A majority of online slots now come with one or more bonus modes, adding an extra layer of entertainment to the game. With that being said, some bonus rounds offer more than others, and of course, like with any online slot, personal preference goes a long way. Regardless of whether you’re looking for modern bonus modes with unique mechanics or more traditional free spin rounds, Heart Bingo has got you covered.
We share a selection of the best slots with bonus rounds while also explaining the most popular features of each!
What Are Bonus Rounds In Slots?
Bonus rounds are additional modes that can be found in online slots, often activated by landing three or more scatter icons at the same time. They typically offer a range of new mechanics or simply offer the player with a number of free spins. Many online slots with bonus modes will also have their appearance changed slightly when the round triggers.
Top 15 Slots With Bonus Rounds To Play At Heart Bingo
While there is a huge array of online slots with bonus modes at Heart Bingo, here’s a quick look at 15 that stand out from the crowd!
1. Immortal Romance
First up on this list is Immortal Romance, a release by Microgaming that features a vampire theme. There are two bonus features in this game, one of which can turn any number of the five reels completely wild.
As for the other bonus, it’s a free spins mode that comes with a host of different combinations, including win multipliers and various spin modifiers!
2. Age of the Gods: God of Storms
The Age of the Gods: God of Storms comes with a traditional appearance that features a view of a Greek city. A total of four jackpots can be found in this release, alongside two variations of wild.
One of these wilds can be blown by Aeolus, the Greek God of storms, causing it to cover multiple reels. A series of respins will be awarded, and after each one, the wild will be moved to one position to the left. This continues until the wild is blown off the board from reel 1.
3. Bigger Bass Bonanza
When it comes to fishing-themed slots, Bigger Bass Bonanza is one of the leading titles. It comes with a classic underwater scene in the background, with 5 reels, 12 paylines, and a minimum stake size of 0.12 per play.
This release has been optimised for mobile devices and features the signature ‘Big Bass’ bonus round, where fisherman symbols are collected to award more spins and win multipliers. The collect mechanic remains active in this release, too!
4. Rainbow Riches
Rainbow Riches is a creation from Barcrest that revolves around a ‘Luck of the Irish’ theme. It’s a traditional slot that features everything players would expect, such as Leprechauns, rainbows, and pots of gold!
There are three different bonus modes in Rainbow Riches, all of which are triggered by landing 3 of the corresponding scatter icons landing simultaneously. Each bonus has something slightly different to offer players, including a wheel spin and a ‘Pick Me’ style round, where players can select one of three wishing wells to reveal the potential winnings.
5. Money Train 3
The Money Train 3 slot features a wild western theme, just like the other titles in the series. Players can also find the same respin-based bonus mode in this release too, although some new twists have been added to keep things fresh!
Landing three scatter icons will trigger the round, with players receiving three respins. When a new icon lands, it will become sticky and the number of respins will reset. This continues until no more respins remain, at which point all icons on the board are totalled up, multiplied by the bet size, and awarded to the player.
6. Age of the Gods: Wheels of Olympus
Another title from the Age of the Gods series finds its way onto our top 15 list. When it comes to jackpot slots, there are few releases that can stand up to Age of the Gods: Wheels of Olympus, with this game also being jam-packed with bonus features.
There are three different wheels at the top of the screen, which can award free spins, a respin with 4 or 5 wilds in play, a fixed value based on the stake size, or an upgrade to the next wheel. As for the jackpot round, this can come into play at random during any spin, regardless of the stake size.
7. Ted Megaways
Based on the infamous Ted movie, this title was created by Blueprint Gaming and comes with plenty of references to the film. Some of these references can be found within the various bonus modes, such as ‘Thunder Buddies’, which is the equivalent of a free spins round in Ted Megaways.
8. Stargate Megaways
As you can probably tell, Megaways slots are incredibly popular, with yet another making it on our list. Stargate Megaways comes with a Sci-Fi theme, a cascade mechanic, and up to 117,649 active paylines per spin.
