Online Slots
Dive into the exciting world of online slots with this comprehensive guide. Learn the ins and outs of online slots, their strategies, rules, and variants. Understand the potential impact of bonuses and symbols and uncover reviews and rankings of the top online casinos boasting the best real money slots in the business.

Overview

Online bonus slots are remarkable casino games that enrich conventional gambling with a plethora of exciting features. These not only allow you to experience unmatched levels of gaming fun, but they also open the door to potential additional wins and win multipliers.

However, the excitement does not end there. Bonus slots also feature free spins, bonus rounds, wild symbols, scatter symbols, progressive jackpots, and more. Each of these features syncs up with a memorable theme and gives punters unforgettable gambling experiences. Check out our bonus slot features section to learn more about each individual feature, and join us on this quick dive into the world of online bonus slots.

Understanding Bonus Slot Types

Bonus slots can generally be broken down into two major categories. The first one are reel-based bonuses, and the second one are non-reel-based bonuses. Each of these brings unique and riveting features to the table, with the reel-based bonuses amounting to:

  • Free Spins - By far one of the most common reel-based bonuses that appear when you land a specific combination of symbols. You usually get a set of free spins that you can win real money with.
  • Multiplier Features - These can multiply your winnings by a set amount, such as 2x, 3x, and so on. They are a common part of base games, with a strong presence in bonus rounds.
  • Wild Symbols - They can substitute other symbols and thus form winning combinations, which essentially means that they increase your chances of winning.
  • Scatter Symbols - These special symbols can trigger bonus features, such as free spins or bonus rounds, regardless of where they are on the reels.
  • Cascading Reels - This bonus feature removes winning symbols from the reels and allows new ones to fall into their place. If new symbols result in wins, the cycle repeats itself.
  • Sticky Wilds - These symbols stick to the reels for a number of spins, which increases your chances of hitting winning combos.

If reel-based bonuses are not your cup of tea, you can always partake in non-reel-based ones, such as:

  • Pick-and-Click Bonuses - These are bonus games that have you select objects, symbols, or options. Each selection presents a prize, such as a cash reward or multiplier.
  • Wheel of Fortune - Certain bonuses are Wheel of Fortune-style games that have you spin the wheel and land a prize. The latter can be anything from cash to free spins.
  • Bonus Rounds - These are various mini-games that have you interact with cards, take on challenges, or simply partake in a quirky take on the base game that can lead to substantial payouts.
  • Memory or Matching Games - These bonuses have you match symbols, cards, or other items to reveal prizes.
  • Trails Bonuses - These have you move along a path or trail whilst collecting prizes or multipliers. Your final winnings depend greatly on your choices.
  • Jackpot Bonuses - You can compete for a progressive jackpot or fixed jackpot simply by landing specific combinations or symbols.

Worldwide Progressive Slots Bonuses

These incredible worldwide progressive slots are accessible to punters around the world, which means that their jackpot is increased by wagers from all over the place. They are based on network jackpots that are formed by interconnecting slot games hosted by different venues. Such linking, either local or area-wide, results in massive jackpots that can swell to multi-million-dollar sums.

Triggering worldwide progressive jackpots, which are in themselves a bonus slots feature, is relatively straightforward. You usually need to land a specific combination of symbols or jump into a bonus round, with the bonus round type depending entirely on the game at hand.

While landing the main progressive jackpot is incredibly rare and based greatly on luck, there are secondary progressive prizes. These can be won more frequently, thanks to their smaller symbol combinations, but they do amount to smaller payouts.


Choosing Your First Bonus Slot

Diving into the exciting world of bonus slot casinos is an unforgettable and pleasant experience. However, you need to know exactly what you are getting yourself into. You have to figure out which bonus feature appeals to you the most, such as free spins, interactive bonus rounds, or something else. Once you have that figured out, you have to set a budget that you can afford to lose. Then, you have to find game themes and game features that align with your preferences, which will be pretty easy, thanks to the vast game libraries of bonus slot developers and their operators.

Just because a bonus slot looks amazing does not mean that it is. You should have a closer look at the return to player (RTP) percentage. Then, you should have a gander at volatility, with low volatility slots paying out smaller but more frequent amounts and high volatility slots offering larger but less frequent payouts. If you want an even deeper understanding of the slot, you simply check out customer reviews, along with the demo and free play options.

