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.

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

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.

And with a high RTP of 96.21 percent, 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.

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 that is 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.

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 and there’s no limit on how many times they can be retriggered, as well as the Random Multiplier feature, which can show up at any point.

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.

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.


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

You can land a mega multiplier of up to 27x! If you’re lucky enough to get the multiplier, you’re in for a huge payday.

Similarly to Cleopatra, there are also some new 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 on the European continent 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.

Rainbow Riches

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.

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 percent, which is above average for land-based slots.

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

You can get up to a maximum of 80 free spins.  

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.

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.

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.
