Bonus buy slots, or feature buy slots, are games that allow a player to directly enter the bonus round without triggering the feature in a conventional way. For this privilege, a player will pay, in most cases, 100 times their stake, but amounts can range from as little as 50x bet up to an incredible 5000x the overall stake. Fear not, though; we’re giving you the facility to play free bonus buy slots and activate in-game bonus features and modifiers without making a deposit or signing up. Our visitors have access to a comprehensive list of slot games with bonus buy capabilities, so they can get straight into the thick of the action without spinning the reels on a single base game.

How Do Bonus Buy Slots Work?
Slots where you can buy the bonus, for the most part, precisely the same as any other game. They can have bonus rounds, modifiers, free spins features, and a variety of themes that appeal to all players. So, how exactly do they work?
Well, I’m pleased to report that it couldn’t be easier. Any slots with a feature buy will have a button positioned near the reels (usually to the left) displaying the price to initiate the bonus feature. In the case of providers like Pragmatic Play, this will be one button typically showing the value of 100x your current stake. In contrast, other developers like Nolimit City provide a tiered buy menu where different entry levels into the bonus round are offered.
Highest RTP Bonus Buy Slots
The number of bonus buy slots now available is huge and continues to grow by the day, so finding the best games in this slot genre could take you days or even weeks. However, we can help cut through this time as each game we list here on our platform ranks in each category it is associated with according to its Return to Player percentage rate. So, if you want to play bonus buy slots with a high RTP, you can find them in our table below, which refreshes each time a game has a high enough RTP to disrupt the current list.
| Slot Name | RTP |
|---|---|
| 1. Apollo 77 | 98.00% |
| 2. Legend Of Senteng | 97.76% |
| 3. 9 Blazing Cashpots | 97.34% |
| 4. Cyber Heist | 97.34% |
| 5. Kraken's Hunger | 97.20% |
| 6. Adventures | 97.10% |
| 7. Super Size Atlas | 97.03% |
| 8. Sticky Piggy Slot | 97.03% |
| 9. Bull Treasure | 97.00% |
| 10. Cleopatra's Treasure | 97.00% |
Feature Buy Vs Natural Trigger, What’s Best?
This is a highly debated topic amongst many players, and it would seem that opinion is split. Yes, we do see max wins coming from a bonus buy, but from our extensive testing of the slots we review, it is easy to go 10 or 20 buys on these slots without ever seeing a profit. Obviously, this is just a small sample size, but it is a pattern we see repeatedly.
We are all entitled to express our views on this matter, but overall, from our own experiences testing and playing feature slots for real money, a natural feature trigger plays better than one that has been bought. Unfortunately, though, in some instances, providers develop certain slots where the highest possible bonus features can only be achieved through buying them.
Feature Buy Slots With Gambling Options
Whether you agree with the concept or not, gambling the volatility of your bonus has also become a significant factor in the when playing any of the titles in this series of games. The downside to gambling bonuses is that if you lose one of the initial gambles, the feature can potentially end there without you having a single spin of the reels and losing all your stake money.
As many slots with a buy feature continue to be developed by providers, we have started to see various adaptations to the feature gamble and the possibility of not only gambling your free spins but the chance to increase your starting multiplier as well. This takes the chance of altering the bonus round volatility to a whole new level, and if Lady Luck is shining down on you, it’s possible to potentially stack the chips in your favour to a point in the gamble where a considerable amount of extra free spins are awarded, a higher multiplier can be taken, or in the ideal scenario like the gamble wheel of Vikings Unleashed, both free spins and multipliers are maxed out to begin the feature with.

Bonus Buy Slots UK
October 2019 saw the UK Gambling Commission request online casinos to remove the ability for UK players to buy a bonus feature on any slots. The bonus buy option has long been debated as to whether it encourages irresponsible gambling, and the regulator for the UK finally decided to call time on the controversial feature.

