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.

Deadwood (Nolimit City)
We are big fans of Nolimit City and their slot games.

Dead or Alive 2 (NetEnt)
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.

This 5-reel slot wonder is a horrifying walk through fiery depths of Hell aided by a slew of game features.
