1. Avalon II
Avalon II is a Medieval-themed slot from the gaming giant in the slots category Microgaming. It has an engulfing theme and memorable symbols, but what it really stands out with are the 8 formidable bonus rounds. These can be triggered randomly, which builds up the thrill of the game, pumping the player’s adrenaline high. If you enjoy a good adrenaline rush, have a look at the best free slots games to play for fun.
All eight bonus features borrow themes from the legend of King Arthur. For example, during the Lake of Legend bonus, you’ll have the chance to re-forge Excalibur, thus building a payout of up to 15x your bet. If you like playing online slots games for free with bonus rounds, Avalon II should be at the top of your list.
2. Pink Panther
Put on your rose-coloured glasses and join the famous cartoon character in this Playtech game. The Pink Panther slot boasts 5 bonus games. These can be triggered randomly, which means you’ll have a hard time staying away from the fun theme and symbols and the opportunity of a free bonus round that might be waiting at the next spin. Speaking of that, this slot can be used in conjunction with some of the best latest casino bonuses.
You’ll have to make some important decisions. For instance, during the Pink Trail bonus, you’ll be able to follow in the footsteps of the legendary Inspector Clouseau, and you’ll have to choose whether to collect your winnings along the way or continue for a chance of a bigger reward. No matter what you decide, we’re certain you’ll have a lot of fun playing Pink Panther.
3. Twisted Sister
The Twisted Sister slot was inspired by the 1980s metal band with the same name. It is the work of Play’n GO, a game developer known to pay tribute to rock and metal bands. Despite the powerful rock theme, complete with the right sound effects and images, this slot has some entertaining bonus rounds. Triggered randomly, the Twisted Sister slot bonus rounds include the band features Scream, Go Wild, and Unite.
Rock fans will go wild for the We’re Not Gonna Take It feature, in which the Angry Dad Scatter overcharges the Angry Meter, thus raising the win multiplier by 1. Watch out for the Mega Band symbol, which also works towards amplifying your winnings. Give this Play’n GO online slot a try and see for yourself why Twisted Sister is one of our top online free slots with bonus feature. Check out also the best free casino online slots with no downloads.
4. King Kong Cash
The King Kong Cash slot from Blueprint Gaming offers a very friendly version of the famous fictional monster. Far from instilling fear, this gentle giant is cute and loveable and even voices the player’s disappointment when a spin doesn’t produce enough bonus symbols to trigger a bonus round. Speaking of bonus features, this slot game has 5.
You’ll be keeping your fingers crossed for the monkey napping by the reels to wake up because that’s when the bonus features are triggered. Each of the five bonus rounds has its advantages. For example, during Barrel Blast, King Kong throws golden barrels at the reels, replacing symbols to form winning combinations. The King Kong Cash bonus rounds are worth playing for, and the beautiful imagery makes the wait all the more pleasant.
5. Miss Fortune
Playtech’s Miss Fortune is no misfortune. In fact, it centres on a feisty good witch teaching magic – Miss Fortune. The magic theme is developed masterfully. There are all kinds of symbols that recall magic and sorcery. Even the spin button is placed over a black cauldron. Far from spooky or scary, the game has a cute and charming atmosphere.
There are a few bonus features to look forward to. Perhaps the most interesting one is the so-called Teacher’s Pet bonus round. This interactive feature is triggered by three bonus symbols landing on the reels. During the bonus game, you’ll have the chance to help Miss Fortune find her cute pet baby dragon that’s hiding in a locker. You’ll be awarded 10 picks. The more times you find the dragon pet, the higher your reward. Depending on this game’s availability, it can be played in conjunction with a top gambling bonus.
6. Jimi Hendrix
This NetEnt slot was launched in 2016, but it manages to bring the good vibes of the 1960s to the 21st century. Jimi Hendrix, who has inspired this game, needs no introduction. You’ll hear his easily recognisable voice and guitar throughout the game, while the symbols, such as the peace symbol, a flower, and a heart, call on the flower power generation.
The Jimi Hendrix slot has a number of excellent bonus games, including Purple Haze, Red Guitar Re-Spin, and Pick and Click. The last one is triggered by 3 Scatter symbols. The Pick and Click game consists of a coin win and three types of free spins – Crosstown Traffic, Purple Haze, and Little Wing. During the bonus round, players click on loudspeakers to reveal four types of symbols – three of the same symbol award the respective prize.
If you want to play free casino slots with bonus rounds, this player favourite from Play’n GO is a must-try. The Reactoonz video slot uses the typical for this game developer 7×7 grid, but that’s where anyone’s predictions end. Nothing could prepare you for the cuteness of the aliens that are anything but scary and the fun time this slot promises. That’s why we won’t even try.
We’ll focus on the awesome Reactoonz bonus features. The bonus round is called Quantum and is awarded randomly after winning on 25 symbols. It may trigger up to four Quantum features – Implosion, Incision, Demolition, and Alteration. But then, if the four features are followed by a fifth charging, you’ll get the bonus Gargantoon feature, during which you’ll see a 3×3 monster that serves as a Wild and substitutes all symbols.
8. Spiñata Grande
Are you looking for a free slot with lovely bonus features to play on your mobile? If the answer’s yes, Spiñata Grande is what you need. This NetEnt classic is favourite for many players, but does it have what it takes in terms of features? Also, can you play it for free? Indeed, this piñata-themed slot game has got it all.
Spiñata Grande will keep you entertained with beautiful graphics and cheerful audio, while keeping you excited for your upcoming wins. Launched in 2015, the game is just as exciting as it was in the beginning. It is a sight for sore eyes, a unique combination of colossal symbols, free spins, and a mini-slot feature. And all these come frequently enough. If you like being awarded free spins, here are the top free spins bonus offers.
9. Rainbow Riches
When the theme of Irish luck is mentioned, many fans of slots think of this particular game. But it’s not just one of the most popular Irish-themed slot machines. Rainbow Riches is also your go-to title when you want to play online slots games for free with bonus rounds. This Barcrest game has all the symbols you’d expect – a pot of gold, a rainbow, and an impish elf. Keep in mind that this game is often eligible for many of the best casino bonuses for Indian players as well.
Judging from the graphics and audio, Rainbow Riches might seem a bit dated, but that’s exactly what some players would appreciate. Moreover, it has 3 bonus features, so you have something to look forward to. The bonus rounds have appropriate names – Road to Riches, Wishing Well, and Pots of Gold. As soon as you trigger a bonus feature, you’ll forget whatever drawbacks the Rainbow Riches graphics might have.
10. Hot as Hades
We’ve got one last recommendation for fans of online free slots with bonus feature, so if you’d like to have more, check out our blog post about the top slots with bonus games. Hot as Hades is a Microgaming slot inspired by Greek mythology. And yes, Hades is the name of the Greek god of the dead and by association – hell. But don’t expect anything scary. The whole game setup is very positive and playful.
The Hot as Hades slot is a lovely game, but more importantly, it has some lovely features. There’s a Super Mode option that rewards you with free spins. However, we’re interested in the Quest for the Crystal Helm bonus round, which can be triggered by 3 crystal skull symbols on the reels. There are 5 levels, and you’ll have to make lots of choices that could potentially bring you big wins.
