Slot machines are probably the most popular type of online casino games. Thousands of titles are already available for players, and software providers keep on supplying new exciting releases. They follow trends and attract gamblers with interesting designs and features. One of the most exciting features they’ve developed is the opportunity to purchase some special symbols and rounds. The slots with such an in-built option are clustered in the category of Bonus Buy games.

Bonus buy casino games on a par with progressive jackpots and other featured slots are real hits on online casino sites. Diverse designs allow them to satisfy all preferences, different numbers of paylines and reels make them suitable for different betting styles, and various special features let everyone find something to their taste.

Nonetheless, feature buy slots have one more significant advantage: they allow you to purchase bonus rounds and enjoy a game with a load of benefits. This opportunity has made them trendy.

Many of the bonus buy slots become our players’ favorites and get into the list of Loki top casino games. This proves once again that this casino game type is high-quality, engaging, and profitable.

Slot machines differ in visual themes, animation, sound effects, and the number of reels and rows. More significant particularities include the number of paylines and sets of features. In most cases, these features can be divided into two categories: special symbols and in-game rounds.

Special symbols

Special symbols are a large group of icons that activate different in-game bonuses. Thus, wilds substitute regular symbols, expanding and big ones are worth several icons, and scatter and bonus symbols launch bonus games. Software providers may come up with other features or combine two or three symbol types in one icon.

In-game rounds

In-game rounds include bonus games, free spins (which are often a form of bonus games), and risk games. Bonus games provide players with an opportunity to win big practically without effort. These mini-games are rich in special symbols, bet multipliers, and other benefits. Free spins are a bit less original than other bonus rounds, but they give you the same perks and allow you to play for free.

Risk games differ from the previous two in-game rounds. Their aim isn’t to get additional winnings but to increase the current ones. In other words, while bonus games are activated by special symbols and give you a chance to get impressive wins, risk or gamble rounds launch after you get a prize and allow you to maximize it. Though, it’s a part of a gambling game, so a winning reduction is also possible.

It is the in-game round feature that makes bonus buy slots so special. The point is that players can just purchase these rounds in feature buy games, meanwhile you have to wait for them to drop in the regular slot machines, and there is no chance to accelerate the process and satisfy the longing. However, when we say that you can obtain an in-game round, we mean only bonus mini-games and free spins. Risk games are activated as usual — by hitting a win.

As for other features, there is no difference between bonus buy and other slot types. You can enjoy multiple visual styles and special symbols in hundreds of titles created by different software providers.

The Loki casino is proud of its fantastic game collection, which includes more than 6,500 titles of different genres like roulette, poker, blackjack, and slot machines. Sure, we have a nice catalog of slots. You may find your favorites among over 900 bonus buy slot machines. Naturally, there are some popular options in this list.

The top 5 feature buy games in our online casino are:

1. Foxi Wild Heart

This romantic slot created by BGaming consists of 5 reels and 4 rows. Free spins, 4 special symbols, sticky wilds, a Wild Frames feature, and an extra multiplier are included in the gameplay of this 20 payline slot. Gamblers can buy a bonus round of one of three levels: regular free spins, those with 2x2 wild symbols, and a bonus game with 3x3 wilds. Foxi Wild Heart game has 92.03% RTP.

2. Max Miner

It’s a 5x3 slot which takes the player to a gold mine. Scatter and wild symbols are available for lucky gamblers, as well as free games and a special dynamite symbol. 30 winning ways may bring you money, and you can buy 6 free spins or a Bonus Respin Beat game. This Gamebeat slot machine has a 94.33% return-to-player percentage.

3. Gates of Olympus

Ancient Greece is a popular theme in the film industry, gaming, and literature, and gambling is no exception. That’s why Gates of Olympus by Pragmatic Play is one of the hottest casino games so far. Another reason for this 6x5 reel slot popularity is the quantity of special features it has. A scatter and a multiplier symbol, an ante bet, free spins, and a so-called Tumble feature help players win in this high-volatility slot machine. RTP both with and without active free spins is 96.5%.

4. Book of Ancients

Another game developed by the Gamebeat studio is devoted to the exploration and mysteries of Ancient Egypt, which is one more trendy theme. It has a standard 5x3 grid and 10 paylines. Three features diversify the gameplay, namely a scatter, a special expanding symbol, and free spins. The latter may be purchased. The return-to-player rate equals 94.06%.

