Seasoned slot players know that hitting a bonus round can dramatically change the course of your play session, often leading to the most thrilling and profitable moments in online gaming. Bonus rounds add depth and excitement to the slot experience, providing opportunities for big wins through innovative and interactive features beyond the standard reel spins.

Online casinos have eagerly embraced these enhanced games, often featuring dedicated sections for slots known for their rich bonus rounds. Not every slot offers these sought-after features, so we've curated a list of the best online slots renowned for their rewarding and entertaining bonus rounds. This guide aims to simplify your search and ensure you have direct access to slots that promise a fun gaming experience and the potential for substantial payouts through their unique bonus features.

What are slots with bonus rounds?

Modern slots are completely different from the ones you might have seen in the early 2000s. Nowadays, such games come with bonus rounds. These projects are designed for users who know what they want from slots. In short, with bonus rounds, a participant can win much more than he/she ever had. However, this can be done with a higher risk. It is the price that users should pay to get better results with bonus rounds.

To understand how games with bonus rounds work, the participant should publish at least a few titles and play a little. If he/she gets winning combinations at the right time, he/she starts a special mini-game with the ability to get some good wins with bonus rounds. It can be not only dollars but also other types of bonuses.

But how can the user find such projects with bonus rounds? Because of the internet, it’s easy. The contestant should open any web browser and type in “free slots with bonus rounds”. As a result, he/she will get some links to online casinos with a list of titles. Then, it is up to the user to decide what game they want to enjoy.

The truth about bonus round projects is that they are easy to understand, even for beginners. All players get tips and rules on maximizing their profits from all projects. It’s a common feature of almost every game on the internet. As with all other products from the major studios, slots with no download no deposit bonus rounds are also available.

This is pretty awesome for users who have never played such projects. They get the chance to open a few slots with bonus rounds and quickly find out how they can work to make money with these digital products.

How to play slots with bonus rounds?

  1. Choose an online slot with a bonus round
    Don’t play slots from dubious providers if you want to save money and have a good chance of winning. Play exclusively at licensed online casinos that work with reputable game providers.
  2. Use bonuses
    Online casinos often have a small number of slots that offer bonuses. Players can get bonus spins, free spins, or cash rewards. The user must familiarize himself with the conditions for obtaining bonuses. Later, the player can manage the bonuses properly and withdraw the money without much effort.
  3. Play slots with high RTP
    Play slots with high RTP. The higher the RTP, the better your chances of winning.
  4. Choose slots with small jackpots
    Choose slots with small jackpots. The smaller the jackpot, the easier it is to win.
  5. Play as many paylines as possible
    Nowadays, there are many slots with more than 100 paylines. The more paylines there are, the greater the chances of getting a winning combination. In the game, try to bet on the maximum number of paylines.
  6. Control your finances
    When playing slots, remember to control your bankroll. Clearly define the amount you are prepared to lose and do not go beyond that. Also, it would help if you never played credit games.

Differences between slots with free and paid bonus rounds

In the games on the market, we can find two types of bonus rounds: paid and free. Free bonus rounds do not require the player to invest any funds. They can be triggered by hitting a certain combination on the paylines. The detailed conditions are always clearly defined by the developer behind the game’s production. However, there is one very important detail. Slots with free bonus rounds offer lower chances of winning; this is logical as no casino would like to lose too often without getting anything in return.

The situation is slightly different for paid bonus rounds. The player must not hit a certain combination to trigger the bonus round. Usually, it is enough to pay a certain percentage of the total stake, and the bonus round can always be activated. In this case, the chances of winning a prize are much higher as the casino makes money from it and can take more risks.

Types of bonus rounds in online slots

It isn’t easy to define specific types of bonus rounds. Competition in the online slot market is fierce. Each provider tries to make the bonus options in his games original and unique. However, due to certain patterns, several basic bonus rounds can be distinguished.

Pros and cons of slots with bonus rounds

Like everything in the casino, the bonus round has pros and cons. To be objective, we’ve outlined the biggest advantages and disadvantages of bonus round slots below.

