❓ Do bonus buys have higher RTP?

Yes, in most cases, the theoretical RTP increases upon activating a bonus buy feature. However, this is not a drastic increase and doesn’t guarantee profit.

❓ Can you buy bonus when playing with cryptocurrencies?

Yes, the currency you use doesn’t affect the availability of a buy bonus feature. Of course, the possibility of playing with crypto depends on the accepted payment methods at the chosen online casino.

❓ What is the best provider for feature buy slots?

❓ What is the best bonus buy slot?

❓ Is it worth buying bonuses on slots?

If you want to try the bonus features without delays, buying bonuses on slots is worth it. Also, when the bonus round is activated, you increase the chances of hitting big wins, and the RTP goes up. However, profit isn’t guaranteed, and you may end up winning nothing or less than you’ve invested in purchasing the special feature.

❓ Can you buy super bonus on slots?

Some slots let players purchase super bonuses, but only when such bonuses are part of the game. If such an option exists, it will be clearly visible on the playing screen.

bonus buy logoBonus Buy Slots Explained

When it comes to bonus buy meaning, it’s the categorization of slot games that let users purchase the bonus round. Over 90% of modern slots have special bonus rounds, but this doesn’t mean that all of them are bonus buy slots.

best bonus buy casino in slot slots list demo

The simplest way to define them is to think of online real money slot games with a separate bonus buy option. Typically, slots with bonus buy have a button on the main screen that leads players to a new pop-up window where they can activate one or more of the bonuses in the game. This happens once you pay a specific amount of money.

In other words, bonus buy slots have a side bet that costs more than your current regular bet and instantly activates the special feature in the slot. By contrast, regular play means you must land the necessary symbols to trigger the special feature.

The bonus buy in slots is a perfect solution for impatient players or users who prefer bonuses over regular gameplay. Of course, this is for players willing to pay more to get these extras because the option doesn’t come cheaply.

bonus buy logoFeature Buy Cost

Every bonus buy slot is unique, so we can’t talk about a universal feature buy cost. Yet, if we analyze most of the feature buy slots, we’ll realize that any option that lets you purchase a bonus round for less than 50 times your current bet is excellent. By contrast, those who require 150 or more times your bet aren’t that good options. Most bonus buy slots require 50 to 150 times your stake, but some cost even more.

While discussing the cost, we should also note that many titles will let you pick one of the several solutions. This makes sense because, in most cases, you can launch rounds of free spins and these releases have several variants. For instance, you may choose between 15, 20, or 25 free spins; their number is based on the number of triggering symbols. So, you can use two, three, or more bonus buy bets of different costs.

Some examples of bonus buy feature costs are listed below to give you more context:

  • Money Train 2 has a Money Cart feature that costs 100x your bet.
  • Deadwood xNudge has a high-volatility free spins feature with guaranteed wilds that costs 71x your bet.
  • Deadwood xNudge has another Shoot Out bonus buy feature with extreme volatility and a sticky multiplier that costs 750x your bet.
  • Iron Banks lets you trigger 10 spins with expanding wilds for 100x your bet.

bonus buy logoWhy People Buy Bonus on Slots?

People buy bonuses on slots because they don’t have the patience to wait for the game to activate a special feature “naturally.” Sometimes it takes just a few spins to trigger free spins or a mini game. Yet, in most cases, you will need dozens of spins to achieve this goal. When you use slots with bonus buy, you can launch one (or more) of the bonuses right away.

Of course, the most common way to get rewarded in these titles is by landing winning combinations of regular symbols. However, the big wins are usually reserved for the bonus features, and that’s where the bonus buy feature comes into play.

bonus buy logoBest Bonus Buy Slots

The popularity of bonus buy slots is growing, which is why we now have hundreds of these releases. However, only some can be labeled as the best bonus buy slots. To help our readers, we have created a list that includes the most exciting titles belonging to this category.

bonus buy logoPragmatic Play Bonus Buy Slots

Happy Hooves

Thanks to Happy Hooves, players are taken to a stable where they can find some of the finest horses in the world. This game has a standard matrix of 5 reels and 40 paylines. It also has special wilds that replace specific regular symbols.

The most important feature is the Powernudge feature with respins and multipliers that can bring significant winnings. Instead of waiting for three or more scatters on the reels, players can use the bonus buy feature of this title to access the respin feature. In this case, the cost is 100x the current total bet which is more or less within the industry standard. Once they make the transaction, the round starts right away. This is definitely one of the best Pragmatic Play bonus buy slots.

Magician’s Secret

The bonus buy slots list continues with another title from this fantastic provider – Magician’s Secret. Those who love magic and witchcraft will like the story of this game. The same goes for players who prefer releases with sophisticated graphics. Technically, you’re looking at a slot with a complex layout with 6 reels, 4 rows, and 4,096 ways to win.

magician's secrets pragmatic play bonus buy slots

Of course, the best feature in Magician’s Secret is the round of free spins. Players can choose two types of free spins before the round begins – one with expanding wilds and another with sticky wilds. What about those that don’t want to wait for the bonus to activate “naturally”? Well, they can use the bonus buy button on the left, pay 100 times their stake, and trigger it that way. The good thing is that they will still get to pick one of the two modes.

bonus buy logoHacksaw Gaming Feature Buy Slots

Hand of Anubis

The list of best feature buy slots includes titles from Hacksaw Gaming too. This Malta-based brand boasts almost thirty titles with this option, and Hand of Anubis is one of the most popular among them. The theme of this game might be ancient, but this is a modern slot. You can tell that by checking at the cluster pay mechanic and the 6 reels present here. Also, you can expect attractive detailed visuals and an RTP of 96.24%.

