Before we go into the bonus features, you should take a look at the best slots with bonus rounds available in online casinos
today, and then come back to read about the most frequently offered bonus features and how they work.
While there are countless of bonus features available in slots these days, they are all based on the standard ones and represent better versions of them. Take a look at the most commonly offered ones:
The Wild is the symbol that you use as a Joker in playing cards. It is the symbol that will help you form winning combos when you lack one symbol to complete the combo. For instance, you land 2 Cherries on an active payline, and one Wild. The Wild will substitute for the missing third Cherry symbol, and you’ll get your winning combo.
The Wild has several improved versions in the newest slots. It can appear in the form of a Stacked, Sticky, Expanding, Shifting Wild, etc. Even though these forms give you additional benefits, as covering an entire reel and helping you form winning combos on several paylines, or sticking on the reels for extra spins, they still have one purpose: to replace for symbols when you lack one.
Scatters and Free Spins
Scatters, in addition to plenty of other roles, mainly assume the role of a trigger for an additional bonus feature. Mostly, they are responsible for triggering the Free Spins or in some slots called Free Games. In most 5 reel slots, you will need to land at least 3 and up to 5 Scatters to trigger 10 or 20 Free Spins.
Free Spins, on the other hand, are your tickets to free play. Once triggered, you have 20 Free Spins to play, for which the same stake applies, even though you’re not paying for it. It means that, if bets range from $0.10 to $100 and on the triggering spin you’ve placed the max bet, each of the 20 Free Spins will be played with that bet, you won’t be the one who pays but you will be the one who gets those insane payouts.
Gamification is the latest trend in online slots, so most developers, NetEnt in particular, have started creating slots that look and feel more like video games because they have begun offering online slots with bonus rounds on several levels or stages.
Therefore, as you trigger the bonus game, you will need to create winning combos, or fill different types of meters with symbols to level up and progress to the next levels.
Of course, there’s a target: a life-changing sum waiting for you at the last level. These mini-games have various names, depending on the theme of the slot. NetEnt
’s Wild Worlds
is a perfect example of such a slot. You go through worlds or levels, and you fight villains to get to a $1 million payout! See why you need these bonus rounds?
One of the best slot bonus rounds you can ever get is cascades. This is a feature that, once you see it, you would like for it to be present in all casino slots with bonus rounds. What happens here is: you land a winning combo, and the symbols that form it are removed from the reels, while new one's cascade or fall from the top of the reels, providing you with brand new chances of triggering more wins and improving your payouts. A yummy slot to try which offers cascades is Play’n GO
’s Sweet Alchemy
Multipliers are also highly valuable. They can appear attached to Wilds or Scatters, or there can be a Multiplier meter next to the reels which get filled as you from winning combos. Its name is self-explanatory, but still, this is the feature that multiplies your wins under certain conditions.
