Slots with the option for players to purchase their way into bonus rounds, which can boost the RTP and grant access to additional spins and win multipliers, are known as bonus buy slots, and they’re massively popular right now!

While these mechanics remain controversial, as titles that work this way are banned in the UK, it’s still very easy to find a bonus buy slots demo to play. These bonus buy slots free play options are widely available and great fun!

In this text, we’ll cover how these games work, which are the best, and explore some of the advantages and disadvantages. Free slots with bonus purchasing options are increasingly popular and on the rise, enabling players to bypass certain restrictions and access the bigger wins.

Demo Slots Bonus Buy – A Closer Look

Before you start playing, it’s worth going into some more detail about exactly what these games are and how they work. Many players get frustrated by having to spend a great deal of time unlocking bonuses and holding out for feature-activating spins. Essentially, these types of games give players the option to fast-forward and bypass this.

On the other hand, when playing an online slot game which allows players to buy their way into features, it’s possible to burn through bankrolls with surprising speed, and it’s quite easy to lose track of losses, which is why they have been banned by the UK Gambling Commission.

Players in the UK can still enjoy the thrill that comes with playing free demo slots bonus buy versions, and we’d highly recommend giving it a try!

The Concept of Bonus Buy Slots

The concept of Bonus Buy Slots has undergone a remarkable evolution, transforming from a novel idea to a prominent niche within the realm of online slots. Originally, only a handful of slots provided players with a direct pathway to the bonus round. However, this unique feature has now become a standard expectation for enthusiasts of online slot gaming.

In the current landscape, it’s almost surprising when new slots are introduced without the option to purchase the bonus feature, showcasing the significant strides this genre has made. Slotozilla’s team prepare Bonus Buy Slots Timeline to trace this evolution:

• 2017: Big Time Gaming pioneers the concept with the release of White Rabbit, the first online slot machine with a buy feature bonus.
  The cost to trigger the free spins is set at 100 times the bet.
• 2019: The UK Gambling Commission intervenes and bans the bonus buy feature for players in the UK, reflecting regulatory adjustments.
• 2021: Nolimit City introduces San Quentin, featuring a buy option for the bonus, with a substantial cost of 2,000 times the bet.
• 2022: The Bonus Buy trend gains momentum, with over 300 games now offering players the option to purchase bonus rounds.
• 2023: Blueprint Gaming innovates further, integrating the Build a Bonus feature into Buffalo Rising Megaways, allowing players to buy into the bonus round at a maximum cost of 7,378 times the bet.

This timeline encapsulates the dynamic evolution of Bonus Buy Slots, highlighting key milestones that have shaped this popular and engaging facet of the online slot gaming experience.

Factors to Consider When Selecting a Bonus Buy Slots Demo

Tempted to give one of these slots a spin? Well, there are a couple of things that are worth considering first. To help you make the most informed decision of which game is right for you, have a think about these six factors:

• The buy-in features: The bonus buy feature types can vary significantly. Some of them effectively boost the overall RTP, unlock new rounds within a game, or enable scatters or win multipliers.
• The game’s theme: Slot titles are most enjoyable when they are based around a theme which speaks to you. Do you like darker horror themes? Or gemstone-hunting adventures?
• RTP rates: These dictate how much of the stake, on average, is returned to the player and how much the house edge is. Around 96% is considered fairly typical.
• Volatility: This will be mentioned in the slot’s details, but it will be expressed as high, medium, or low. A high-volatility game won’t pay out very often, but when it does, the winnings will be much larger.
• The developer: Some developers are known for making games with the option to buy into bonus features, so you may wish to start here.
• The casino: Not all slots can be played at all casinos, and casinos can vary hugely in their quality, so be sure to choose a good one.

When choosing which buy bonus slots UK to play, take a look at the Slotozilla experts’ list on this page.

Mechanics of Bonus Buy Slots Free Play

Playing a demo slots buy bonus will obviously mean that you can’t win real money, and this is the way it will be for UK players. Whilst you can’t play for real money in the UK, you can enjoy great demo versions of the games, which are still thrilling.

Buying into a bonus feature costs an amount relative to the stake, expressed as ‘times/x’. For example, a bonus round may be guaranteed for 50x the stake, or win multipliers may be activated for 100x the stake.

Some lower-priced games offer bonus purchasing features for just 5x, whereas others may cost thousands of times the stake. It’s easy to see how the costs can quickly stack up, so wager sensibly.

