Which are the best slot games to feature bonus rounds?

There are thousands of online slot machines with bonus games that you can play right now, but if you want the best, look no further than these options.

Starburst

Starburst is one of the most popular slot games of all time. Released in 2012, the slot has been sent into orbit with a galaxy of gems spinning across the reels for over a decade. In the base game, it has a solid offering of five reels and three rows, with a total of 10 paylines but its bonus features are truly out of this world.

It starts with the “Win Both Ways” feature, which turns the traditional slot format on its head. Many games require you to match symbols left to right, but Starburst’s Win Both Ways mechanic allows you to do it in either direction.

Wild symbols are common in many slots, but they form a big part of Starburst’s bonus functionality. Whenever one appears on your screen, it will expand to fill the entire reel, giving you more opportunities to create matches across all the paylines.

If you want even more action, Starburst’s Wild symbols also trigger the Respins bonus feature. The expanded symbol will be locked into place on the reel whilst you get to spin up to three times more.

Book of Dead

Rich Wilde is a popular feature within slots and The Book of Dead slot sees him take on the sands of Ancient Egypt. Its base game uses a 5x3 reel layout, with each one lined with vibrant and golden symbols.

As you spin, you’ll quickly see why The Book of Dead is one of the best slot machines with bonus games. The book symbols that slide their way onto the reels are your key to unlocking these features.

These books act as both Wilds and Scatters, meaning they can simultaneously substitute for other symbols to make winning combinations whilst also paying out just for their presence.

Get three or more books and you’ll trigger ten free spins. During this bonus, the game will pick a symbol that will expand on any reel it lands to unlock further wins. To add to the gameplay further, Scatter symbols can appear during these bonus spins. Land three or more and ten more will be added to your free spin count.

Fishin’ Frenzy

Grab the rod and reels for Fishin’ Frenzy. This seafaring slot has a base game with five reels and three rows swimming with fish, boats, and angling-themed symbols.

In addition to these standard ones, the Scatter symbols play a big role in Fishin’ Frenzy. Catch three on the reels and you’ll unlock 10 free spins, reel in four at once and you’ll bag 15, and get five bites at once and you’ll be spinning for free 20 times.

Helpfully, the Scatters don’t need to be lined up, all that matters is they’re present somewhere on the reel.

The free spins in Fishin’s Frenzy are different to many other slot machines with bonus games, however. The “Fishing For Wins” feature really leans into the angling theme by placing fish symbols with price tags on the reels as you spin. The game’s angler will occasionally cast his line out to reel in some of these fish, with the corresponding figures adding to your win total.

Fluffy Favourites

If an original classic is what you need, then Fluffy Favourites is the online slot machine with bonus games for you. Its base game looks pretty standard, albeit with a selection of stuffed toys appearing as symbols that race along the reels with each spin. However, don’t let that fool you, Fluffy Favourites has some unique bonuses that you can’t find in other slots.

The Toybox Pick bonus game is unlocked by landing three or more of the claw Scatter symbols on the reels. In this mode, you’ll receive a pick for each Scatter you landed on the reels, with a maximum of five.

This bonus feature resembles the classic grabber claw games that line seaside arcades up and down the country. However, in Fluffy Favourites, you’re trying to pick out the best bet multipliers. Every pick will pull up a toy, which has a random multiplier assigned, up to a maximum of 100x. At the end of the round, your picks are added together to determine your win.

Bonanza

Bonanza is a slot with a unique design that puts a spin on the gem-themed genre. But its countryside aesthetic and mining concept in the base aren’t what make it a top slot machine with bonus games.

Firstly, Bonanza uses MEGAWAYS, a mechanic that increases the number of paylines across its six reels to as many as 117,649. It also offers many of the typical Wild, Scatter, and Multiplier features that give you additional ways to win with every spin.

If free spins are your thing, then Bonanza also has you covered. Just land four Scatters on the reels in a single spin and you’ll bag 12 free spins, with even more added for every additional Scatter you land.

But Bonanza’s unique bonus feature comes in the form of “Reactions”. For every win, the winning symbols are removed from the reels and replaced with new ones, providing a second bite at the cherry. This will continue going until no new winning combinations are made, which can lead to a real bonanza of bonus wins.

Legacy of Dead

Legacy of Dead is a follow-on from The Book of Dead slot game. For that reason, you’ll notice it looks and feels very similar.

The bonuses in Legacy of Dead will also have a familiar feel to them, though this game boasts a larger maximum payout at up to 5,000x.

Triggering the bonus requires you to land three or more Scatter symbols on the reels in the base game. Doing so unlocks you 10 free spins, again with a random symbol selected to expand across each reel it lands on.

Rainbow Riches

Rainbow Riches is an Irish mythology-themed slot game with a base that features 20 fixed paylines across its 5x3 reels. The main highlight of the game is located in its unique bonus features.

The first is the Wishing Well Bonus, which you can unlock by landing three wishing well symbols on the reels. You’ll then be presented with three wells to choose from, click or tap on one, and you’ll receive a multiplier of between 2x and 500x.

Land three leprechauns on the reels in the base game, and you’ll unlock the Road to Riches bonus feature, where you will travel along his golden path that’s lined with prizes. To move, the leprechaun will spin his wheel with seven possible outcomes. Land any of the numbers 1-6 and you’ll move along that corresponding number of spots on the path. But if you land on “Collect” this will lock in the prizes you’ve earned up until this point and end the bonus round.

Pots of Gold is the third bonus feature you can trigger in Rainbow Riches. This is unlocked by landing three pots of gold symbols on reels 2, 3, and 4 in the base game. This one is similar to the Wishing Well Bonus, presenting you with three pots to choose from with a multiplier of up to 500x up for grabs.