Our Conclusion: The original Fire in the Hole is a brilliant game, and this is very similar, so it was always going to be good. It will be subjective whether enough has been done to refresh it and justify a sequel as not much has changed, which won’t sit well with some players, but the additions that have been made are positive ones. In my view, this is an improvement on the last version, and I’m not offended that the tweaks have been minimal. It’s a great title.

Our Conclusion:
San Quentin 2: Death Row is every bit the brutal, high-octane sequel you'd expect from Nolimit City. If the original volatility of San Quentin scared you more than the thought of spending a night at San Quentin, then the sequel will have you comparing it to a six-month stretch with its cast as your cellmates. With a jaw-dropping 200,000x the stake maximum win and the return of features like Jumping Wilds, xWays, and Razor Splits, the slot is not here to play nice - it’s here to dominate. Then again, isn't that what we love about NLC slots?

Our Conclusion:
Sometimes game providers get it wrong and make a sequel where one isn't needed, but in the case of Dead or Alive 2, NetEnt has produced an epic slot with bags more features and a huge max win.

Our Conclusion: Jammin Jars was released on the 14th of September 2018 and has proven to be one of the most successful titles in the history of iGaming. The slot is genuinely stunning in every aspect, from its unique theme and fantastic design to the sheer excitement that the free spins feature can bring when your jars are all close together with juicy multipliers attached to them. This is, without a doubt, one of the best online slots I have played, and it will continue to remain one of my favourite games for the foreseeable future. Highly recommended, so give it a try.

Our Conclusion: Bonanza Megaways is quite possibly the best online slot ever to be created. Not only was it the first of its kind in the Megaways series, but it would go on to inspire hundreds of new games that featured the combo of an unlimited win multiplier and cascading reels.Such was the success of Bonanza that Big Time Gaming even added their Megapays Jackpot Engine to it, so players could enjoy all the thrills they had experienced before, but with Bonanza Megapays, they now had the chance to win a life-changing amount of money too.To conclude, Bonanza Megaways is rated so highly at Demoslot that it is currently the only slot ever to receive the MAX WIN rating and a perfect score of 10. Simply put, this is a sensational slot that every player must try at least once.;
Bonus Buy Slots Final Thoughts
These styles of slot games are here to stay as a form of online gambling, well, for now, at least. So, if you are playing from a jurisdiction where buying bonuses are active, your overall play can be enhanced if you use this tool correctly. The danger of buying bonuses on online slots multiple times is that players could get carried away and spend more than they would like, as well as hitting heavy losses. However, if you have deposit limits in place and play responsibly, then there is no reason why you can’t activate a few bonus features during one of your playing sessions.
FAQ's
If you accept a deposit bonus at any slot site, it will likely have rules and restrictions on a certain amount you are allowed to bet per spin, meaning it is unlikely you’ll be able to use games where you can buy the bonus to count towards any wagering. That being said, it is always worth checking with the support team at the casino you are playing at, especially if you are a higher roller, as exceptions are often made on bonus funds or a deposit bonus for those who play with a bigger bankroll, possible allowing you to utilise a feature buy slot game against your wagering.
All online gambling, of course, comes with an element of risk, but many slots where bonus games can be bought are certainly categorised as higher risk due to the fact you can lose more money than usual in such a short space of time. We recommend you extensively try our demo slots section dedicated to bonus buy feature slots so you can see how each title behaves, what the pitfalls are, and make yourself fully aware of how quickly you can burn through your bankroll if you hit a bad run of luck as you continue to buy the bonus.
It’s hard to argue a case where you could definitively say that buying bonuses for a certain amount is better value than just spinning the reels of any online slots normally. It would be much fairer to say that combining a mixture of the two will bring higher levels of entertainment to your session. However, it’s important to remember that you should only really consider buying a bonus if the size of your bankroll is at least double the price of the feature buy. This way, you will not potentially deplete your bankroll in just one round and can still enjoy normal gameplay and give yourself another chance further down the line to buy more bonuses if you can increase the size of your balance.