Bonuses in this game consist of 5 different spin modifiers that can be activated through the Stargate trial. There is also a free spins mode that can have a variety of added features, depending on what players find during the pre-bonus ‘Pick Em’ mode.
9. Starburst
Starburst is an online slot that has been popular for many years. It’s set in outer space and features an array of bright gemstones as the symbols. There is no free spins bonus in Starburst. However, there is a respin mechanic that can be triggered through the rainbow wild symbol!
10. Book of Dead
Set just outside of an Ancient Egyptian tomb, the Book of Dead slot is a visually appealing release that features an assortment of pillars on either side of the board.
Many players will already be familiar with the bonus mode in this title, which is similar to other ‘Book of’ games. The round can be activated by landing three or more scatter icons, with a special expanding symbol being selected at the beginning of the round. This chosen icon can ignore paylines to form combinations and should a match be created, the symbol will expand to fill the reel.
11. Sahara Riches Cash Collect
At number 11 is Sahara Riches Cash Collect, a game that features a collect mechanic and four different jackpots. These jackpots are fixed at 20x, 50x, 200x, or 500x the stake size and can be awarded through the aforementioned collect feature. Interestingly, the free spins mode is also triggered in this way!
12. Dynamite Riches Megaways
In addition to the Megaways mechanic, this release features an assortment of bonus features which can be activated by filling a meter. Dynamite Riches Megaways has four segments in total, which are unlocked incrementally by utilising 15 wilds during the same spin.
Each segment that is completed will award its own spin modifier, which can include multipliers and giant wild icons!
13. Game of Thrones 243 Ways
The Game of Thrones 243 Ways release comes with a minimal appearance, with a focus being put on the gameplay itself. Just like in other online slots, getting three or more scatter icons on the same spin will trigger the main bonus mode. However, in this title, players can pick between four combinations of varying spin amounts and multipliers!
14. Vikings Go to Valhalla
Released by Yggdrasil Gaming, Vikings Go to Valhalla is an immersive slot that features a dark background and vibrant symbols.
One of the added features included in this title is ‘Viking Battles’, a unique mechanic that is triggered when any Viking symbol creates a combination. Players can also find a free spins mode, a wheel spin bonus, treasure chests, and much more!
15. Fluffy Favourites Fairground Jackpot
Last but not least we have Fluffy Favourites Fairground Jackpot, a colourful title that comes with a rollercoaster and a circus tent in the background. One of the most notable features in this game is the progressive jackpot, however, free spins and ‘Pick Em’ modes are also available.
Different Types of Slot Bonuses
If you’re struggling to pick an online slot with a bonus mode that matches your preferences, it’s important to know the differences between the rounds themselves. Here are the most popular options:
Free Spins vs Respins Features
A free spins bonus mode will award a specified number of plays that come with no cost. On the other end of the scale, a respin feature will typically award a predetermined number of spins, usually three, with this figure resetting when certain conditions are met.
Most of the time, respin modes come with sticky icons that show fixed values. When a new one appears, it will lock in place before the number of spins is reset. These rounds end when no more spins remain, with all values on the screen being totalled up and awarded.
Pick ‘Em Feature
While these bonuses can differ slightly, they all revolve around players selecting a certain item to reveal the potential winnings beneath. These can be linked to jackpot slots too, with each item on the screen linking to a different prize.
Spin the Wheel Feature
As the name suggests, this involves the player spinning a wheel to determine their potential winnings for the round. Segments of the wheel can include multiples of the stake size, spin modifiers, or a different bonus mode!
Instant Win
These types of features are relatively uncommon in modern slots. However, they can award players with a multiple of their stake size, should certain criteria be met. In some cases, these potential winnings will even be awarded totally at random!
Progress Bar
When certain things happen on the board, such as using wilds to create matching combinations, segments of a progress bar will be filed. As more portions of the progress bar are filled, players may trigger the free spins bonus round or unlock a modifier.
These progress bars can accumulate over the course of a session or be dependent on each spin, so be sure to check the rules carefully before playing!
