Best Bonus Buy Slots 2026: Top Games to Buy a Bonus and Increase RTP
Let's be honest: no one likes to "spin the void". Sitting for hours looking at the balance being eaten and waiting for three scatters is fun for everyone. Modern players in Canada are increasingly choosing bonus buy slots - games where action can be bought instantly.
Instead of a slow grind, you pay a fixed amount (usually between 50x and 100x the bet) and go straight to the main course — free spins or a bonus game. But did you know that in most cases, it's not only faster, but also more mathematically beneficial?
Below is a detailed guide to feature buy slots, an honest rating of games, and evidence of how the purchase affects your RTP.
What is Bonus Buy and why pay x100?
The mechanics are very simple: you click a button (usually "Buy Feature" or "Buy Free Spins"), pay a multiple of your bet, and the next spin is guaranteed to trigger the bonus.
Why experienced players choose buy bonus slots:
- Save time. You're missing out on the boring base game.
- Hunt for Max Win. The chance of catching the maximum win in a regular game is negligible. In the bonus, it is real.
- Increased RTP. This is the main argument in favour.
Important for players: If you are reading this from supported regions, remember: the the operator licence has banned the feature of buying a bonus. Players from supported regions are looking for alternatives on crypto projects. However, in Canada (including Ontario), this feature is completely legal and available in all licensed casinos.
The secret of mathematics: Why it is more profitable to buy a bonus (RTP table)
Many beginners think that the casino "screws up" the price. In fact, providers (Nolimit City, Big Time Gaming, Pragmatic Play) often reward high rollers by increasing the theoretical return to player (RTP) on purchase.
Here are the real numbers of popular slots. See how recoil changes:
| Slot (Game) | Provider | RTP in regular play | RTP when buying a bonus | Benefit |
| White Rabbit Megaways | BTG | 97.24% | 97.77% | +0.53% |
| San Quentin xWays | Nolimit City | 96.03% | 96.95% (with max buy) | +0.92% |
| Money Train 3 | Relax Gaming | 96.10% | 96.50% | +0.40% |
| Sweet Bonanza | Pragmatic Play | 96.48% | 96.51% | +0.03% |
| Extra Chilli | BTG | 96.15% | 96.82% | +0.67% |
Note: The RTP may vary slightly depending on the settings of a particular casino.
Conclusion: Mathematically, when you buy a bonus, you play with a lower house edge than if you spin the slot for hours.
Top 5 Best Bonus Buy Slots Ranked
We have tested dozens of games and selected five where buying a bonus gives the best emotions and winning potential.
1. Big Bass Splash 1000 (Best for Fishing Fans)
If you are a fan of fishing, then the big bass splash buy bonus is a must-have. Unlike the original version, here you catch lasso modifiers before the start of free spins.
- Buy price: 100x.
- Max Win: 5,000x.
- What's the Catch: You can catch "More Fisherman" or "Start from Level 2". This radically changes the course of the bonus. Buying here often pays off through retriggers (extra spins).
Verdict: A classic of the genre with improved mechanics.
2. Sweet Bonanza (Best for Low Budget Buys)
The most popular slot in Canada to get to know the feature. The Sweet bonanza buy feature costs the standard 100x, but the Tumble mechanic makes the game very dynamic.
- Buy price: 100x.
- Max Win: 21,100x.
- What is the feature: Multipliers from x2 to x100. If a combination plays on the screen and a bomb of x100 appears, even a bet of $0.20 will bring a huge win.
Verdict: The perfect balance for those who don't want to risk thousands of dollars.
3. Gates of Olympus (Best Multipliers)
"Grandfather" does not forgive mistakes, but can make you rich. Gates of olympus bonus buy gives you 15 free spins with an accumulating multiplier.
- Buy price: 100x.
- Max Win: 5,000x.
- What is the feature: The main difference from Sweet Bonanza is that the multiplier does not burn out. If you have accumulated x50 for the last spin and Zeus rolls another x500, the payout will be legendary.
Verdict: High volatility. Be prepared for empty purchases, but one payout will cover everything.
4. San Quentin xWays (Best for High Rollers)
The slot is not for the faint of heart. The San quentin bonus buy can cost up to 2000x the bet. This is the "Ferrari" of the slots world.
