There are many ways bonus rounds can be categorized. Still, this is often done according to their function or objectives. Let’s take a closer look at these categories.

By functions:

• Reward boosters: Reward boosters usually include multipliers that increase winnings by 2 or more times. Free spins can also be categorized in this group.
• Interactive gameplay: As the name suggests, interactive gameplay in slot machines with bonus games involves active player participation. This typically comes in the form of pick—and—click games where symbols or items are selected to reveal prizes or skill—based mini—games like aiming at targets for rewards.
• Extended playtime: Re—triggerable free spins, re—spins, and bonus wheels are some bonus rounds that can help players play longer.

By objectives:

• Win amplification: Titles with features like stacked wilds or expanded reels provide additional opportunities to increase winnings. These include those with progressive multipliers that increase with each winning spin within the bonus round.
• Skill—based bonuses: Some free no download slots with bonus games also have bonuses whose rewards depend on the players’ decisions or decision—making speed.
• Jackpot opportunities: Most often, these are jackpot bonus rounds where users can win one of several jackpots through various activities – pick game, wheel spin, etc.

How to Activate Bonus Rounds

Although there is no universal rule for how bonus rounds are activated in these games, a particular pattern is observed in most of them. In most cases, it’s about the appearance of so—called special symbols in certain positions and combinations.

For instance, whenever you play free slots with bonus games online, and these titles have free spins, you usually have to get three or more Scatter symbols anywhere in view to launch a round of free spins.

Sometimes, you can activate re—spins when you get a single Wild symbol. In most cases, they will expand and initiate another re—spin if you get one more Wild symbol. When it comes to cascading wins (tumble feature), they continue as long as you get new winning combinations on the gaming panel.

It’s also common for these slots to offer fixed jackpots when you hit a combination of 5 bonus symbols on a payline. Let’s not forget that there are free online slot machines with bonus games that randomly trigger bonus rounds. This means there’s no need for specific symbol combinations to benefit from these unique features.

You can find more information about these things in the slot’s paytable or help section, where the bonus features, including how to trigger them, are explained.

How to Play Bonus Rounds for Real Money

There are many reasons why a player would want to play free slots. Of course, there are just as many reasons why some prefer playing slots for real money. Both options offer great excitement and enjoyable moments on the screens. To better understand ​​the differences, we decided to highlight them through the table below.

If you want to play for real money, it’s best to check our casino reviews. This is the best way to choose a trusted online casino because we analyze and rate every aspect of casino operations.

Different Bonus Games Features

Just like graphics, themes, sound effects, and reels, bonus rounds are essential to slot games. Although not all slots are free slot machines with bonus rounds, more than 95% have at least one special feature.

With the help of bonus rounds, you get a break from regular gameplay. All this makes slots more attractive and less repetitive. Of course, in addition to increasing the excitement, they also bring more chances to win.

Given that software providers try to produce unique and stand—out games, it is no wonder that there are different types of bonus rounds. Below, we will present a list of all the notable options that you have in free slot games with bonus features. Additionally, we will focus on the five main features in the following paragraphs.

• Free Spins: With the help of this feature, players get 5, 10, or more spins at no additional cost. The potential wins are based on the initial bet.
• Gamble Feature: The gamble feature becomes available in many slots once you hit a winning combination. It’s usually a card guessing game that can double or lose your prize.
• Pick Me: Your objective is to pick an object or an item (or a few objects/items) to reveal a prize.
• Wilds: These special symbols substitute for all regular paying symbols to help you create a winning combination.
• Expanding Wilds: They act the same way as the Wild symbols but also expand to cover all positions on the reel where they appear.
• Re—Spins: Thanks to the re—spins feature, you get a free spin on one or more reels while at least one other reel with its symbols remains.
• Multipliers: These symbols help you multiply your winnings as long as they participate in a winning combination. Some slot games with bonus rounds have progressive multipliers, which grow with every consecutive win.
• Hold n’ Spin: This feature lets you choose specific symbols on the gaming panel to remain in their positions before spinning, making it easier to hit winning combos.

Free Spins Feature

Even though not all slots with free spins are the same, in most cases, you need three or more scatter symbols in any position on the gaming panel to activate a round of free spins. Players get 5, 10, or more spins free of charge. Some providers spice up these rounds with mini—games or multipliers, allowing players to increase their winnings further.

Keep in mind that the free spins feature in slot machines is often confused with other bonuses like online casino promotions involving free spins on various slots. To learn about the differences and discover the best free slot machine games with bonus rounds like this, visit our corresponding page.

Pick Me Feature

Unlike free spins, which don’t require any action from players, there’s a certain level of interaction regarding the pick me feature. Namely, this bonus allows players to choose items or objects. Sometimes, they must reveal symbols until they find three matching ones to get a prize. In other cases, they can select a single object or a few of them and receive the prizes highlighted on these objects.

Depending on the free slot games with bonus rounds you have chosen, the prizes can cover anything from cash rewards and multipliers to free spins and jackpots. In any case, this is an exciting interactive feature that’s becoming more popular.

Scatters Feature

Generally, a scatter symbol helps players activate bonus rounds. However, in some cases, it’s only a symbol that promises payouts regardless of its position on the reels. You still need three or more scatters to hit a winning combination, but they don’t have to be on a specific payline or pattern.

When they activate bonus rounds, they usually lead to rounds of free spins. Sometimes, they can launch a pick me feature or another special feature. As expected, these symbols typically feature some of the main elements of the story behind the slot.