If all of the above boxes are sufficiently ticked, you can then start to consider mobile gaming on your preferred mobile device and potential bonuses or promotions. However, we understand that this entire process takes a lot of time and effort, which is why we have prepared an extensive list of recommended first-class online bonus slot casinos for you to enjoy.


Bonus Slots Winning Combinations

Different bonus slots winning combinations rake in different prizes, ranging from cash and standard bonuses to progressive jackpots. The prize that you land depends on the paytable at hand, with each bonus slot game having different prizes at different prize levels. These prize levels can be greatly impacted by various unique symbols, such as wilds and scatters.

Winning combinations can be formed on active paylines or completely at random, with the last option requiring the slot to have a win-anywhere mechanic. Symbols are usually matched from left to right, with the most common representation being fruits, numbers, letters, and themed characters. A wild symbol can take the place of other symbols, while the scatter symbol can trigger bonus features such as free spins or bonus rounds.

Wins can be further increased by multipliers that enhance winning combinations and add value to your win. Winning combinations get even more exciting in bonus rounds that are essentially mini-games, such as pick-and-click or other interactive games.

The kings of winning combinations are those that land players progressive jackpots. These can be specific winning combinations that appear in bonus rounds or completely random occurrences that pop up during basic gameplay. We advise that you check out your chosen bonus slot’s rules and see what kind of winning combinations and win conditions you are dealing with.

Tips

Bonus slot casinos are incredible institutions that offer a lot of fun gaming and unforgettable scenarios. However, not all bonus slot features are made equal. Maximize your bonus slot gaming with the following handy tips:

Getting Started

Everyone wants to partake in bonus slots and reap the rewards of bonus features. However, few people know how to get started properly. We invite you to check out the following breakdown of key aspects so that you can easily join a bonus slots casino today.

1 Pick Reputable Casinos

It is crucial that you choose a reputable and licensed online casino that boasts good reviews, a valid gaming license, top-notch encryption, a vast game library, responsive customer support, and more. You can find a selection of these elite bonus slots casinos on this very site.

2 Practice with Free Slots

Free slots are the perfect way to see what triggers bonus features in real-time. Playing these remarkable titles does not require any monetary risk, and you can easily access them on various online gambling sites.

3 Play for Fun

Remember to only ever play online bonus slot games for fun. Focusing on landing jackpots or accumulating wins will cause unnecessary stress and fatigue. If you start becoming anxious, immediately take a break.

Bonus Slot Features

Bonus slots have exciting features that elevate the gameplay while also providing unmatched winning potential. Each bonus feature is unique and brings a fresh layer of excitement to your online gambling adventures. Check out the following breakdown of the most popular features to learn more:

Free Spins

Your typical online slot bonus feature that allows you to spin reels without spending a dime. Each spin potentially holds a winning combination, with specific sets of symbols raking in more free spins.

Bonus Buy

It is an incredibly popular and handy mechanic that allows you to directly purchase access to bonus rounds or free spins features. While there is an additional fee to skip conventional gameplay and jump straight into the bonus round, it does offer significant payouts. Certain bonus rounds even allow punters to win additional free spins by landing certain symbols, which significantly prolongs gameplay. However, some jurisdictions, such as the UK, ban bonus buy features.

Bonus Rounds

These are essentially mini-games within your slot game. They boast unique gameplay and have the potential to rake in substantial prizes. You can usually trigger them by landing specific symbols or combinations.

Wild Symbols

These unique symbols can substitute other slot symbols, thus completing winning combinations. The appearance of your wild symbol usually matches your slot’s theme, so make sure to know what it looks like before starting your gambling session.

Scatter Symbols

Another exciting slot symbol that triggers various bonus features. The main benefit is that they pay regardless of their reel position, with some even pulling in neighboring symbols.

Progressive Jackpots

Some bonus slots attract punters by offering life-changing wins. These grow with each placed wager until one lucky player eventually manages to land them. You can land them in bonus rounds or completely at random.

Multipliers

It is one of the most exciting ways to compound your wins, especially if you manage to stack several multipliers in one spin. You can expect to land multipliers during the base game or whilst partaking in bonus rounds.