Buy Bonus Slots UK Variations

Some slots that have bonus purchasing options are very different from others. Whereas some are extremely simple, others can be rather complex when it comes to using them. It’s crucial that players understand these differences, especially if there’s actual cash on the line! To that end, here’s an overview of the most common variations of these features:

• High and low volatility offers: Some games offer multiple buy-in features, enabling them to accommodate different types of players. These may be divided between the riskier but potentially more rewarding ones (high volatility) and the safer ones (low volatility).
• Increased potential wins: Some of these bonuses grant a temporarily increased max win or a win multiplier, which can give huge boosts to your winnings but may also be quite costly to activate.
• Free spins: It’s common for these games to offer a bonus which unlocks a stream of free spins back to back. These enable players to keep playing, filling the metres and accumulating multipliers.
• Token accumulation: This refers to a bonus feature which only a few games have. It essentially gives players the chance to earn free entries over time, encouraging them to keep spinning at an increased bet amount.
• Bonus rounds: These are fairly common in comparison to some other types of buyable bonuses. These enable players to activate a bonus round feature of the slot game in question without having to wait for it to activate naturally, saving time and frustration.
• RTP boosts: Some increase the return to player rate temporarily, increasing it by just a couple of percent, but this can have the effect of giving these games some of the highest RTPs of any title out there.

Top 5 Slots Bonus Buy Demo to Play

With the ever-increasing popularity of these types of games, we wanted to direct players to the best! More and more bonus buy feature slots are landing on casinos all the time, and not all are equal, so it’s important to be able to separate the best from the rest!

As always, you can trust that the Slotozilla experts know their stuff. In this section of our guide, we’ll walk you through our favourite 5 slots with buy bonus options to help you decide.

Slot name	Provider	RTP	Max Payout	Buy Bonus Cost
Money Train 2	Relax Gaming	96.4%	50,000	100x your stake
Gems Bonanza	Pragmatic Play	95.54%	10,000	100x your stake
Stack ‘Em	Hacksaw Gaming	96.2%	10,000	129x your stake
Starburst XXXtreme	NetEnt	96.26%	200,000	95x your stake
Chaos Crew	Hacksaw Gaming	96.3%	10,000	129x your stake

Money Train 2

This popular title from Relax Gaming takes place in a thrilling Wild West world, where players will have to fight to survive. With some top graphics and effects, this game is amongst our favourite bonus buy slots UK titles out there.

Money Train 2 features 40 paylines, 5 reels, and 4 rows. Players can win by matching symbols such as hearts, clubs, diamonds and spades. The RTP rate is a respectable 96.4%, and the volatility is high. So, while players may not encounter frequent victories, the wins are significant.

There are plenty of bonus features in the game, such as the activation of the bonus round. Two scatter symbols will activate a re-spin, and three scatter symbols unlock free spins. Multipliers accumulate and multiply the bet until the player is out of moves.

The per-spin value can be anywhere from ￡0.10 to ￡1,000, and the potential payout is 50,000 times the stake, meaning that some seriously big wins are possible.

Gems Bonanza

With its relatively high RTP rate of 95.54% and max win of 10,000 times the stake, Gems Bonanza is yet another fantastic slot from the experts at Pragmatic Play. It makes use of the endlessly popular gemstone theme, which can be found across a range of titles, combined with desert treasure-hunting vibes.

The slots buy bonus feature gives players access to the Gold Fever round for 100x the current total bet. Gold Fever is a five-tiered bonus round that allows players to access win multipliers, beginning with 2x multipliers on tier 1 and ending with a very generous 10x multiplier on the 5th tier.

Different coloured gemstones have different effects on the symbols around them. For instance, blue gems will explode everything nearby, whilst red gems grow and expand into the spaces around them.

By combining a top win with some good luck on the slots bonus buy round, it’s possible to achieve some serious wins.

Stack ‘Em

A relatively new release from the Hacksaw Gaming company, Stack ‘Em already has a loyal following of fans who keep coming back for its fun theme, likeable characters, and many win multipliers.

Beneath its simple aesthetic and calming countryside setting, this game boasts a 96.2% RTP and runs on a 5×6 grid. The max win is 10,000 times the stake, and the volatility is high, so lucky players may well be able to beat the odds and walk away with some hefty sums of cash.

The minimum bet is ￡0.20, which is a little higher than some other slots, and the maximum bet is ￡100. The symbols include a snake, a skull, a thumbs-up symbol, a leaf, and various letters.

In terms of the feature buy option, players can fork out 129x their current bet for instant access to the bonus round. Also, each successful spin is rewarded with one re-spin, so it’s possible for lucky players to just keep spinning! The bonus round can unlock multipliers, which, when combined with some cluster pays, can be really quite generous.

Starburst XXXtreme

A bonus buy slots version of NetEnt’s classic title Starburst, Starburst XXXtreme gives players the opportunity to buy their way into the bonus round. This game has a 5 reel format and 9 paylines, and the RTP is 96.26%, which certainly isn’t bad.

