Slots with bonus rounds are arguably the best online slots available. Bonus rounds like free spins, pick-me bonuses, mystery bonuses, drops & wins, and wheel of fortune-like bonuses can all increase your winnings massively.

Without these bonus rounds, most slots would be pretty dull. A fun and exciting bonus feature can make or break an online slot machine, and as of late, almost every new release has at least one sort of bonus feature.

In this article, we will cover 10 slots with great bonus features that are definitely worth a try. These slots come from the world’s best online casino software providers, such as NetEnt, WMS, Microgaming, and Yggdrasil, and all have fantastic bonus mechanisms that will keep you entertained.

1. Dead or Alive by NetEnt

The Dead or Alive bonus feature definitely belongs within our top 10 slots with bonus rounds, as it gives you a chance of winning gigantic amounts of money with its bonus game. Whenever you get to spin 3 or more scatter symbols, the free spins bonus round will be activated. You will receive 12 free spins, and all payouts will be doubled. However, that’s not all.

Every wild that shows up on the reels will become sticky. If you manage to get a wild on each reel, you’ll receive another 5 free spins. When a full payline is filled with wilds, you’ll be handsomely rewarded with 3,000 times your initial bet.

2. Fruit Warp by Thunderkick

Fruit Warp by Thunderkick is a truly unique slot that doesn’t look like any other online slot machine out there, and the same can be said about its bonus game. During the game, all sorts of fruits are thrown at you. Whenever five or more similar fruits are thrown, the free spins bonus round will be triggered.

With this bonus round, you keep spinning as long as you receive at least one of the fruits that triggered the bonus round in the first place. Apart from winning money, a multiplier keeps increasing. Additionally, you have a so-called lifesaver that you can use whenever you don’t receive the needed fruit to keep on spinning.

3. Raging Rhino by WMS

Raging Rhino is undoubtedly one of the best high-volatility slots WMS has ever created. The game has an African Savannah theme and 4,096 ways to win. However, it is the bonus round that is the most interesting part of the slot.

Whenever you get to spin 3 or more scatter diamonds, you’ll win 15 free spins. During the free spins, stacked and wild symbols will fill the reels and wild symbols will act as 2x or 3x multipliers as well. As wilds can appear on the second, third, and fourth reels, you can potentially get a multiplier of 81x in total.

Add to this the fact that two or more scatter diamonds will net you another 5 free spins, and it becomes clear that Raging Rhino’s bonus round can be very lucrative indeed.

4. Jack and the Beanstalk by NetEnt

The Jack and the Beanstalk slot is based on the popular English fairy tale. The slot has been out for quite a while but is still one of those with an incredibly exciting bonus round. Whenever you get to spin 3 or more scatter symbols, you will receive 10 free spins.

Before the free spins bonus round starts, a giant vine will grow that takes both Jack and the player to a whole new playing field in the sky.

During the free spins, a walking wild feature will be activated. The walking wild starts at the right side of the screen and moves one square to the left with each spin until it leaves the game area. You will continue to receive free spins as long as at least one walking wild is still visible on the playing field.

Apart from the walking wild feature, there will appear keys on the fifth reel. The more keys you save up, the more wilds you will receive. Once you have collected all 5 keys, all wilds turn into expanding walking wilds resulting in potentially gigantic wins.

5. Montezuma by WMS

The Montezuma slot by WMS has a great Aztec theme, but an even greater bonus round that can reward players with unlimited respins and 10x multipliers. Whenever you spin 3 or more scatter symbols, the wheel of Montezuma is activated.

The first spin decides how many free spins you receive in total, which can vary from 3 to 25. During every free spin, a mini wheel is spun that dictates the multiplier for that particular spin. This multiplier can range from 2x to 10x. If you happen to spin 2 or more scatter symbols during the free spins mode, you’ll receive a retrigger and get to spin the Montezuma wheel again. Whatever multiplier you get will be added to the current multiplier, which can lead to massive 10x multiplied wins.