Wild Symbol Feature

Another popular symbol you can find when you play many free slots online with bonus games is the wild symbol. In the past, it was usually represented by a joker. Today, it comes in many forms, primarily related to the game’s theme, such as its main protagonist.

Wild symbols replace standard paying symbols when they can help players complete a winning combination. They can also increase the wins when you already have a winning combo.

Sometimes, wilds carry multipliers to boost your wins. Lastly, specific patterns with wilds can trigger re—spins and other bonus features.

Hold n’ Spin Feature

At the end of this list of main bonus features, we have the Hold n’ Spin feature. You can activate it by landing certain special symbols on the reels. After activation, the symbols that activated it remain in place, or it is left to the player to choose which symbols will remain. In contrast, the rest are replaced by new ones. In many free casino slots with bonus rounds of this type, only special symbols appear on the matrix during this round. Players get three re—spins with the possibility of repeating them.

This bonus is quite popular, which is reflected in the titles of many games that contain this phrase. This is not surprising, considering that the bonus adds interactivity to the game.

Bonus Rounds Slots Comparison

The large number of bonus rounds can be confusing for some readers. That’s why we decided to create a table that allows users to compare the different bonus rounds in terms of their type, activation frequency, and maximum win limit.

Top New Free Slots with Bonus Games Over the Year

Several newly released free slots no downloads, with bonus rounds marked this year. Before we describe these titles, we would like to remind you that SlotsUp has a special page dedicated to new games. This page highlights the newest and most interesting slots. It also provides an opportunity to try them for free.

1. Outsourced: The Outsourced slot by Nolimit City has a futuristic theme and a unique design. This game, with an unusual 4×4 grid and 256 paylines, includes innovative features like God Mode, xWays, and Print Spins. So, it’s no wonder it won the “Game of the Month” title in SlotsUp rating in August.
2. Angel vs Sinner: From Pragmatic Play comes Angel vs Sinner, another interesting title with exceptional audiovisual elements and a memorable theme. It has an excellent maximum win limit of 15,000x the bet and a high RTP of 96.56%. Let’s not forget that it was in the top 3 runner—ups for the “Game of the Month” in SlotsUp rating in September.
3. Mighty Wild: Panther Grand Diamond Edition: This slot by Wazdan has an uncommon gaming panel with 15 independent reels. Its most interesting and potentially rewarding feature is the Wild Rampage bonus game.
4. Fortune Tree of Wealth: The Fortune Tree of Wealth slot by Wizard Games is one of the new free slots bonus games with a somewhat classic set of 4 reels, 3 rows, and 15 paylines. Lock—n Spins, a wild symbol, and Coin Drop are this slot’s main special symbols and features.
5. Fishin’ Bear: 3 Oaks lets players join a bear on its fishing expedition with the help of the Fishin’ Bear slot. Besides the beautiful cartoony visuals, this game includes a round of free spins, a bonus game, and other attractive bonuses.

How Do We Rate

At SlotsUp, we have developed a system that allows us to impartially rate all the slot games we come across. This system is based on all team members’ many years of experience in this industry. Our review policy related to online casinos is similar.

We consider all aspects of the functioning of each slot to get a realistic assessment of its value. Only slots with bonus rounds and high scores in all crucial departments rank high on our list and are among the recommended titles. This way, every player can make an informed choice.

The specific factors that influence the rating are the following:

• RTP Score: One of the first things we evaluate is the slot game’s RTP (Return to Player). Of course, the higher the RTP, the better. Games with 96% or more receive the highest ratings, while those with an RTP below 90% receive the lowest.
• Features Rating: Evaluating free casino slot games with bonus rounds without considering their features would be a big mistake. Our team looks at not only their number but also their quality and innovation. Titles with standard features enriched with at least one uncommon feature like Megaways, Bonus Buy, or cascading reels, bringing the total number to over 4, are ranked higher.
• Game Mechanics Rating: Game mechanics also play an important role in influencing the overall gaming experience. Among the best games, you will find slots with lots of bonuses, interactions between symbols, complex and interesting rules, and a high level of player engagement.
• Assessment of Win Potential: We also rate slots based on their win potential. To determine it, we consider the maximum win limit and the volatility level. If volatility is high and the maximum win is limited to at least 5,000x the player’s bet, then the slot gets the highest score in this regard.
• Theme, Graphics, and Sound Effects Rating: The audiovisual experience and story also play a role in ranking free slots with bonus games. The best titles are those with modern, high—quality visuals and sounds and fun game themes.
• First 100 Spins Rating: Our team members run a test that includes 100 spins on a specific title to determine what a slot offers. The scores are higher if they have high payouts and activate attractive features.
• Provider Reputation Score: Finally, we also consider the software provider behind the slot game. Providers with an excellent reputation, valid licenses, and quality slots get excellent grades.

Responsible Gambling: Tools and Tips

At SlotsUp, we believe gambling is all about having fun. This is why we encourage and support responsible gambling practices, including setting time, deposit, and loss limits and providing access to tools and features that promote safer habits.

Our team compiled resources to support players, including tools for safer gambling. Additionally, we have a page with a dedicated guide to responsible gambling.

Whenever users decide to play for real money, they should choose carefully, follow the responsible gambling rules, and ensure the casino is safe and legitimate. One of the best ways to do this is to explore our casino, where they can learn more about online casinos and gambling.
