5 Slot Machine Bonus Features Worth Your Attention

Types of Bonus Features

Slot Machine Bonus Features

As the variety of features is vast and it can be difficult to decide which one is most entertaining, we’ve prepared a list of top 5 most notable features that will not leave you disappointed.

Free Spins

Free spins are currently one of the popular bonus features that most providers implement in their slots. Of course, players are waiting for it because it allows receiving payouts without risking real money! (We are talking about free spins as a slot bonus, not as a casino bonus).

Free spins are rounds in the slot when the casino bets and the client, in turn, receives the payout. Moreover, free spins often take place on more favorable terms for the player. They may have an increased RTP or additional bonuses, such as modifiers, multipliers, Wild symbols, and more.

Let's see how this feature works. Free spins can be started in many ways, the most common are: Scatters, accumulative system, prize, sudden start, purchase, and unique methods. How many free spins can a player get? Usually at least 5. If there are fewer, we are talking about respins (read below). The maximum number is always different, we even met a slot where a player can get up to 1,000 free spins!

Respins

Sometimes you lack just a little to make the right combination. Annoyance bursts you, and you want to add the missing symbol manually! Fortunately, lots of slots have a respin feature and it works as an “extra chance“. For example, you need three Scatters to trigger the bonus round but you only manage to get two. Then a superhero named “respin“ comes into play to help you! Respin can be free and paid, depending on the slot.

There is another kind of this feature called Hold & Win Bonus Round, which is used all over the place. The trick of the round is that now only cash/bonus/jackpot symbols land on the playing field. When they land, they become sticky and reset the number of respins (usually you get 3). This round can have three options for ending:

  • Respins are running out, all prizes are sent to your balance
  • By collecting 2-5 jackpot symbols you get one of the jackpots
  • The free space on the reels ends and you get a max win (Grand jackpot, for example)

Expanding Symbols

Don't underestimate the power of Expanding symbols! These special symbols can expand upon landing on a reel to cover all of its positions. Usually, the expanding symbols are Wild and this helps you a lot to create winning combinations. Such symbols can even get multipliers!

There are also slots with the extremely popular “Book of...“ mechanic. Many slot providers were inspired by the legendary Book Of Ra in its time. And even now companies continue to release “copies” of this slot. The main feature is the free spins feature, and one symbol will be selected before it starts. The selected random symbol will expand during the feature. And you can win no matter what position it lands in, as long as you hit at least two symbols per spin. You can re-trigger this feature and get one extra expanding random symbol each time, in some similar slots.

Modifiers

The next bonus feature worth your attention is “modifiers”. Modifiers are bonuses that can do various things in slots. For example, they can add Wild/Scatter symbols, award a multiplier, cash prizes, and even trigger a bonus game. This can lead to serious payouts!

In some slots, they can be triggered randomly in the base game/bonus round, and in some, you need to fill a special meter to activate them. For example, in the base game of The Magic Cauldron – Enchanted Brew by Pragmatic play you get five unique modifiers and two random Wild modifiers by filling up the star counter.

Bonus Wheel

The Bonus Wheel is the bonus feature, in most cases becoming the center of the slot machine. The fact is this wheel can award huge cash prizes and any bonuses described above!

For example, in Wishing Wheel by iSoftBet, the so-called “Wishing Wheel“ can trigger any of 6 features: Mystery Pipe, Rainbow Wilds, Mega Reels, Shamrock Sync, Rainbow Reels, or Ultra Reels. In Fruit Loot by Concept Gaming - with the Bonus Wheel. Here you can instantly win any of the trail bonuses with 3 levels of free spins features. As well as three levels of the Fruit Loot Bonus Round.

All in all, this is a pretty general bonus feature, but we hope you get the gist of it. Just by spinning the wheel, you can instantly activate a cool bonus!
