Here at Slots UK, we know all about the thrill of finding an online slot that keeps you on the edge of your seat and provides an unforgettable experience, complete with high-quality graphics, crisp animation, and an array of bonus features. Years ago, slot games were pretty basic and didn’t offer much in the way of frills, but these days you can find a smorgasbord of cutting-edge games which could rival their video-game counterparts for entertainment.
In particular, we know many players have a particular fondness for slots packed with bonuses, which not only provide an extra dimension of interest and excitement, but can also bring you some lucrative payouts. Long gone are the days of your staid and unremarkable fruit machine slots, with no special features to speak of - these days, bonus rounds are often the most stimulating aspect of many slots, and some even come with the power to make you a millionaire, such as the bonus round in Mega Moolah slot machine.
In this blog, we will explore these many alluring bonus features in greater detail, and provide some top tips on what these bonuses are, where you can find the best slot bonuses, and what their advantages are for players.
What are online slot bonus features?
As video slots have become more complex and sophisticated in nature, the kinds of bonuses they are able to offer have also become more diverse. In this section, we will shine a light on the different kinds of bonuses you may encounter, how you can trigger them, and what prizes they could bring you.
Free spins are one of the most commonly found bonus features, and offer just what the name suggests - spins which you don’t have to pay for. These free spins are normally activated by triggering three or more of the slot’s scatter symbol, and usually they come with a multiplier attached, which boosts any winnings you may happen to score. The number of free spins you may be given can vary quite widely, but often you will receive between 5 and 10 spins, depending on how many scatters you have landed.
Pick Me Bonuses
This type of bonus can be just as titillating as free spins, and can also often be triggered by landing three or more of the slot’s bonus symbol. When you do, you will be transported to another screen or set of reels, where you will find a number of objects to choose from - usually between 8 and 12 in number. These objects conceal various alluring prizes, which could include free spins, a sum of cash, or a multiplier. All you have to do is choose one, click on it, and reveal your prize.
Progressive multipliers are sometimes featured in slots in lieu of your more traditional bonus features, and come in the form of a meter, which you ascend with every win you manage to score. The higher you ascend, the higher the multiplier you will benefit from - some online slots also offer some kind of prize for you to aim for at the top of the meter, which could be a jackpot or some of those delightful free spins.
A number of slot game developers have begun to provide arcade games as their slot’s bonus feature, injecting some extra fun and novelty to your gameplay, as well as testing your skills. These games can include activities such as target shooting, requiring coordination and quick thinking, rather than just clicking on a box to see what’s inside.
This kind of bonus is also a little more complex and entertaining than free spins or Pick Me features, as it often comes in the form of a board game-style layout, which requires you to roll a dice or spin a wheel to move along. As you go, you could find yourself scooping some prizes along the way, such as multipliers or sums of cash. Reach the end successfully and you will net a jackpot!
In this type of bonus round, you get to enjoy a video-game style KO match, with your chosen warrior pitted against an opponent. The goal is to fight to the death - or, perhaps more enjoyably, to fight until someone manages to scoop the jackpot prize.
Which online slots have the best bonus features in 2021?
Now that you know a little more about what kind of bonus features you can find when playing online slots, it’s time to tackle the juicy question of which slots come with the finest bonuses of them all. It’s hard to choose just a few, as there are so many awesome slots out there with a whole variety of bonuses, each one appealing in its own way - but certain slots undeniably stand out from the crowd when it comes to the ingenuity or the potential winning power of their bonus rounds, and these can be found in the selection below.
This skilfully crafted slot game is not only thrilling to play thanks to the immersive graphics, animation and soundtrack, but also because of its gripping 5-tiered bonus round. It begins when you trigger three of the game’s amber scatter symbols, which automatically grants you 12 free spins. During this free spins round, one of five special dinosaur features will be activated at random, each one bringing a whole new level of excitement to your bonus round. For example, the Velociraptor feature will bring split wilds and multipliers, while the Brachiosaurus bonus comes with mystery multipliers, and the Triceratops feature introduces running wilds.
Game of Thrones
Developed by Microgaming, an industry veteran, the Game of Thrones slot is sure to appeal to players, not just because of the popularity of the books and TV series, but because of its truly thrilling bonus round. As with Jurassic Park, the bonus begins as a free spins round, triggered by three or more of the scatter symbol, represented by the Iron Throne. However, this free spins round comes with a special twist, because it requires you to select one of the four Houses - and whichever one you choose will determine how many spins you will receive, as well as other factors such as multipliers, and how many symbols with your chosen House banner you will gain. In addition, the Game of Thrones bonus section includes a Gamble Trail, which gives you the opportunity to risk everything by choosing to flip a coin, which could double your prize money - or take it all away.
This PlayTech slot is a firm favourite with many players as it comes with not just one but four bonus features, each more exciting than the last. These include the Colour Pink bonus, a quirky feature in which a wall of numbers is painted in pink and blue, with the pink numbers being combined and then multiplied by your total bet in order to bring you a cash payout, which you can choose to either keep or stake again. Then, there is the Crack the Pink Code bonus, which assumes a Pick Me format, requiring you to select from a number of safes, which open to unveil various free games with expanding wilds or multipliers. Perhaps most titillating of all is the special Jackpot Adventure feature, which asks you to open various doors and reveal different Pink Panther characters, in a bid to net a mysterious progressive jackpot.
If you define a great bonus round by how much money it can bring you, then Mega Moolah is sure to be the best bonus round of all in your estimation, as this slot has made many people millionaires, thanks to its progressive jackpot bonus. This special feature can be activated at random on any spin, adding a spice of excitement and nerves to your gameplay. When it does appear, you are given the opportunity to spin the jackpot wheel, and it is up to pure random odds as to whether you will land on the mini, the minor, the major or the whopping mega jackpot! However, if you thought this was the only bonus feature to be found in Mega Moolah, you would be wrong, as the slot also comes with a free spins bonus feature that offers 15 spins and a multiplier of 3x - so even if you don’t walk away with over £1 million, you can still add a nice amount of prize money to your bank account.
Hall of Gods
Another video slot which has gained a reputation for generating millionaires is NetEnt’s Hall of Gods, which has a thrilling bonus round which could potentially see you hitting a progressive jackpot. During this round, Thor’s notorious hammer comes in handy as a prop for smashing shields, behind which could be hiding a number of tempting prizes, such as mini jackpots and those coveted mega jackpots. If chances are on your side, the shield you smash with that mythical hammer could just end up being the shield that changes your fortunes forever!
Are bonus features an advantage for slot players?
At first glance, bonus features seem like a freely given gift from slot game developers - and, indeed, they have many more merits than downsides. They liven up your basic gameplay, they test out your skills, and they give you a slew of thrilling opportunities to win more prizes. In some slots, like Mega Moolah, they even have the power to change your bank balance.
However, there is one small downside to bonus features. Because developers have to factor the impact of these features into the slot’s RTP, the more special the bonuses are in a particular game, the more likely it is that you may have to wait quite a long time between wins during the slot’s baseplay mode.
That said, there are ways to avoid this, such as choosing lower volatility slots, where you know you will never have to linger too long before a payout appears.
Last few notes on slot bonuses and free spins