Because it’s such a highly anticipated sequel to the infinitely popular Starburst, this demo slots bonus buy version of the title has gained huge popularity.

Starburst XXXtreme offers players the opportunity to purchase certain perks, which will increase their chances of hitting a big jackpot. The new version of Starburst has a 150x multiplier, which is associated with the expanding wild symbol, and it’s possible to receive a huge payout of up to 200,000 times your stake!

In terms of other bonus buy options, paid extras include a guaranteed wild symbol for each spin when staking 10x your initial bet. And 95x your bet will unlock two jokers with each spin. These bonuses will arrive naturally, or the player can opt to pay extra to guarantee them.

Chaos Crew

With its dark, gothic punk theme and a vivid, hand-drawn interface, as well as one of the highest max wins out there, Chaos Crew is one not to be missed! The above-average RTP of 96.3%, the exceptionally high volatility, and the optional features work together to make this game potentially very profitable.

The wild symbol bonus feature works in a traditional way and can grant players with some nice little win multipliers, but it can be activated through a bonus buy slot method, paying extra to guarantee their activation. Free spins are triggered by three scatter symbols, which can also be purchased. Multipliers accumulate until all spins are exhausted and then totalled up.

The design of this bonus buy slots title is great fun for those who aren’t afraid of the dark! It contains spooky symbols such as monsters and skulls, in addition to creepy items like rotting apple cores and moths. By collecting at least three matching symbols, players can release some great wins.

Pros & Cons of Demo Slots Buy Bonus

There’s lots to love about demo games. They enable you to try new titles for free but not play for actual money. Here’s a summary of the pros and cons of casino slots buy bonus titles.

• Slots with bonus buying options give players the opportunity to unlock elusive features and rounds

• Playing bonus buy slots can be more thrilling than regular slots, with as much access to extra features as the player wishes to buy

• Slots become a faster-paced and more exciting experience when playing bonus buy titles

• The potential winnings, if wagering with real cash, are greatly increased

• It can be costly to keep triggering bonus rounds when using slots that have bonus buying features, so players may lose track

• Extra rounds add to the addictive nature of these games, so it’s even more important that players are able to exercise self-control and gamble responsibly

• These are banned in the UK, so players will only be able to use slots bonus buy demo versions and not win real money

Increasing Your Winning Potential With Bonus Buy Feature Slots

When gambling, there’s never any guarantee of a win. That said, there are a few good practices that players can follow to ensure that they’re giving themselves the best possible chance when playing buy bonus slots:

• Read the rules: Ensure that you’re fully aware of how much each bonus feature costs and exactly what it unlocks.
• Look at the pay tables: These let you know what each spin outcome is worth so you can determine whether or not it’s worth spending extra cash to boost it.
• Use multipliers when you’re winning: If you have the option to spend multipliers when you choose, don’t waste them on smaller wins.
• Choose high RTP titles: These offer the best returns of your stake.
• Look at the volatility: A high-volatility game will pay out larger wins but less frequently, so use that to your advantage.
• Play demos first: This is a great way to understand the mechanics before spending.
• Enjoy yourself: One of the advantages of bonus features is that they add to the thrill of the ride, so be sure to have fun.

Risks of Casino Slots Buy Bonus

There are a couple of reasons why bonus buy slots UK are controversial. It’s very easy to get carried away and end up spending more than you can afford to lose, which is not responsible.

Whilst the RTPs of these titles are generally quite high, and using feature buy slots options smartly can even increase the overall RTP, a single streak of bad luck can completely deplete a huge balance in a very short amount of time.

Always keep an eye on your bankroll to ensure that you aren’t suffering heavy losses, and if you’re not having fun, take a break.

Top 5 New Bonus Buy Slot Games

As we briefly mentioned above, these titles are very popular, and there are constantly new ones being released. Most developers offer their own bonus buy slots UK players can enjoy (even if only in demo mode), so here’s an overview of what’s brand new:

Innovations & Emerging Trends in Slots With Buy Bonus

Despite the controversies stirred up in some territories because of the speed with which players can lose money, slots buy bonus UK options are rapidly growing in popularity, with more and more coming out each year.

With their numbers constantly increasing, it’s no surprise that review demo versions of these games have become widely played. These enable players who cannot access buyable bonuses, such as those based in the UK, to enjoy the thrilling experience these games have to offer. The rapid growth in this sector of the gambling industry is indicative of what players want, and it shows no sign of slowing.

Game Providers of Slots Bonus Buy

There are certain developers and providers of slot games which have emerged in this particular field, producing a stream of popular bonus-buying titles for players to enjoy.