Strengths
  • Bonus rounds often come with additional features like multipliers, free spins, and special wilds, significantly enhancing your chances of hitting a big win.
  • Bonus rounds add a layer of excitement and variety to the gameplay, making the experience more engaging. Often, they include unique themes and interactive elements that are not found in the slot’s regular play.
  • Slots with bonus rounds typically offer a higher RTP during these segments. This means the payout percentage increases when a bonus round is activated, potentially leading to better wager returns.
  • Many bonus rounds do not require additional bets. Once triggered, they allow you to increase your winnings without risking more of your own money, which is particularly appealing for players on a budget.
Weaknesses
  • Some slots offer the option to buy into a bonus round. While this can be tempting, it can also lead to spending more than planned without a guaranteed return on the investment, making it a risky move financially.
  • For some players, especially those who prefer a straightforward gaming experience, the additional features and complexity of bonus rounds can be overwhelming and detract from the game’s enjoyment.
  • To compensate for the high payouts often seen in bonus rounds, the base game in some slots may offer lower payouts, making regular play less rewarding.
  • Not all bonus rounds are created equal. Some may seem lucrative but offer minimal real benefits, or they may trigger so infrequently that the average player rarely gets to experience them.
  • Slots with elaborate bonus rounds might skimp on other potentially rewarding features or gameplay dynamics. This can mean fewer wilds, scatters, or standard reel payouts, as the focus shifts to triggering the bonus.

Popular online slots with bonus rounds

Below, you will find some online slot machine games that have bonus rounds.

Book of Dead by Play’n GO

For a long time, the Novomatic Slot Book of Ra was the absolute favorite of many players in land-based and online casinos. However, when Novomatic withdrew from the online business for a while, other software developers created games with similar features that made Book of Ra popular.

Book of Dead from Play’n GO is quite similar to the Novomatic original in design and bonus games. However, it should be noted that the game can hardly be compared with the classic Novomatic slots in terms of visual and acoustic aspects.

Book of Dead is a slot in the classic 5×3 format with everything players could wish for. The most important symbol in this game is the legendary book, representing both the wild and the scatter symbol. As a wild, it substitutes for all other symbols, increasing the likelihood of a winning combination. If it appears three times on the reels, it activates ten lucrative free spins as a scatter symbol. Another wild is randomly selected before the bonus round starts, giving you even better chances of winning.

Immortal Romance by Microgaming

Although the Microgaming slot Immortal Romance was released in 2011, it is still one of the most popular slots with bonus rounds in online casinos. The game was developed when there was real hype around vampire stories like “Bit at Dawn” or “Interview with a Vampire”. Even today, he has many fans due to the exciting story and his bonus games.

Like most slots with bonus rounds, Immortal Romance offers lucrative free spins. However, these differ from others because the more free spins bonus rounds are activated, the more free spins are unlocked and the higher the multiplier becomes. There are also other features, such as rolling reels and the wild vine feature.

Gonzo’s Quest by NetEnt

When the Swedish software developer NetEnt released the slot Gonzo’s Quest in 2010, the community was enthusiastic because the game introduced completely new features. Although several years have passed, and numerous new slots have populated online casinos since then, Gonzo’s Quest is still the absolute favorite for many fans.

Gonzo’s Quest owes its popularity not only to its stunning graphics and lucrative bonus games but also to the animated Spaniard Gonzo, who dances for joy or otherwise reacts to the gameplay. Gonzo’s Quest is presented in the 5×3 format, but instead of the spinning reels, blocks fall down (Free Falls) and form a winning combination.

If a win is made, the blocks involved will shatter and be replaced by new ones. This gives you the chance to win again within a game round. Each time the multiplier increases. Gonzo’s Quest also has a wild symbol that substitutes for the other symbols and also a scatter that awards ten free spins if it appears three times.

Starburst by NetEnt

NetEnt’s Starburst is a real classic in online casinos. Released in 2012, it has lost nothing of its fascination and has numerous enthusiastic fans. As far as graphics, sound effects and bonus games are concerned, Starburst is probably unique in online casinos. The game also keeps the player spellbound with its action-packed gameplay.

Starburst has no free spins, but the game can easily do without free spins because the slot has several other exciting features in its luggage. Winning combinations on the slot in the 5×3 format are formed from left to right and from right to left. The bonus feature is activated when a colorful sun appears on the reels. It then spreads across the reel and creates a re-spin. At the same time, the sun symbols act as wilds, which complete every winning combination.

The Dog House by Pragmatic Play

When Pragmatic Play released its game The Dog House in 2019, not only dog ​​lovers were enthusiastic. The game enchants with its lovingly designed dogs and features many exciting functions that ensure considerable payouts, both in the base game and in the bonus rounds.