6. The Wish Master by NetEnt

The Wish Master by NetEnt is a typical high-volatility slot. Its base game isn’t that interesting if you’d ask us, but its bonus round makes up for this perfectly well. The Wish Master is all about the genie in the bottle and the bonus boosters that come out. If the bottle shows up on one of the reels, the bonus round starts. The bonus round includes 10 free spins with a unique randomly chosen booster that can include extra wilds, expanding wilds, or multipliers.

The best part is that you can get multiple boosters when you spin the bottle again during the bonus round. You can have 3 active bonus boosters in total, which can lead to substantial wins.

7. Guns N’ Roses by NetEnt

Gun N’ Roses is a NetEnt slot released in 2016 that is based on the famous rock band and features a grand total of 6 bonus rounds. The best bonus round of the slot is undoubtedly the Crowd Pleaser Bonus. Whilst listening to the Guns N’ Roses soundtrack, you activate this bonus round by spinning 3 scatter symbols.

Once you’ve spun 3 scatter symbols, you get to spin a Guns N’ Roses wheel-of-fortune. If the wheel stops at the Crowd Pleaser Bonus, you are taken to a new screen, where you have to click on rock band items, such as Gibson guitars, the famous Axl Rose flute from Paradise City, and a cymbal. Behind the symbols are hidden credits.

Additionally, you get to earn extra picks or Free Legend Spins. If you collect enough credits, you continue to the next stage. If you manage to collect 3 Free Legend Spins symbols, you also pass this bonus round, and all won credits are doubled.

The most unique thing about this bonus round is that it is a multi-staged pick-me bonus, which you won’t often encounter at other online slots.

8. Golden Fish Tank by Yggdrasil

Yggdrasil is known for creating slots with high-quality graphics. However, with Golden Fish Tank, the studio has proven that it can also release slots with captivating bonus rounds.

The Golden Fish Tank bonus round consists of both free spins and so-called feature picks. The more scatter symbols you spin during the base game, the more free spins and feature picks you are granted.

These feature picks will award you with all sorts of extra perks like more free spins, multipliers, stacked symbols, extra wilds, and other symbols transforming into wilds.

9. Bier Haus by WMS

Bier Haus by WMS is an Oktoberfest-themed slot which has a unique bonus round featuring sticky wilds and retriggering free spins. The game doesn’t have any scatter symbols, though. You trigger the bonus round by spinning 5 Heidis on any of the pay lines.

The bonus round starts with between 5 and 80 free spins. Whenever the Heidis carry beer glasses, they become sticky wilds for the rest of the bonus round duration. Added to this, you can trigger even more free spins that can also become extra sticky wilds. Ideally, you get to fill the entire screen with Heidis carrying beer to land a massive win.

10. Immortal Romance by Microgaming

Immortal Romance by Microgaming is a 243-payline slot that is among the most popular casino games in UK casinos. Not only can players win up to 12,150 times their bet per spin with this slot, but it also has a 31,21% hit rate and multiple bonus round features.

The first bonus round that you can trigger with Immortal Romance is the Wild Desire feature which will reward you with up to 5 wild reels. However, the real big bonus round is triggered whenever you get to spin 3 or more lion door knocker symbols.

Once this bonus round is triggered, you get to enter the Chamber of Spins and select one of four characters. Each character gives you a certain amount of free spins and a special perk.

  • Amber – rewards you with 10 free spins with a 5x multiplier.
  • Troy – rewards you with 15 free spins with the Vampire Bats feature. Vampire Bats will turn symbols into 2x and 3x multipliers. If you get two on the same symbol, it will turn into a 6x multiplier.
  • Michael – rewards you with 20 free spins with the Rolling Reels feature, which will cause consecutive wins to increase multiplier values up to 5x.
  • Sarah – rewards you with 25 free spins with the Wild Vine feature. The Wild Vine symbol is key on reel 3, and it will randomly change other symbols into wilds.

Are Slots With Bonus Rounds Worth It?

As you can see, modern online slots can have exciting bonus rounds that work differently. Some just have free spins, whilst others allow you to choose from a series of bonus perks. There are even slots with multi-staged bonus rounds as well. Note that you can try out most of the slots mentioned for free, thanks to the demo versions, to familiarize yourself with them before putting your hard-earned money on the line.
