Casinos Offering Slots with Bonus Buy Feature

Due to the popularity of bonus buy slots, finding such games is relatively easy. Still, it’s always good to stick to trusted gambling operators that also meet many other criteria. We researched and tested to handpick the best online casinos for playing slots with the buy feature.

These operators have top-class support, hold reputable licenses, and provide secure payment methods. These advantages enable customers to enjoy a carefree experience knowing that the games are fair and their possible payouts are guaranteed.

What Is a Bonus Buy Slot?

The simplest definition is – bonus buy slots are online slot machines where players can pay to trigger the bonus round. The cost varies, depending on the game and what the bonus round includes. When 10+ free spins with special symbols are involved, the cost of the bonus buy feature may be 100x your bet.

Bonus buy slots are everywhere, including traditional gambling sites, no account casinos, and crypto casino websites. The concept is perfect for impatient users who don’t want to wait hours or even days to trigger a special feature.

A bonus buy slot machine offers this option as a paid service or a side bet. Rather than playing and hoping to hit three scatters, you can buy them. This step is often a costly investment that doesn’t guarantee any returns. It’s also a shortcut to the game’s most exciting and rewarding part.

How Does the Bonus Buy Feature Work?

As the name suggests, bonus buy slots allow players to purchase the game’s unique features. Usually, to activate a bonus round right away, you need to be very lucky. Alternatively, you will need to play for a long time.

Bonus features are the most rewarding aspects of any online slot and are challenging to get. Often, triggering such features is like hitting the jackpot. That’s why generous operators with massive bonuses and cashback casinos may forbid players from playing bonus buy slots when using bonus funds.

Consumers want to experience these special rounds but are often not lucky enough. Well, with bonus buy slots, luck can be bought. In other words, the mechanic allows players to purchase the symbols necessary to trigger the bonus round.

There’s usually a Buy Bonus or Buy Feature field somewhere near the playing screen. Once you click on it, you’ll see the cost and can proceed to pay it from your playing funds. Then, another spin takes place, and the necessary scatters or bonus symbols will land on the screen. Just like that – a bonus round is activated. The bonus feature will go on as per usual. Once done, your winnings (if any) are added to your bankroll.

Here’s a step-by-step example of how bonus buy slots work:

  • Open the game.
  • Click on the “Buy Bonus/Buy Feature” button.
  • Select the bonus round you want (in case there’s more than one option).
  • Pay for the feature.
  • Get a winning spin that unlocks the bonus round.
  • Wait for the bonus round to run its course.
  • Keep playing in standard mode.

How Much Does the Buying Feature Cost?

There are no rules about how much bonus buy slots charge players for activating the unique feature. Each provider gets to decide on the price of their buy bonus offer. The range is broad because some cheaper options cost about 50x your bet. By contrast, there are buy bonus features that cost 150 times your bet or even more.

Moreover, some slots with buy bonus have multiple features on the menu and may have different costs. Such an example is Deadwood xNudge, where one feature costs 71x your bet, and another is a fantastic 750x your bet.

As there are no rules, we advise you to always check the price and understand it before purchasing the bonus round. Providers are typically transparent with the cost and show the total pricing in your selected currency on the purchasing screen.

The Takeaway & Useful Tips

Overall, bonus buy slots are a cool concept, and that’s why they’ve become so popular. Regardless of how entertaining and potentially rewarding the feature is, it can also be dangerous. Players may often feel excited to try out the bonus round without thinking about the big investment they make. Because of that, our main advice is always to respect your playing budget and never overspend.

Aside from that, there’s no reason why any player shouldn’t try this excellent mechanic. As long as you have realistic expectations and understand that winning isn’t guaranteed, you are free to enjoy the thrill of special features. Buy bonus is, in a way, like a skip-the-line ticket.
