Top Bonus Features

Howdy, mate? If you are done with your chores today, or if you have nothing to do at all, why not give me some of your time, eh? I will let you in some of my secrets in the world of top online slots, so you get more bang out of your buck!

Yesss! Not all top online slots are created equal, and I will show you the best ones that have the most generous bonuses! So sit tight and enjoy the ride!

Slot machines offered a minimal number of functions in the past. You had 3 spinning reels with about 10 symbols each, and when a certain combination of symbols lined up, you won money or candy. (That’s right – candy. When slot machines were temporarily banned, they used candy for prizes instead of money, so we have fruit symbols and strip symbols. Fruits represented the taste of candy, and the stripes represented chewing gum sticks.)

Nowadays slots offer all sorts of add-ons, including bonus games of varying difficulty, free spins features, the ability to “play” the prize you just won, and staggeringly large progressive jackpots. Symbols are no longer just symbols anymore. You now have bonus symbols, multiplier symbols, scatter symbols, and wild symbols. This page explores and explains some of the different features of top online slots.

Most modern online slot machines come with bonus features.

What Are Bonus Features?

The slots bonus is an optional feature that can be used to make money alongside your regular spins. It can be as simple as free spins, wilds, or it can contain complex multipliers that will improve your payout. As with all casino games, slots have a player return percentage (RTP).

Bonuses can be triggered in the slot at any time. Some games have random cash wins that are shown as you play. However, most bonuses are activated when certain symbols are lined up on the reels. These can be wild symbols or scatter bonus symbols that pay out no matter where they appear on the reels.

You get not only a small prize by hitting scatters, but when you have three or more scatter symbols you activate one of the game’s bonus features.

The fun starts when the player launches a special bonus feature in which he has an opportunity to play 4 types of free spins (Loki, Valkyrie, Odin or Thor). The player can get additional wild symbols plus various multipliers. When players are presented with a random wild reel for extra prizes, they should try to get the Thor symbol on the middle reel. Then the Wild Storm will be triggered.

Extra Chilli

Extra Chilli is a classic slot with cascading reels! This is a slot that will drive you crazy! It’s a simple slot, but exciting with insane payout potential. It wouldn’t be fair if this game wasn’t on our list of the best slot machines.

The bonus is only worth 50 times your stake and is one of the cheapest you can buy. It gives you 8 free spins right off the bat. If you have the guts, you can bet 50/50 to increase the number of spins to 16. However, if you miss, you will have to leave empty-handed.

You can continue the game up to four times, which could potentially give a total of 24 spins. After you have completed the first game of chance, your chance of getting more spins increases from 50% to 60%. You are also guaranteed some free spins, even if you miss.

Each win in the free spins rounds gives you +1 multiplier. This means that the more spins you have, the more likely you are to get a higher multiplier, and the higher the multiplier, the higher the payout potential.

The Rift

The Rift is a famous game released by the developer Thunderkick. If the player wants to try a new and interesting slot machine with bonus features, Rift is the right choice.

If the 2 scatter symbols land on the reels, players are given the opportunity to re-spin with the possibility to get 3 wild symbols on the reels.

To activate the free spins bonus, there should be 3 or more scatter symbols that can land anywhere. The maximum number of extra rounds that can be won is 20. There is also the option to activate many levels of fun during the free spins.

Game of Thrones

Game of Thrones is a well-known themed slot created by Microgaming. The highest prize can be won when the player receives the Game of Thrones symbols.

The bonus feature can be activated by landing 3 scatter symbols. The best part is that the player can choose any bonus he / she wants. There are 4 possible options with different free spins values ​​and multipliers to choose from. So do your moves wisely.

Many of today’s slots feature at least one bonus round. Popular slot games, meanwhile, may feature two bonus rounds or even three. Always check the paytable of the game before you start playing so you know what bonus symbols to look out for.

