The biggest wins from slots can usually be won from the game’s bonus rounds or Free Spins.

However, to reach the Free Spins, you often need to spin on average more than 100 times to trigger the bonus feature. In some cases, even several hundred times, and that is the average.

To give players more choices for faster access to bonus games (or a shortcut), game studios have developed the Bonus Buy Feature, also called Feature Buy. These are not available in all jurisdictions, though.

On this page, you will find the best bonus buy slots and info on online casinos where you can play them. We also share an extensive guide on everything you need to know about Bonus Buy Slots, its mechanics, and all your different options.

Some slots are released with various RTP versions. Check our slot reviews to find the best-paying versions.

Top 25 Best Bonus Buy Slots in 2024

  • 50x: 3 Wild Cats

There is also a Christmas-themed version of this slot available called Xmas Drop.

  • 157x: Free Spins with 3 starting rows

RTP94.48% | 96.52%

Big Bamboo is one of Push Gaming’s biggest max win slots, as you can win up to 50,000x the bet.

This slot might come across as something nice and relaxing, but it couldn’t be further from the truth, as Big Bamboo is tailored towards highly volatile players looking for risky slots.

Max wins won’t come around too often, though, as the max win probability is 1 in 21 million spins.

For a shortcut to the main action, players can choose to buy the following features in Big Bamboo:

  • 99x: 7-9 Free Spins with no multiplier added
  • 179x: 7-9 Free Spins with a starting multiplier of x3

We know there are endless Big Bass slots and other fishing-themed slots out there, but they are hugely popular.

One of the best ones is Big Bass Splash, and it also offers players the option to buy the Free Spins by paying 100x the bet.

Before the Free Spins start, you may win extra modifiers, and during the bonus game, you want to collect Fishermen Wild Symbols to increase spins and the multiplier values.

18. Buffalo Toro (ELK Studios)


Min bet0.20
Max bet50
Max win50,000x
Bonus buy cost10x – 500x

Buffalo Toro from ELK Studios is one of the best ones released in recent years, where you can buy bonuses.

These include:

  • 10x: Matador Respin
  • 25x: Toro Goes Wild
  • 50x: Rampage Reels during 3 spins
  • 100x: Free Spins
  • 500x: Super Bonus game

Although this slot is part of ELK Studios’ 94% RTP range, it’s one of the best games from their Toro series, packed with features, superb graphics, and a great soundtrack.

17. Nitropolis 4 (ELK Studios)


Min bet0.20
Max bet100
Max win50,000x
Bonus buy costx2 – 500x

  • 10x: Two features from the Nitro Booster
  • 25x: Spin with Max Rows & Both Ways

RTP88.41% | 92.28% | 94.32% | 96.24%
Min bet0.10
Max bet100
Max win10,000x
Bonus buy cost129x – 200x

There are plenty of ancient Egyptian-themed slots out there, but none really like Hand of Anubis, with its darker theme and a step away from the standard expanding symbols we are used to when playing these slots.

This slot also allows players to buy their way into the Free Spins.

In Hand of Anubis, you have two options:

  • 129x: Underworld bonus
  • 200x: Judgement bonus

15. Fruit Party (Pragmatic Play)


RTP94.45% | 95.48% | 96.47%
Min bet0.20
Max bet100
Max win5,000x
Bonus buy cost100x

Fruit Party is one of Pragmatic Play’s most popular Cluster Pays slots, taking the classic fruit machine to a modern version.

The Free Spins don’t trigger too often organically, though, as it happens on average 1 in 403 spins, so the Feature Buy option with a 100x cost can be tempting to use in this game as a shortcut to the main action where you can land higher multipliers than in the base game.

14. Madame Destiny Megaways (Pragmatic Play)

madame-destiny-megaways-slot bonus buy

RTP94.63% | 95.70% | 96.56%
Min bet0.20
Max bet100
Max win5,000x
Bonus buy cost100x

Madame Destiny Megaways can often be found in online casinos’ top lists as it’s an entertaining game with simple features.

To buy the bonus, you need to pay 100x the bet size used to spin, and it starts with a Wheel of Fortune that determines the number of spins and multiplier used during the Free Spins. Possible outcomes are 5-12 spins and 2x – 25x multiplier to be added to each win.

13. The Dog House Megaways (Pragmatic Play)


RTP94.55% | 95.53% | 96.55%
Min bet0.20
Max bet100
Max win12,305x
Bonus buy cost100x

This popular Megaways slot can deliver wins of up to 12,305x the bet and is a sequel to the classic The Dog House slot.

The Dog House Megaways one of few slots that are even better as a Megaways version, as the magic from the original version has been kept while adding some new twist to the mix that makes this slot great.

