The Best Slot Machines With Bonus Games

People like different games for different reasons, but the most popular slots are usually the ones with bonus games.

These juicy extra features can help you become an instant millionaire, so let’s check out some of the best slot machines with bonus games, both online and at land-based casinos.

Best Online Slots With Bonus Games


Starburst slot game

A timeless classic that’s super easy to play and great for both big and small bankrolls.

As far as slot games go, it’s quite basic. However, it offers high payouts and the opportunity to win big with the Starburst Expanding Wilds.

When the Starburst Wild appears on the reels (it can appear on reels 2, 3 and 4), it helps to create a winning combo by replacing other symbols. Any Starburst Wilds will also expand to cover the whole reel. You then get a respin with the Wild reel/s.

If you are lucky enough to land five of the Wilds, you’ll walk away with the juicy jackpot!

Starburst has an RTP of 96.09% and a medium variance.

Book of Dead

Book of Dead slot

This Egyptian-themed slot is best for casual players, as the maximum betting amount is lower compared to other games.

That said, you can still win up to 250,000 coins in Book of Dead thanks to its rewarding free spins bonus game.

Landing 3 or more Book scatter symbols will unlock the bonus and take you to the exciting Sacred Chamber bonus round with 10 free spins. It’s possible to re-trigger the free spins infinitely, plus, alongside the unlimited spin, one random feature will also be an expanding symbol to boost payouts.

With a high RTP of 96.21%, it’s worth checking out.

Immortal Romance

Immortal Romance slot

This vampire-themed 243 ways slot game from Microgaming has plenty of ways to win and some incredible bonus action to sink your teeth into.

It has a four-level bonus round – the Chamber of Spins – that unlocks as you play.

  • Your first bonus is 15 free spins that multiplies winnings by 5x.
  • Once your Chamber of Spins meter reaches five, you’ll unlock 15 free spins and the Bat feature.
  • At 10, you’ll activate 20 free spins with a Cascading Reels feature.
  • After the 15th trigger, you unlock 25 free spins with a Wild Vine feature.

Alongside the generous 96.85% RTP, the variance is extremely high. You will have regular small wins but need the bonus games for bigger payouts.

Overall, expect tons of free spins and wilds features, with the chance to win its mega 3,645,000-coin jackpot.

Bigger Bass Bonanza

Bigger Bass Bonanza slot

This slot is a follow-up game to Big Bass Bonanza. It’s pretty similar to the original, give or take a few extras, like the expanded reel set and earning potential.

You’ll find a solid free spins feature with rewarding wilds, plus a fish scatter worth 4,000x your bet.

This free spins bonus is the center of the game and the path to bigger wins. You receive 10, 15, or 20 free spins on 3, 4, or 5 scatter symbols. During free spins, wild symbols help to stack wins, and the angler character collects the wilds. Every 4th wild that lands will deliver 10 more free spins, with multipliers of 2x, 3x, or 10x.

It has a high RTP of 96.71% and high volatility.

Fruit Party

Fruit Party slot

Although Fruit Party looks pretty plain and basic, it offers some nice features and a great jackpot prize of 5,000x your bet.

You can get free spins with no limit on how many times they can be retriggered, as well as the Random Multiplier feature, which can show up at any point.

The base game’s Random Multiplier feature offers 2x boosts, which also appear during the Free Spins round. In this bonus game, you get 10 free spins that enable stacking multipliers. Here, you can build random multipliers up to 256x your stake.

Fruity Party has a RTP of 96.47% and medium variance.

Wheel of Fortune

Wheel of Fortune slot

A back-to-basics video slot that has become a cult classic, Wheel of Fortune delivers big wins on a Tripler Big Spin feature.

Yes, the game borrows the name from the iconic game show, but actually has little resemblance to it. Featuring 5 reels and up to 720 paylines, Wheel of Fortune has a higher variance and slightly above-average RTP of 96.1%.

There are several bonus games to sink your teeth into, including Wild Bonus and the Mini Wheel. You can also unlock the Wheel of Fortune Bonus for 5 symbols that could land 10,000 coin wins.

The Triple Extreme Spin Bonus allows you to choose a random envelope, which then provides a multiplier on spins. These multipliers can lead to the top payout of 5,000,000 coins.

Divine Fortune

Divine Fortune slot

Divine Fortune is a popular progressive jackpot game from NetEnt. The local progressive jackpot opens by getting three gold coins and has an average payout of around $115,000.

