoo showcases the studio’s mastery in creating thematic slots. Together, these providers set the gold standard for the Bonus Buy segment, offering games for every play style and risk appetite.
Bonus Buy slots have changed the game – literally. In my years working in the online gambling industry, I’ve seen many trends, but the bonus purchase feature has been a true game-changer.
For streamers and content creators, it’s a godsend: no more “warming up” a slot for hours waiting for a bonus – you can immediately show your audience the most exciting part. For regular players, it’s an opportunity to maximize their time and budget efficiency.
However, I must warn you: Bonus Buy is a high-volatility tool. The ease of purchasing bonuses creates an illusion of control, but each purchase is an independent event with the casino’s mathematical edge. I’ve seen players blow through their entire bankroll in mere minutes, buying bonus after bonus.
The slots in this review – Gates of Olympus 1000, Wanted Dead or a Wild, San Quentin, Big Bamboo, and Zeus VS Hades – represent the cream of the industry. They’re created by top providers, have fair RTP, and offer unique gaming experiences. You can find these games at the best online casinos that partner with leading providers and offer a complete catalog of Bonus Buy slots.
My advice: treat Bonus Buy as entertainment, not a way to make money. Set limits, don’t gamble with money you can’t afford to lose, and remember – the house always wins in the long run.
Play responsibly and may the multipliers be in your favor!
A Bonus Buy slot is an online slot machine that allows players to purchase instant access to the bonus round instead of waiting for scatter symbols to trigger it naturally. When you click the “Buy Bonus” button, you pay a fixed amount (typically 50x to 500x your base bet) and immediately enter free spins with multipliers and special features. This mechanic is also known as Feature Buy, Bonus Purchase, or Buy Feature.
Not necessarily. The mathematical return (RTP) when purchasing a bonus is often similar to or slightly lower than triggering it naturally. The key advantage isn’t profitability – it’s time efficiency. You skip potentially hundreds of base game spins and get instant access to the slot’s most volatile and exciting part. However, remember that each bonus purchase is an independent event, and results can vary dramatically due to high volatility.
Bonus prices reflect several factors: the slot’s maximum win potential (higher potential = higher cost), volatility level, and the type of bonus offered. For example, San Quentin offers four purchase options ranging from 80x (basic Lockdown Spins) to 2000x (Razor Split with 150,000x max win potential). More expensive options typically unlock enhanced features, additional multipliers, or special mechanics that increase winning possibilities.
No. Some jurisdictions have restricted or banned the Bonus Buy feature. For instance, the UK Gambling Commission prohibited this feature in 2019, considering it could accelerate problem gambling. Players in countries like Sweden, Spain, and certain other regulated markets may also find this feature disabled. Always check your local gambling regulations and verify whether the feature is available at your chosen online casino.
The most important strategy is bankroll management. Set a strict budget before playing and never exceed it. Consider that one bonus purchase at 100x bet equals 100 regular spins worth of wagering in a single click. Experienced players recommend having at least 10-20 bonus purchases in your budget to account for variance. Also, compare RTP between different bonus options within the same slot – some variants offer better mathematical returns than others.