12. Book of Power (Relax Gaming)


RTP94.00% | 96.11%
Min bet0.10
Max bet30
Max win15,000x
Bonus buy cost100x – 200x

Book of Dead is the most popular “Book of” slot online. It crushes the competition year after year. But you can’t buy bonuses on Play n GO slots as the feature doesn’t exist on their games.

What if an even better version was out there regarding maximum win potential, graphics, and features? Book of Power ticks those boxes while offering players the option to buy bonuses.

You can buy the Free Spins by paying 100x or the Power Free Spins for 200x the bet amount used to spin.

11. Razor Returns (Push Gaming)


RTP88.83% | 90.55% | 94.49% | 95.40% | 96.55%
Min bet0.10
Max bet100
Max win100,000x
Bonus buy cost106x – 550x

Razor Shark is one of Push Gaming’s biggest hits, but you can’t buy bonuses on that slot.

So in 2023, they released the sequel Razor Returns with more features, an even higher max win potential, and not one but five different bonuses to buy through the Feature Buy option.

Your options are:

  • 106x: 3 Free Spins
  • 186x: 4 Free Spins
  • 200x: Random Free Spins
  • 500x: Razor reveal
  • 550x:  5 Free Spins

10. Extra Chilli Megaways (Big Time Gaming)


Min bet0.20
Max bet40
Max win20,000x
Bonus buy cost50x

Extra Chilli Megaways is one of the best all-time classics when it comes to slots offering Megaways and bonus buys.

Buying the bonus on Extra Chilli Megaways is cheaper than on most other Feature Buy slots, as it costs you 50x the bet.

However, there is more to it. This will buy you 8 Free Spins, but before playing, you can gamble your 8 spins for more. Four consecutive successful gambles will get you 24 spins, but losing the gamble during your progress can lead to 0 spins.

9. White Rabbit (Big Time Gaming)


RTP97.24% | (97.77% Bonus Buy)
Min bet0.10
Max bet20
Max win13,000x
Bonus buy cost100x

White Rabbit is another Big Time Gaming classic and the first slot offering the Feature Buy option with the set-up that we are used to.

It might not be as popular as some years ago due to increased competition from new slots, but it still holds up great.

To buy the bonus, you pay 100x, and within the Free Spins, you want to see those muffin symbols all over the place to score the big wins.

You won’t find many other slots offering such a high RTP as on White Rabbit, as it increases to 97.77% when using the Bonus Buy option.

8. Pirots (ELK Studios)


Min bet0.20
Max bet100
Max win10,000x
Bonus buy cost3x – 500x

In 2023, ELK Studios released a very different kind of slot, as it resembles something seen in a video game.

Pirots doesn’t use a standard way of winning, but instead, the four birds collect the symbols while coming across modifiers and some crazy stuff.

There are several Bonus Buy options available through the X-iter mode:

  • 3x: Spins with four times higher chance of triggering a bonus.
  • 10x: A guaranteed full symbol collection.
  • 25x: Maximum grid size.
  • 100x: Bonus Game.
  • 500x: Super Bonus Game.

If you enjoy this slot, then try Pirots 2 as well, which also offers Bonus Buy options.

7. Sugar Rush (Pragmatic Play)


RTP94.50% | 95.50% | 96.50%
Min bet0.20
Max bet100

Pragmatic Play is the expert in creating colourful and sweet-looking entertaining slots, and one of the most popular ones is Sugar Rush.

When using the Feature Buy option, you randomly trigger 10, 12, 15, 20, or 30 Free Spins.

6. Dead or Alive 2 (NetEnt)


Min bet0.09
Max bet9
Max win111,111x
Bonus buy cost66x

Dead or Alive 2 was originally released without a Bonus Buy feature in 2019, but NetEnt couldn’t resist adding the Feature Buy option to this popular western-themed slot a year later.

One unique feature in Dead or Alive 2 (apart from the huge max win potential) is that you get to choose the volatility level in the Free Spins.

Buying the bonus game will cost you 66x stake, and once triggered, you choose between the following options:

  • Train Heist – Win often (Lower volatility)
  • Old Saloon – (Medium volatility)
  • High Noon Saloon – Win Big (High volatility)

The higher the volatility, the higher the max win potential.

“Set in an underworld that is devoid of light, happiness, and hope, Darkness grabs you by the wrist and refuses to let go, as hard as you may try. It is the stuff that nightmares are made of, which is precisely the point”.

Players looking for a shortcut to the main feature can buy the Free Spins by paying 100x the bet size used to spin.

Best Casinos for Bonus Buys

Our selection of the best online casinos for Bonus Buy slots:

How do bonus buys work?

You start by clicking on the Feature Buy option. You then agree to buy the bonus and confirm the amount that will be withdrawn from your balance.

The slots bonus round or Free Spins then begins.

Win potential is the same whether you trigger the bonus organically or if you buy it.

However, in some cases, the RTP can be slightly higher on the bonus buy option than the game’s average payout rate.