There is a standard RTP of 96.59%, although the jackpot is 4.07%, so the RTP without bonus is 92.52%. Even in the non-jackpot game, big wins can happen thanks to four different bonus rounds.

Falling Wilds Respins can happen when a wild hits the reels. It will shift one position and provide a Respin. Overlay Wilds can land on top of a wild and expand across the whole reel. The Divine Fortune free spins round delivers up to 12 free spins, and the Falling Wilds Respins and Overlay Wilds are available during free spins.

Best Land-Based Slots With Bonus Games

Many of the slot titles below are also available to play online.

Whether you prefer to play from the comfort of your own home, on the go, or in your local casino, there’s an option here for you!


Cleopatra slot

This Egyptian-themed slot machine has stood the test of time – and for good reason.

Players can trigger a free spins bonus round where 15 free spins are up for grabs with a 3x multiplier.

During this bonus round, you can trigger more free spins, up to a maximum of 180.

It’s one of the more simplistic bonus features around but the payouts make it worthwhile.

There have been a number of follow-ups to the game, including Cleopatra Plus, Cleopatra Mega Jackpots and Cleopatra Gold.

Whether it’s the classic or a newer rendition, there’s going to be a version you’ll love.


Zeus slot

Another classic favorite, this Greek mythology-themed slot offers a 5-reel, 30-payline game where you can win up to 100 free spins as a bonus.

The potential wins from those free spins have helped propel the slot into slots immortality.

Follow-up releases of Zeus II, Zeus III, and Zeus: God of Thunder have been equally well received by slots players.

10, 25, or 100 free spins are available for 3, 4, or 5 scatter symbols, respectively, and you can re-trigger unlimited times.


Buffalo slot

The legendary Buffalo slot from Aristocrat is a superbly volatile game with 1,024 paylines.

This means you can win money really quickly and those wins are easy to come by, but your bank balance can also plummet quickly too – so be careful.

The bonus round in this game is where you can really make your money. You get free spins, which might sound standard, however, they have a twist.

During the Free Spins bonus, you get up to 20 spins with wild symbols up to 3x. A wild symbol helps to potentially stack multipliers up to 27x, and you can also re-trigger the free spins.

Similarly to Cleopatra, there are also some newer versions of the game that offer exciting twists on the original.

Book of Ra

Book of Ra slot

This 5-reel, 10-payline slot has proved particularly popular in Europe, with Novomatic really pushing it in a number of countries in that region.

The jackpot is great on this game, though with just 10 paylines, you will need to rely on Lady Luck to help you win.

The bonus round is packed with expanding symbols, which is ideal for bringing in extra wins.

10 free spins are available, with up to 5,000x your bet up for grabs if the whole game grid has the expanding symbol.

Wins are not frequent due to the extreme volatility and 95.1% RTP, but when they do land, the payouts can be big.

Rainbow Riches

Rainbow Riches slot

Initially, players were critical that Rainbow Riches didn’t offer a free spins bonus round.

However, when it soon became obvious how incredible the Pots of Gold Bonus, Road to Riches Bonus, and Wishing Well Bonus were, it was clear the lack of free spins didn’t matter.

And the jackpot is insane!

It’s no surprise that this game spawned several sequels online including Rainbow Riches: Reels of Gold and Rainbow Riches: Pick ‘n’ Mix.

Rainbow Riches is a medium volatility game with an RTP of 95.1%.

Bier Haus

Bier Haus slot

The graphics and animations might be a little dated, but Bier Haus continues to be a hugely popular title among slots players.

The Oktoberfest-themed title has a great RTP of 96.28%, which is above average for land-based slots.

The free spins feature is its biggest feature, which doesn’t sound as impressive as other games on this list, but will be huge if you land it. 

You can get up to a maximum of 80 free spins.  There are also Persisting Wilds (sticky wilds) that lock a position for the whole bonus round.

88 Fortunes

88 fortunes slot

The free spins bonus round and the chance to hit four progressive jackpots mean you’ve got a high win potential in this game, however the game is very volatile.

Fu-Bat is the jackpot feature where you try to match Baby symbols for 1 or 4 jackpots.

Keep your eyes peeled for the Gong Scatters, as if you land three on adjacent reels you’ll trigger the bonus game with 10 free spins. The features also replaces low-value symbols with high-value symbols.

88 Fortunes has an RTP of 96% for the non-jackpot game.

Try Before You Buy

If you want to get a feel for any of these games before you play them at the casino or online, we suggest trying out the free version first.

This way you can get a sense of their volatility, how they work and whether you think it’s worth your while before risking any real money.