Gamble Feature

Some slot games offer the option to gamble every win. Gambling is especially popular in classic slot machines, which are often referred to as “fruit machines”. The most common (and simplest) version of this feature is the ability to predict the suit of a playing card that will be displayed on the video screen. If you guess right, you can double the amount you just won. However, if you are wrong, you will lose what you just won.

Top Online Slots Bonus Games

My favorite feature of modern slot machines is the bonus game. These are special games (often video games) that are “unlocked” as you play using the different combinations you hit on the reels. An example of a bonus game is “Wheel of Fortune” widely used slot machines of the same name. This bonus game is so popular that I read anecdotes about players who won the progressive jackpot and were disappointed that they couldn’t spin the wheel.

Some bonus features contain an element of skill, while others are completely random. Of course, launching the bonus game is a matter of luck and there is no skill element here.

Random Win/Click Me Feature

Some slot games will reward a random prize during the base game. This can happen at any time and may include a small cash prize or a single re-spin round. Click Me/Instant Win bonuses are usually triggered if you land three scatter symbols anywhere on the reels or three from left-to-right. Then the icons will turn into mystery symbols and you’ll have to select one of them to reveal a prize.

Example: Royal Reels slot (Betsoft)

Free Spins

Some of the best slots bonus features include free spins where you can play additional rounds for free.

You can play free online slots at the best online casino sites to get a feel for the volatility of the game. This is the overall frequency with which the online slot launches its bonuses. If you try a lot of games it will help you determine the best slots for the bonus feature.

Free spins bonus is the most popular online slots bonus feature. Free spins bonus come in many flavours, but the most common is triggered by hitting three or more scatters.

Often free spins bonus will have a multiplier attached. Thus, everything you win due to the bonus feature will be multiplied.

Example: Game of Thrones slot machine (Microgaming)

Free Spins Retrigger

Basically, restarting means restarting the bonus game. This is a popular feature among slot game players as it often results in very large wins. The free spins round is often re-triggered when the same three symbols that triggered the game reappear on the reels during the free spins round. Restarting can happen multiple times in a row, which can lead to successive bonus rounds, even if we haven’t found a slot that repeats forever!

Cascading Reels

Cascading reels is an innovative slot machine feature that has gained popularity in online gem games. As soon as the symbols hit the reels, all paylines explode, and new symbols may appear in their place. When substitution symbols create new winning combinations, they also explode, and more symbols appear in their place. It doesn’t last forever, but it’s a great add-on that adds a bit of action to the main game.

Example of the game with Cascading reels feature: Extra Chilli (Big Time Gaming)

Pick Me Bonus

The Pick Me (Pick’Em) bonus can be also triggered if you succeed in landing three and more relevant bonus symbols. Normally, the player is taken to a second screen of the game where they will have 8-12 objects to choose from. Each object hides a cash prize, a multiplier bonus, or sometimes free spins round.

Players are offered a set number of picks or they keep on picking until they land the ‘Collect’ symbol. When it happens, the players come back to the reels and continue to play as normal.

Example of the game with Pick Me Bonus feature: The Slotfather (Betsoft)

Wild/Scatter Combos

Some of top online slots offer simple cash bonuses if you hit winning combinations of symbols on the reels. It might be scatter symbols on the middle reels only, or a scatter and a wild symbol together.

Placeholders in slot machines work in the same way as placeholders in card games. They replace the symbol you need to receive your payout. Wildcards are also popular with players, but not as popular as scatter and bonus symbols.

Example of the slot game: Werewolf Wild (Aristocrat)

Expanding Wilds

The wilds expansion hits one position on the reel but then expands to cover all the other symbols on that particular reel. This can create several new winning combinations, especially in a five-reel, multiple payline slot. Expanding Wild is a popular twist in a traditional feature that can lead to very big wins.

Shifting Wilds

The difference between shifting wilds and their sticky counterparts is that they move around the reels with each spin. Each time new symbols appear, the wild is combined with them to form paylines, and this continues for a period of time until the wild is completely displaced from the reels.