Why do bonus buys in slots exist?

Bonus buys in slots were created to allow players to buy the bonus and get a shortcut to the game’s main feature instead of waiting for the bonus to trigger through the base game.

Bonus buys also exist as game studios and casinos will make more revenue faster when players buy bonuses and spend more money. 

Is it risky to buy bonuses in slots?

Buying bonuses can be highly risky, as the feature buys are costly. You need to hit one or several big wins during the bonus round to break even or profit from the bonus.

It can also be easy to get carried away and chase losses or spend more money on bonus buys than initially planned or if you would have played the slot without using the bonus buy feature.

Always decide your budget and time restrictions beforehand and stick to them while playing responsibly.

Why aren’t bonus buys available everywhere?

Although most new online slots come with a Bonus Buy option, some jurisdictions (like the UK and the Netherlands) have forbidden bonus buys to protect players from harmful gambling activities. In these countries, the Bonus Buy option has been disabled.

Certain game studios like Play’n GO have also officially communicated that they won’t add bonus buy features to their slots as they don’t see these enhancing the player’s overall experience when playing their games.

Cheapest bonus buys

In general, it’s expensive to buy bonuses in slots, but there are some slots where they can be obtained for a lower-than-average cost.

These are the 10 cheapest bonus buys available, which give you direct access to the game’s bonus game or free spins.

Top 10 cheapest bonus buys

One slot that doesn’t qualify for this Top 10 list is Fizzy Pennyslot, as the bonus buy cost is 65x the bet. However, we need to mention it anyway, as you won’t find a slot with a cheaper bonus buy as the minimum bet option starts from 0.01 per spin. This translates to 65 cents per bonus buy!

The most expensive bonus buys

On the other side of the spectrum, the most expensive bonus buys are aimed at high rollers and risk-takers who are looking for big wins while being prepared to risk significant losses.

Some of these slots offer a range of different bonus buy options in the slots, but those listed below are the most expensive ones found online today.

Different kinds of Bonus Buys

Some slots offer players the option to buy the main bonus game for a fixed amount.

Other game studios like ELK Studios offer players the chance to buy enhanced spins or the main bonus games through its X-iter feature.

These options often include:

  • Base game spins with a higher chance of triggering Free Spins.
  • Base game spins with one or several features
  • The slots bonus game
  • A super bonus game

The more win potential the feature has, the higher the cost of the bonus buy.

Other game studios that offer several bonus buy options in their slots include Hacksaw Gaming, Nolimit City, Print Studios, Avatar UX, Yggdrasil, and more.

Some game studios like NetEnt and Big Time Gaming resisted the urge to add bonus buys features to their slots for a long time, but we have now started seeing slots from these developers with feature buys as well.

Bonus buys and their future

CasinoWizard predicts that watchdogs will take action against expensive “Buy a Bonus” features at some point.

This has already happened in the UK market, where the bonus buy features have been banned.

Of course: everyone has to shoulder a level of responsibility. Amongst other things, it is your responsibility to only play with money that you can afford to lose and to stick to your gambling budget.

But things like the “Buy a Bonus” feature can increase the pressure to bet more than you were planning, as what makes the Buy a Bonus feature so interesting is that it offers players the option to get straight into the bonus rounds where the significant win potential awaits.

It always comes with a high risk, though, as it’s costly to buy the bonuses.

“Buy a bonus” will often cost you many times your usual bet. When game providers increase the pressure to buy the bonus, it could mean that “Buy a Bonus” suddenly becomes number one on all the watchdog lists.

But so far, it’s a popular phenomenon that most game studios use today on their new releases.

Frequently Asked Questions

Can you buy a bonus on slots?

Most online casinos today offer slots where it is possible to buy direct access to the slot’s main feature, a.k.a bonus game or Free Spins. However, bonus buys are prohibited in some jurisdictions like the UK.

Should I buy bonuses on slots?

Buying a bonus in a slot is risky, as there are no guarantees of winning anything from the bonus round. Therefore, it comes down to personal choice. Although a feature buy gives you direct access to the Free Spins, you need to decide if you want to take that calculated risk.

What are feature buys?

Feature buys are options in casino slots where you buy a bonus for direct access to the game’s main feature, the bonus game, or Free Spins.

How much does it cost to buy Free Spins in slots?

The cost of buying Free Spins in slots varies from 60x to 500x, while slot developers most commonly use 100x the bet.

What casinos do bonus buys?

All premium online casinos offer slots to their players with bonus buys. The options usually come down to the game studios’ willingness to create slots with feature buys and whether the jurisdiction where the casino operates allows bonus buys.

Can you buy the bonus on slots in the UK?

Sadly, no. Bonus Buys have been banned by the UK Gambling Commission. As a result, licensed UK slots sites are now allowed to offer Bonus Buy slots.
