Bonus Functions In Online Slots

online slot game

While online slots come in different colors and shapes, they all have one thing in common. They enable players to hit sweet winning symbol combinations and rake in sizable jackpots, making slots one of the most played games across online real money casinos. Unlike classic fruit machines with super simple gameplay, modern slots burst with exciting feature functions to offer spinners an increased level of enthusiasm and entertainment. They also pack all of those bells and whistles that make them look and sound like Hollywood blockbusters rather than online casino games. 


This article sheds light on bonus functions in online slots. So read on to know more!


Two types of slots


So what bonus features can you expect to see in slot machines? Well, it depends on the type of game that you play. A classic 3 reel slot, for instance, keeps things pretty simple. It usually features only 5 paylines and offers payouts in exchange for 3 matching symbols represented by fruit images, as well as bell, 7, bar, star, and horseshoe icons.


A contemporary video slot is an entirely different beast with completely different looks, plus the winning potential modern games pack is next level. Impressive winning opportunities are available via a bigger number of reels (5 at least) and paylines (from 10 to 50), or even via hundreds of win ways. With various exciting bonus features and snazzy graphics, modern free slots have everything necessary to keep your champion dreams alive. Of course, the enthusiasm flies way higher with some real money or Bitcoin wagers involved. Below, we list bonus features found in modern slots and responsible for amplifying your payouts.




The majority of slot machines, both classic and modern, will treat you to a wild feature, a favourite amongst many spinners, especially if it comes with various boosters, more on this below. So, a regular wild symbol is used as a substitute for any other image in a game except a bonus/scatter icon. For instance, if you have 3 identical icons and a wild on a payline, you will end up being paid for 4 matching symbols. 


Sticky / multiplier / expanding wilds


Modern video slots take a wild feature to a new level. They make it possible for wild symbols to expand across reels, be held in place for the following spins, or even give them a multiplier twist. If you take a look at the Deadwood slot, one of the most celebrated Bitcoin games available across all of the best online casinos, you will find that a wild image here has a growing multiplier attached to it. To be clear, every time a 4 row tall wild nudges, it increases a multiplier by 1x, the feature that flowers in full splendor in the free spins where a multiplier value has no limit. There are many other wonderful crypto games that benefit from sticky wilds paired with multipliers, including the iconic Diamond Vortex Bitcoin slot by Play ‘N Go. Play this one and try not to miss the 5,000x your wager top payout, which is all the sweeter if pocketed via WildTornado’s delicious Bitcoin bonus.




Scatters are special symbols used both in old-school and brand-new slots. They are special because apart from paying from any position on the reels (unlike regular images that are strictly associated with paylines), they are your ticket to massive payouts. This is because they unlock free spin bonus rounds.


Free spins


Free spins are mostly exclusive to modern video slots. Just like generous online casino bonuses entice players into online casinos, in-game free spins suck players into the slot action with promises of mega payouts and thrilling entertainment. How do they come into action? Usually, these are between 3 and 5 scatters that trigger free games. As soon as those have appeared, you receive a certain number of bonus rounds. Sometimes, you can win more free games.


Free spins are so popular not only because you don’t need to pay for them. The main reason why free rounds are so exciting is that they unlock other special bonuses, the ones that pave your way to increased wins and hotter action. Take Book of Dead, another smashing crypto slot, as an example. The free spins game here activates an expanding symbols extravaganza, making it more likely for punters to take home sweet coin prizes. Digital wallet holders can try their luck with this great Bitcoin game at the WildTornado casino. Book of Dead is also available for fiat money betting action, should traditional players be interested.


A risk/gamble game


This is another terrific feature available in modern slots. Activated whenever a winning combination has been created, a risk game prompts you to guess the suit or the color of the card. If you manage to guess it, your winning is doubled or even quadrupled. Usually, you can repeat the process a few times, which gives you the chance to increase your initial payout by multiple times.


A bonus game


A bonus game is also a popular extra in online casino games and provides spinners with an extra chance to hit valuable combinations. It can come in various forms. One of the most common bonus games is a pick-and-click round, where you are presented with several symbols. You have to pick one of those or maybe a few. If you are lucky, your chosen image will then reveal a sweet coin prize.


As you can see, bonus functions in online casino games are multiple and delicious! So, why don’t you try those in the most trending free slots (no download) available at WildTornado, your best online casino! Go ahead, play games and have fun, and don’t forget to grab juicy Bitcoin bonuses also!