Stacked Wilds

Like expanding wilds, they can bring big wins. They are usually found in stacks of 2, 3, 4, or 5 wild symbols that cover part or all of the reel. Different games use different ways to use stacked wilds.

Sticky Wilds

The term sticky wild may not sound like the most attractive in the world, but trust me, it is one of the most lucrative wilds featured in modern games. Whether it’s a round of the main game or a bonus feature, Sticky wilds will stay in place for further spins, which can create some really exciting winning combinations.

Transferring Wilds

Transferring wilds, sometimes referred to as nudge, is an increasingly popular feature found on many modern slot machines. Specifically, one of the slot machine companies that has released a number of casino games with transfering wilds is WMS.

Random Wild Symbols

Wilds are almost always present in modern slots and provide an opportunity to turn missed opportunities into big wins. For the most part, the random wild symbol works just like any other. When transforming characters, the difference is how they appear, which, as the name suggests, is completely random depending on the theme and structure of the game.

Walking Wilds

This feature gives players the option to receive free spins when they receive a substitute symbol on the reels. Depending on the game the players are playing, jokers move left, right, or both directions.

Trail Bonus

A Trail Bonus is usually triggered if you hit three or more bonus symbols – scatters, this bonus game feature plays a little like a table game. On a second screen you’ll spin a wheel or probably roll a dice to move a character along a prize trail. While spinning the wheel you may win different prizes: cash, free spins bonus or multipliers. You can even hit the jackpot.

Example of the game having the Trail Bonus: Rainbow Riches (Barcrest)

Combat Rounds

Some modern slots offer fight rounds where your chosen ‘fighter’ participates in a scrap to the death to get the jackpot. Such a feature doesn’t involve much skill, as you just need to select fighters and watch the carnage.

Example: Beowulf (Quickspin)

Multiplier Symbols

Multipliers are symbols that multiply your winnings by a certain amount. For example, if you have a 2x multiplier symbol and it is part of a winning combination, you will receive twice as much money as without this multiplier symbol. Games with multiplier symbols are very popular among slot machine players.

Instead of bonus game rounds, some slots are incorporated with progressive multipliers, which usually run 1x, 2x, 3x and so on.

Progressive Jackpots

The progressive jackpot gradually increases as players place their bets on slot machines. A tiny percentage of each bet brings the highest jackpot. These games offer higher odds of winning than the fixed jackpot (or “flat top”), but the jackpots are huge. Megajackpots is one of the most popular progressive jackpot games. It starts at $ 10 million and continues to grow.

Some of these progressive jackpots are networked across multiple machines in one casino, while others are networked across multiple casinos.

Example: Arabian Nights (NetEnt)

Why Are the Bonus Features Good for Slot Players?

Bonus rounds make slots more interesting and attractive for players, they also allow developers to offer players something new and exciting.

While they can cash out a lot of money, the developers have to play against payout bonuses in the base game. The regular payouts can often be small for slots with decent bonus features. This makes the slots with sophisticated bonus features a little more volatile in comparison to the classic games with fewer bonuses and with smaller but more regular winnings.


How to Trigger a Slots Bonus?

Now, there are a lot of randomly triggered modifiers that can enhance your gameplay. For example, you can trigger slot bonus features by landing scatters, wild symbols, bonus multipliers, or probably random re-spins for earning some extra cash.

What Things Should I Pay Attention to While Choosing a Slot Machine?

First, you should pay attention to RTP - Return to Player percentage, which is the average, long-term return made to players over millions of spins. Then you should check whether the slot machine has some bonus features like free spins or/and multipliers. Pay also attention to volatility (higher volatility - better winning chances) and check out the paytable of the game.

Here are some of such slots: Who Wants To Be A Millionaire (Big Time Gaming), The Game of Throne (Microgaming), Wheel of Fortune: On Tour (IGT), Immortal Romance (Microgaming), Vikings Go Berzerk (Yggdrasil Gaming) and many others. The complete list you’ll find on our site.