Like in many other games, Hand of Anubis has a bonus mode in which you can choose one of the two options. They are basically free spin rounds with unique features: win multipliers, bonus icons, modifiers, etc. Regularly, players need three or four free spin icons to activate the bonus. However, with the buy bonus button, they can do this instantly. This time, the cost is a bit higher than usual, but these are very high or high free spin modes which promise a chance for good payouts. Users must pay 129 or 200 times their stake to access one of the two modes.

Alpha Eagle

With Alpha Eagle, you’ll visit a mountainous region during the winter period and meet many wild animals, including a majestic eagle. Besides the great theme and memorable graphics, this release by Hacksaw Gaming also has an above-average theoretical RTP of 96.26%. As for the layout, you get a standard 5×4 grid with 20 fixed paylines.

This title also has an excellent bonus department with several bonuses, including the Stack’N’Sync feature, Golden Stack’N’Sync, Free Spins, and Eagle Link. The best part is that Alpha Eagle has a buy bonus option that lets you choose one of four bonuses and pay for activating any of these unique features. Remember that the first two paid solutions (Bonus Feature Spins and S’N’S Feature Spins) will only increase the chances of triggering bonuses. The other two (Free Spins and Eagle Link) will start the corresponding extras immediately. They require 100 or 200 times your current bet, respectively.

Mystery Motel

Fans of mystery will probably like this product of Hacksaw Gaming. The Mystery Motel slot features visuals that remind us of fun, classic comic books. Instead of standard paylines, the game provides 1,024 ways to win, but it still has 5 reels, typical for modern slots. We should also note that the theoretical payout percentage of 96.3% is pretty solid.

As for the bonuses, the ultimate reward you can get is access to the bonus wheel by landing at least three scatter icons on the layout. Such a combo leads players to a bonus wheel that delivers a multiplier applied to the bet, free spins, or an arrow. The arrow provides another spin on the bonus wheel with higher potential prizes. The free spin mode we mentioned can also be accessed with three or more free spin icons on the reels. Every user can launch 8, 12, or 20 free spins. Another way to activate the bonus game or free spins is to click on the buy bonus sign on the main screen. The costs for these special features are 58x (bonus game), 105x (12 free spins), or 175x (20 free spins) your current stake.

bonus buy logoNoLimit City Bonus Buy Slots


Reviewing the top bonus buy slots without mentioning Deadwood would be a huge mistake. This Wild West-themed title by NoLimit City has excellent graphics, including polished theme-related symbols in various colors. The game also has an amusing matrix with 5 reels with a different number of rows and provides 576 ways to win. Also, on the technical side, we should note that the RTP is 96.03%.

Like many other NoLimit City slots, Deadwood also includes several unique features. For instance, it has multiplier, expanding wilds. There’s also a Shoot Out feature that turns some symbols into wilds. As for the free spins mode, activated with three scatters, you can pick gunslinger spins, or hunter spins with guaranteed wilds, multipliers, and other extras. Clicking on the yellow start lets players activate free spins whenever they are ready. The regular free spin mode costs 71 times your bet, while the boosted version requires a stake worth 750 times your current wager.

Bonus Bunnies

You can tell from the name of this game that it’s rich in bonuses. Bonus Bunnies has a classic farm story involving veggies and rabbits. This is another title from NoLimit City with medium-to-low volatility and a theoretical RTP of 96.14%. Players have an opportunity to enjoy great visual elements and a fun reel set of 4 reels and 30 fixed paylines.

The best, as mentioned before, are the bonuses. Even though the presence of a wild icon in this release is not something out of the ordinary, this wild symbol spreads vertically and/or horizontally when bonus icons are around. On the other hand, three or more bonus icons will launch three spins played with special icons and boosters. Impatient players can always use the yellow star on the left and activate free spins instantly by paying 60 times their stake.

Fire Hopper

Fire Hopper is a name that might lead you to think of different things, but it’s actually an online slot about a fiery frog living a happy life in a big pond. The game by Push Gaming has an attractive 7×7 grid and relies on the cluster pays mechanic. It also has a reasonably high RTP (96.3%) and high volatility.

What’s even better is the presence of several icons with special properties and a round of free spins. The latter is won when the frog icon collects a bonus firefly symbol. You should expect a round of seven free spins. Since this release is on our list, you know that you can also purchase the bonus, and in this case, it will cost you 124 times the base bet. Players can access this feature with the help of the star symbol above the play button.

Big Bamboo

Another slot worth highlighting in this category is Big Bamboo, the title that brings the beauty of a bamboo forest to your screen. Even though it has the standard 5 reels, this release also has 6 rows and 50 non-adjustable paylines. Once again, we have a title with a slightly higher RTP – 96.13%.

The regular way to activate the free spins feature in Big Bamboo is to land the gamble scatter in the base game/golden bamboo feature, and the game scatter reveals a free spins prize. The good news is that you can expect various boosts that can help you get big wins during this round. If you don’t want to wait for the combo that triggers this bonus, use the star, and pick one of the displayed options worth 99 to 608 times the bet.

bonus buy logoMoney Train 3 Bonus Buy

Money Train 3 is part of the exclusive Money Train series created by Relax Gaming with a sci-fi/futuristic theme. You can expect several bonuses and extras in this game, including a Money Cart bonus round. It’s a round of free spins with special icons promising cash rewards. Every player can choose one of the four rounds with specific behaviors with the help of the Buy button (railroad switch lever).

money train 3 best feature buy slots relax gaming

First, the persistent feature, which costs 500 times your stake, provides a bonus game with one persistent symbol. Then we have the original feature that requires 100 times your bet, activates the bonus game, and vouches to reset the spin count to three for every newly landed symbol. The two-spin feature costs 50 times the stake and resets the spin count to three, while the one-spin feature requires 20 times your bet and resets the count to one.