- Buy price: 100x, 400x, or 2000x.
- Max Win: 150,000x.
- What's the Catch: Buying for 2000x awards 5 Jumping Wilds with multipliers. The winning potential here is comparable to the jackpot.
Verdict: Only for experienced players with a large bankroll.
5. Money Train 3 (Best for Max Wins)
Relax Gaming have created a cult series. There are no fruits or cards, only harsh steampunk and online slots with bonus buys of the Money Cart mechanic.
- Buy price: 4 options (from 20x to 500x).
- Max Win: 100,000x.
- What is the feature: The "Persistent Necromancer" or "Persistent Collector" symbol can resurrect tiles that have already been played. This creates chains of wins that last for minutes.
Verdict: The best replay value on the market.
Price: How much does "Buy Feature" cost?
The market is established, and prices can be divided into three categories:
- Cheap Buys: 50x - 80x.
- Suitable for cautious players. They are often found in slots from Nolimit City (options with fewer spins) or Hacksaw Gaming.
- Industry Standard: 100x.
- Pragmatic Play's Gold Standard. You pay CA$100 on a $1 bet. Fair deal for high volatility.
- Super Buys: 200x - 2000x.
- Here, you pay for a guarantee of Wilds or a high starting multiplier. The risk is maximum, but the RTP in such purchases is usually the highest.
Pros and cons: Is it worth the risk?
Pros:
- RTP Boost: As we found out above, the math is on your side.
- No dead spins: You only pay for quality content.
- Flexibility: You can choose the cost of the bonus to suit your bankroll.
Cons:
- Variance: You can buy a CA$100 bonus and win $10. It hurts, and it happens often.
- Quick Loss of Balance: Without self-control, it is possible to lose a deposit in 5 minutes.
- Inflated expectations: Buying does not guarantee a "payout", it only gives a chance.

FAQ
In 80% of cases, yes. Providers (e.g. BTG and Nolimit City) officially indicate in the rules that the RTP when buying is higher by 0.2%-1.0%. Always check the "i" or "?" button in the slot.
No. The the operator licence (UK Gambling Commission) banned this feature due to the "excessive intensity" of the game. If you are in the UK, this feature is not available legally.
Slots from Hacksaw Gaming often offer a "BonusHunt" feature – this is not a direct purchase, but a 5x increase in the bonus chance for triple the price of a spin (3x). There are also cheap purchases in the "Book of..." series (sometimes from 50x).
Almost always - high or extreme. The slot should compensate for big wins with many small (or empty) bonuses. Be prepared that 3 out of 5 purchases may not pay off.
It depends on the casino. NOTE: In many casinos, buying a bonus while the welcome bonus is active is prohibited or limited to a maximum bet (usually $5). Be sure to read the T&C before buying if you have an active deposit bonus!
High-cap titles such as Tombstone RIP, San Quentin xWays, and Money Train 4 publish max-win caps above 100,000× the base bet. AGCO advertising-standards advisory: high-volatility cap exposure is statistically rare; verify the in-game RTP-with-buy figure and set a session limit before play.
Bonus buys are the only way to hit a Max Win.
What kind of nonsense is this?
Casinos benefit from you buying bonuses. You drain your balance faster and lose all control. “Mathematically better,” yeah right, tell that fairy tale to someone else. The casino is always in profit.
No one’s forcing you to buy 2000x bonuses. There are cheaper options. Sweet Bonanza, for example, has standard x100 buys. And yes, the RTP really is higher - it’s written in the provider’s rules, not made up by the casino. You just need to read the slot info.
Gates of Olympus is top tier. The best thing is that the multiplier doesn’t reset. Yesterday I bought a bonus for 200 CAD, built it up to x50, and on the last spin it dropped a x100. Cashed out 4 grand and bought a new iPhone. Gotta love Pragmatic!
Finally, a decent article. Seriously, who even grinds base game for hours anymore? You sit there like an idiot waiting for those three scatters, and it just keeps eating your balance. I’d rather drop $100 straight into Bonanza and get some action than bleed a dollar at a time for two hours. Time is money, guys.
Yeah, and you’ll lose that hundred in 10 seconds. Bonus buys are evil. The volatility is insane. Yesterday I bought San Quentin for 2000x, thought my life was about to change. Yeah right, paid x15.
