Bonus Buy Slot Games Online

Bonus Buy slots or online slots with Buy Bonus features have become a standard in iGaming. A serious number of new releases per month come out with an integrated Bonus Buy option, and it seems players are turning towards such games more than ever.

In case you are looking to explore Buy Bonus games and check out the best Bonus Buy slots online, our guide below is here to help. We also provide a cool selection of top-rated online casinos where you can play Buy Bonus games.

What Is the Bonus Buy Option?

Simply put, Bonus Buy (or Buy Bonus, or Feature Buy) slots are online slots with the Bonus Buy feature. This feature is an add-on that allows players to purchase the Free Spins bonus round.

In other words, you don’t have to wait for Scatters to unlock Free Spins, you can simply pay to unlock it. That’s it, it’s quite simple – you click on a button, pay the required sum, and then enjoy bonus spins without a worry on your mind.

But why are such games so popular?

The answer lies in the popularity of Free Spins. Free Spins are typically the main and most attractive booster in a game, and so all players want to unlock them. However, that’s noy always easy. Namely, most punters have to wait for many spins before they are lucky enough to get to bonus spins. But an option to cut that wait to nothing and simply waltz into Free Spins is too good to be passed up.

That is why Bonus Buy slots are so popular. But there are some bad sides to these games.

Namely, several competitive gambling markets are against this add-on concept as it is considered potentially harmful for the players. Essentially, some punters are ready to pay big sums to enter Free Spins, and so gambling institutions and authorities were concerned fans and players might abuse this option and potentially bring harm to themselves. The only appropriate response they’ve found is an outright ban of the functionality. Slots that do have it are required to turn off the option for players in specific markets, such as Ireland and the UK. In other words, if you live in the UK, you cannot experience Feature Buy options as they are not valid in  your market.

Big Bass Splash (Pragmatic Play)

Big Bass Splash Pragmatic Play

Big Bass Splash is a Pragmatic Play fishing themed video slot. It’s actually part of a large series of slots currently comprised of 10+ Big Bass slots. It all started with Big Bass Bonanza, but it was quickly followed by Big Bass Bonanza Megaways, Christmas Big Bass Bonanza, etc. The latest release is the Big Bass Christmas Bash video slot, but crash game fans will also enjoy the Big Bass Crash™ game as well.

In Big Bass Splash, players meet the 5×3 grid with 10 fixed paylines. One thing about it is the high RTP rate of 96.71%, but since volatility is high, it’s not something you can easily get a hold of. Wins in Big Bass Splash go up to 5,000x the stake, but worry not – you will get to reel in many other surprises as well. Some of the game features included in Big Bass Splash include nudges, Multipliers, Re-Triggers, Free Spins, and more.

Dog House Megaways (Pragmatic Play)

Dog House Buy Bonus Pragmatic Play

The second game on our list is another one of Pragmatic Play slots. This time, we are leaving fishing ponds and transferring to the backyard – or more precisely, to the dog house. Dog House Megaways is the second Dog House slot that Pragmatic Play released, as a year before the release of Dog House Megaways the original Dog House came out. There are two others Dog House slots, but only this one and the Dog House Multihold™ come with the Buy Bonus option.

Deadwood (Nolimit City)

Buy Bonus Deadwood Nolimit City

We are big fans of Nolimit City and their slot games. Themes covered in their games are fantastic, the visuals are mesmerizing, and the features showcase the creativity and win mentality of the entire team. Deadwood is perhaps one of the best examples of top-performing Nolimit City video slots with amazing game boosters and features. Buy Bonus is our focus, but there’s so much happening on-screen that you will forget Buy Bonus options exist when you lay your eyes on Deadwood.

First of all, this is a Western-themed video slot, so expect gunslingers, sheriffs, guns, and dusty saloons. It’s a 2020 release, so it’s not exactly new, but it’s one of the best Feature Buy games online even today Here are just some of the game features you’ll encounter in Deadwood: Hunter xNudge Wild, Shoot Outs, Gunslinger Spins, Hunter Spins, and Feature Buys.

Dead or Alive 2 (NetEnt)

Dead or Alive 2 NetEnt Buy Feature

Another day, another Wild West slot on our Buy Bonus slot list. This time, we are going over to the NetEnt realm, where Dead or Alive is burning hot with its sequel. Dead or Alive 2 is a fantastic adventure for all veteran NetEnt fans who enjoyed their work before the Evolution switch. For all intents and purposes, it’s an essential game to play online for real money, even if you aren’t into NetEnt.

As you can see, it’s a sequel to the 2009 classic. Train Heists, Old Saloons, and High Noon are the main game features, all of which are unlockable in the Buy Bonus and non-Buy Bonus game versions. You will also be pleased to know that win potential greatly surprises all games on this list – you can win up to 111,111x the stake in Dead or Alive 2! The first version of this game came out in 2019, but NetEnt added the Buy Bonus version a year later.

Book of Inferno (Quickspin)

Quickspin Book of Inferno Buy Bonus Slot

Hell might be a horrific place full of disgusting and horrifying things, but it’s also a great source of inspiration for game-makers. There are hundreds of online games focusing on the gods of the underworld, but none quite hit the mark as Book of Inferno by Quickspin does. This 5-reel slot wonder is a horrifying walk through fiery depths of Hell aided by a slew of game features.

Some of the main game boosters in Book of Inferno are Marked Symbols which expand to cover entire reel. If the Book lands in a Marked spot, you get a Symbol Upgrade, and that can go on until you get only the highest of wins. Free Spins are the focus of the game, as always. If you want to kickstart the adventure without Scatters, use the Buy Bonus feature that costs 125x the stake and get into Spins faster. The game has a 96.15% RTP, high volatility, and a 5,846x win potential.

Big Bad Bison (Big Time Gaming)

Big Time Gaming Big Bad Bison Slot

Big Bad Bison is another 2023 release on this list (we cannot help but add newer game as 2023 has been filled with outstanding Buy Bonus slots). It’s a Native American-themed slot focusing on wildlife in the plains. If you are into this theme or enjoy Big Time Gaming online slots, then by all means, enjoy Big Bad Bison.

Big Bad Bison online slot is a 6-reel video slot with Megaways. That means that the number of rows can fluctuate between 2 and 7, as each reel can contain a different number of icons.

Bets go from $0.20-$20, which is a lower betting range than usual. You can acquire 12 Free Spins for only 50x the stake by tapping the Win Exchange option.

Expansion! (Betsoft)

Betsoft Bonus Buy Expansion Slot

Aliens, aliens, and more aliens is the shortest and easiest way to describe Expansion! by Betsoft.