The dog house represents the wild symbol and appears on reels 1, 3 and 4. There it substitutes for all other symbols except for the scatter and provides regular payouts. The dog paw is the scatter symbol. It appears on reels 1,3 and 5.

If all three are shown, the bonus game round is activated. Before that, a slot appears in 3×3 format with several free spins on each symbol. These numbers are added together to give the total number of free spins. Also, in the bonus round, all wild symbols remain in place when they appear.

Vikings Go To Hell by Yggdrasil

Vikings Go To Hell by Yggdrasil appeared in online casinos in 2018 and is a worthy successor to its popular predecessors, Vikings Go Berzerk and Vikings Go Wild. In this part, the brave Vikings even go to hell and fight Lucifer himself. The game is inspired by its idiosyncratic structure, graphics, rousing sounds, and, last but not least, exciting bonus games.

The game appears in 5×4 format with 25 pay lines. Four Vikings are shown on the left margin, showing their “Berzerk Level,” which increases with the corresponding winning combinations. There are also three different bonus games. The demon acts as a scatter. Seven free spins are awarded if it appears three times on the reels. Twelve free Spins are awarded for four Scatter symbols and appear for every five. There are 16 free spins available in two modes.

The first time the player enjoys the Lord of Chains Free Spins with Sticky Wilds. During the next free spins bonus round, the Lucifer mode is activated, in which all wins are tripled. Landing two symbols of the demon-fighting a Viking activates the Rage & Wilds feature and two respin symbols award another free round of sticky wilds.

Avalon by Microgaming

Microgaming’s Avalon slot is one of the most popular from this developer. Despite being present in online casinos since 2006, the game is still among the favorites of many players. Avalon takes the player back to the world of King Arthur and the Knights of the Round Table in the Middle Ages. The game has simple, detailed graphics and lucrative bonus games.

Avalon appears in classic style in 5×3 format and 20 paylines. Three different bonus symbols provide additional payouts. The Avalon symbol and substitutes for all other symbols on the reels represent the wild. The lady of the lake appears as a scatter. If she appears three times on the reels, there are twelve winning free spins. The treasure chest also gets a new role in the bonus round because it then acts as an additional wild symbol that ensures even more wins.

Thunderstruck II by Microgaming

With Thunderstruck II, released in 2010, Microgaming wanted to build on the great success of Thunderstruck from 2004. This slot is not only one of the favorite games for players fascinated by Norse mythology, but this game can certainly compete with many new slots.

Thunderstruck II was one of the first Microgaming games to feature the 243-ways-to-win format. This means there are no paylines, only possible winning combinations. The chance of hitting a win is far higher on games in this format than on the classics. The bonus free spins rounds are particularly interesting.

To activate this, the scatter symbol, the hammer of the god of thunder, Thor, must appear three times. Each time free spins are activated, you level up. This means ten free spins are in the first free spins bonus round and 15 in the next. Players can secure up to 25 free spins if they try their luck with Thunderstruck II for longer.

Dolphin’s Pearl Deluxe by Novomatic

One of the most beautiful slots from Novomatic is the Dolphin’s Pearl Deluxe slot, which takes the player into the mysterious underwater world, where he meets the sea inhabitants. Despite its simple structure, this game is still very popular among players today, both in terrestrial arcades and online.

The two most important symbols are the dolphin and the shell with the pearl. The dolphin acts as a wild, substituting for all other symbols, while the shell activates 15 profitable free spins if it appears at least 3 times. Winnings are also tripled during the free spins bonus round.

Fortunes of Sparta by Blueprint Gaming

With the slot Fortunes of Sparta from Blueprint Gaming, the player dives into the mystical world of antiquity and accompanies the brave warriors of Sparta. Blueprint is actually a British software developer, but has been part of the Gauselmann Group since 2012, known for its popular Blueprint Gaming games such as Eye of Horus or Magic Mirror Deluxe 2.

Fortunes of Sparta impresses above all with its graphics. But the game has even more to offer. The slot appears in the classic 5×3 format with 20 paylines and offers several bonus games. The flaming helmet brings the Spartan Streak, where the wild symbol spreads across the middle reel. Then there is a free spin.

However, the player should pay special attention to the Omega symbol, which can bring up to 100 free spins. During the free spins round, the Spartan Streak feature is also active, which can bring huge wins.

Play your favorite slots with bonus rounds on your mobile

The era of smartphones and tablets has brought big changes to the digital world. A few years ago, mobile applications were uncommon, and developers created them to stand out. Currently, the situation is completely different. Any brand without an app also stands out, but that’s not a positive thing.