• Playtech: Playtech is a giant of the gambling industry, known for its vast range of slots and a great track record of success. Established in 1999, it has produced some of the world’s best-known titles.
• NextGen Gaming: Another big player in the world of online slots, NextGen Gaming produces some high-quality games with high RTP rates and has been keeping players happy for many years!
• Stakelogic: Founded in 2015, Stakelogic is a relatively new company, but they’ve made a big splash with their buyable bonus slots games and now have a library of more than 100 titles.
• Reel Kingdom: With the success of their winning Big Bass Splash series, Reel Kingdom has expanded into slots which allow players to buy into feature rounds.
• NoLimit City: Specialising in high volatility slots that have decent RTPs, this 2014 company makes some extremely engaging games.
• AvatarUX: Boasting many high-performing games with huge max wins, AvatarUX makes a number of popular titles, such as CherryPop and PiggyPop.

UK Slots Buy Bonus Games: Are They Worth It?

Because of random number generators, there’s no way to accurately determine whether it’s worthwhile buying into a particular feature. Some bonuses can be unlocked by paying 100x of your stake, but there’s still a high chance that you won’t win anything back. Even when a bonus promises to boost your RTP, there are no guarantees.

If a slot feature is activated by approximately 1 in every 50 spins, and the cost of activating it is 40x the stake, it may be worthwhile, but you can’t be sure!

Unlocking Slot Bonus Rounds: A Note for UK Players

The allure of slot bonus rounds is undeniable, prompting some players to consider paying to activate these enticing features. However, it’s essential to note that, unfortunately, the option to buy bonuses, known as Bonus Buy slots, is not accessible in the UK. This restriction stems from the UK Gambling Commission (UKGC) imposing a ban on this feature in 2019.

Nevertheless, UK players can still indulge in playing these Bonus Buy slots, albeit without the ability to pay for the privilege of triggering the Bonus Round. While the purchase option may be restricted, the gameplay remains enjoyable.

For those curious to explore recently launched slots equipped with the Bonus Buy feature, it’s worth noting that these games are available in other parts of the world but not in the UK due to regulatory constraints. Nonetheless, UK players can still experience the thrill of these slots without the purchase option. Check out the following recommendations for some of the latest slots and enjoy the exciting gameplay they offer!

Payments for Slots Buy Bonus

If you’re playing a UK slots buy bonus version rather than a demo version, you’ll need to think about how you’re going to fund your account.

Payment System	Description	Countries That Allow	Withdrawal Processing Time	Supporting Casinos
Visa Debit	A simple way of transferring cash directly from your bank to your casino	Widely available	2-5 days	All casinos
Mastercard	This works the same as Visa Debit cards	Widely available	2-5 days	All casinos
PayPal	The most popular and widely accepted e-wallet.	Works in 200+ countries and supports 25 different currencies	2-5 days, but sometimes less	Many, including Wizard Slots, Yeti Casino, etc.
Bank Transfers	Bank transfers are slower but safe and direct	Widely available	5-10 days	All Сasinos
Credit Card	A way of borrowing money, these may end up costing interest	Popular in some countries but banned in the UK	4-7 days	Not accepted in the UK
Cryptocurre ncies	Cryptocurrencies are accepted by a growing number of businesses, including casinos	They are largely unregulated, so they’ll work in most countries	Very fast, sometimes instant	A small but growing number, including NetBet, Fun Casino.

Deposit & Withdrawing With a Slots Buy Bonus UK

Deposits are generally instant, although there may be one or two exceptions to this. In the case of the most popular payment methods, such as debit card payments and e-wallets, you can expect to see that cash in your account right away.

Withdrawals, however, take longer. Again, it depends on the chosen banking method, but most take at least a couple of days before your winnings hit your bank account. Withdrawals can only be made from a verified account, which means that you’ll have to submit evidence such as a passport copy.

Making a deposit is easy. Just log in, then look for the ‘Deposit’ or ‘Wallet’ link and follow the instructions. Enter the amount, select a payment method, and that’s it! Withdrawing is similarly straightforward.

It’s also worth noting that all banking can easily be arranged from your mobile device. Modern portable devices such as smartphones are highly powered, so there’s virtually no compromise at all when accessing a casino from your mobile.

Final Thoughts About Buy Bonus Slots

These games allow players the opportunity to buy their way into the features which regular slot titles make you wait for. This can save time and frustration but may prove expensive, which is why they have been the subject of controversy. Players should always gamble responsibly and exercise additional caution in the case of these games.

There are plenty of options for players to choose from, and the best are made by some top developers. Examples of features which can be purchased include access to bonus rounds, free spins, and win multipliers.

Slots where you can buy bonus UK features are banned by the United Kingdom Gambling Commission, whose concern is that players may lose track of their funds, which is easily done with these variations of the traditional slot. However, for UK players, there are always trial/demo versions of free slots bonus titles, which can give you a taste of the fun without the risk!