4. Lost Mystery Chests

Last but not least title in our list of the best Loki feature-buy games is the Lost Mystery Chests slot game released by Betsoft. It has a classic 3x3 pattern and 10 fixed paylines. But the icing on the cake is the Mystery Chests bonus. These boxes may contain a regular or special (wild/scatter) symbol or even an instant cash win. When you play in the free spin game mode, you may be sure that you’ll get from 3 to 9 such boosters.

Your odds of hitting a jackpot in feature buy games are exactly the same as in regular slots. You have good chances to get some winning combinations, although the probability that they’ll drop depends on several parameters.

Volatility/variance

It’s the most important characteristic you should pay attention to when selecting a slot that pays out the most. In general, it shows the frequency and quantity of winnings. High volatility means gamblers hit significant jackpots, but it may happen a bit less often than they expect. On the contrary, low-variance slot fans win repeatedly, albeit their prizes are not so impressive.

RTP

It’s another parameter of slots that influences the payouts. The catch is that its impact isn’t seen in every single round but in thousands of spins made by thousands of gamblers within a long period.

So, what is RTP? This abbreviation stands for the Return To Player percentage and reflects the rate of total bets that returns to players in the form of winnings. The rest goes to the house as a token of appreciation for the fact they host the game. Once again, keep in mind that it is calculated for lots of gamblers, spins, and bets and cannot be noticed in a personal round.

Nevertheless, there are certain standards for this feature so that players get decent winnings. Usually, casino clients are not prone to gamble in slots whose RTP rates are less than 90%. Well, if we speak about regular slots, the requirements become even higher, but bonus buy slots already have in-built boosters for wins.

RNG

RNG, or the random number generator, is the key factor that influences the outcomes of spins on the whole and winnings in particular. And this is that very feature that you cannot change or choose. Gamblers can select slots with high or low volatility and check the RTP, but RNG is out of their control. For the sake of justice, we would like to note that it’s out of the control of online casinos as well. That’s why it’s a guarantee of fairness, both for the house and the player.

So, RNG is an algorithm that produces absolutely random combinations of numbers, and these combos are converted into the outcomes of rounds. That’s it. If you’re lucky you win, if you're unlucky, you don't. It's all by chance, and it’s the basis of slot machines and any other casino game online.

However, you can improve your winning odds when playing bonus buy games. How can you do that? Evidently, you can buy a bonus! It makes your chances to grab a big win skyrocket since bonus games are stacked with useful special features.

Loki casino plays fair. If Lady Luck is on your side, you can hit a bonus game without any purchase, just with the right RNG combination. Nevertheless, the random number generator is called so for a reason, and you never know what result it will create next time. In some cases, you may spin for long and don’t achieve any satisfying combo despite all bets and attempts.

Of course, there are situations when you get the outcome you want with no effort. If you feel it’s your day and you can achieve free spins in a couple of clicks, there may be no need to pay and spend extra money.

However, if you happen to have a losing streak, you risk wasting more money on bets than on the purchase, the more so because there’s a high chance to get some big winnings during a bonus game.

Gambling is about setting stakes, deciding on your strategy and manner of betting, and playing for real money. It’s a thrilling and challenging task, and lots of casino fans prefer to practice before real play.

The Loki casino online allows its clients to play feature buy slots for free. They can train, study the rules in action, and try out the bonus buy option. There are two main methods to do that: to play in demo mode and to use bonuses.

Playing for fun

If you mouse over a bonus buy slot machine in our slot catalog, you’ll see the Play For Fun button under the icon that launches the real money game. A simple click on it activates the demo version. You’ll get free credits to explore the title before betting your funds. As soon as you feel ready, you can switch to the real game easily.

Activating bonuses

This method is more beneficial since it combines the free game and the chance of winning real money. You can play with free spins (if there are any for a particular slot) or bet bonus cash.

How can you get them? This depends on the online casino you sign up with. Gambling platforms often provide a first deposit bonus, a welcome pack, a no-deposit bonus, or some other kind of bonus that allows you to enjoy real play without spending real money.

Combine it with purchasing free spins and you’ll get an unlimited number of bonus rounds!

Whatever you play – online roulette, blackjack, Texas hold ’em, or slots – you need to be sure that the game is safe for you, especially as long as you play for real money. Bonus buy slots include in-game purchases as well, so players need to know that their financial data is twice as well-protected. That’s why gamblers search for legal online casinos which hold reputable licenses.

The Loki casino online offers a safe gambling service, which is proven and guaranteed by the Curacao license. Our platform stores our clients’ data securely and uses it according to our privacy policy.

The Loki international casino offers many benefits to its new and loyal clients. Besides a nice slot collection that includes over 900 bonus buy games and a licensed service, players can enjoy more than 5,600 other official casino games.