Mobile applications have allowed casinos to offer their services almost worldwide. Players can enjoy the game on the way to work by public transport or lying under palm trees on a paradise island. Mobile software can be downloaded directly from the website of a given company or a store dedicated to specific software. In the case of devices from the Apple brand, it is the App Store, for the rest of the devices, applications can be downloaded from the Google Play store.

What determines victory when playing slots with bonus rounds?

Slots are the most popular games in any casino, but many people don’t understand exactly how they work. Whether a slot has bonus rounds or not does not change the form of things. Slots use a random number generator responsible for the symbols drawn on the reels. RNG has no historical memory, meaning he does not remember previous draws. As a result, every time the drums are triggered, players have the same chances of creating a winning combination on the paylines.

The bonus round can slightly increase the RTP, or the player’s chances of winning, while luck still determines winning the slot. When playing the slot, players do not influence the final result. Only the rate and the length of the session are dependent on them. It is worth noting that slots offer the lowest chances of winning among all casino games, yet they are the most popular.

Final thoughts on slots with bonus rounds

Slots with bonus rounds can bring each participant glory in the gaming community and real money. However, financial factors are not the main reason these projects were created. Their main goal was to bring instant joy to all users.

If the participant chooses projects with bonus rounds, the player must be prepared to spin the reels and solve a few other gameplay tricks. In some cases, the player must solve puzzles or collect matching items.

If the user does everything right, getting rich quickly won’t be difficult, especially if the player develops his strategy. This is important because sometimes it’s hard to tell when the user should bet and when to play a second with bonus rounds.

But if the player does everything smart enough, he can easily get as rich as he wants. Some projects also include some elements of social interactions. The player will receive his profile if the participant registers via the developer’s website. It can be connected to social networks like Facebook. This way, the user can compete with friends when they get the highest score on the leaderboard with bonus games. For anyone who likes to be the best, it will be a good way to prove he is.

FAQ

💡 Which bonus brings the highest payouts?

It is not clear which of the available bonuses is the most lucrative; it all depends on your luck. Players often choose slots with the free spins option because this bonus usually comes with additional multipliers or wilds, increasing the possibility of hitting a high bonus.

💡 Is there a bonus option in every slot?

Most slots offer a bonus option, but sometimes it is very limited. The most advanced forms of bonuses are used in modern fictional video and progressive slots.

💡 Can the player influence the appearance of the bonus in the game?

The slots' algorithms create a random appearance for all the layouts in the game. This is similar to bonuses, which appear completely randomly, and the player cannot cause a bonus or interfere with the game.

💡 Where to find slots with a bonus round?

Slots with a bonus round are available at every online casino. There are a lot of them, so they are usually placed in a separate tab.

💡 How are bonus rounds triggered in slots?

Bonus rounds in slots are typically triggered by landing specific symbols, often called scatter symbols, in a required number or configuration on the reels. Some slots may require these symbols to appear on active paylines, while others might trigger the bonus regardless of the symbol position.

💡 Can players influence when a bonus round occurs?

No, players cannot influence when a bonus round will occur. Slot games use random number generators (RNGs) to determine the outcome of each spin, including the appearance of bonus-triggering symbols. The process is entirely random to ensure fair play.

💡 Are slots with more bonus rounds better?

Slots with more bonus rounds aren't necessarily better but can offer more engagement and excitement than those without. These features can also provide potential ways to win, which might appeal to some players. However, a slot game's overall enjoyment and suitability depend on personal preferences and playing style.

💡 Where can I find slots known for their exciting bonus rounds?

Additionally, slot reviews and casino game forums frequently highlight games with notable bonus features, making them a good resource for finding slots with entertaining and rewarding bonus rounds.

💡 Do bonus rounds affect the RTP of a slot?

Bonus rounds don't change a slot's RTP, which measures the total percentage of wagered money a slot will pay back over time. However, slots with lucrative bonus rounds might offer higher potential returns during those features, which could appeal to players looking for big wins.

💡 How can I maximize my winnings in bonus rounds?

Maximizing winnings in bonus rounds involves understanding the specific rules and features of the bonus. Knowing how to play each bonus round effectively can make a significant difference. For example, knowing whether some options are consistently more valuable in a pick-and-click game can help. Also, managing your bankroll to ensure you can play until a bonus round is triggered is crucial.
