Free Video Slots with Bonus Rounds by Category

There are hundreds of potential free online slots with bonus rounds no downloads games that you can try on the Internet. Of course, choosing from a such a large pool of titles can be a difficult process. We have streamlined it a bit for you, having listed the top free slots by category. See our picks directly below.

Best Free Slots Casino Games with Bonus Rounds

1. Avalon II: Quest for the Grail

When it comes to free online bonus rounds no downloads games, Avalon II: Quest for the Grail by Microgaming is one of the all-time favourites. This game shows us the journey of King Arthur to recover the Holy Grail, scoring numerous winning symbols in the process. It has all the features expected from a modern video slot – 243 ways to win, free spins, scatters, and wild symbols.

However, this video slot really stands out from the pack with its massive bonus round sequence. Rather than the traditional bonus game, which is rehashed over and over again, Avalon II lets us join Arthur on his quest. We get to travel through numerous mysterious and magical locations, serving as individual mini-games. Each round offers a specific niche, including free spins, trailing wilds, cash prizes, pick and click, and more. It is evident that software provider Microgaming pulled out all the spots while making this game, and we definitely appreciate it.

2. Warlords – Crystals of Power

Of course, industry leader NetEnt is not far behind with its offerings of free video slots with bonus rounds. No downloads are necessary to play Warlords – Crystals of Power. As you can glimpse from the title of this slot, it deals with a set of tough warriors and their battles. You will find no lack of action while playing this game. The standard 5-reel setup is covered by 30 paylines, while our favourite free spins also make an appearance – three different types, in fact.

Warlords – Crystals of Power also goes hard where it concerns its bonus features. Triggering the bonus round will see a face-off between two of the warlords, with one gaining the upper hand. Following this, you will earn rewards in the form of free spins.

3. Blood Suckers II

Another NetEnt entry on this list, Blood Suckers 2, seemingly took the world by storm when it was first released. Years later, it is still prominently featured at the best slots sites in the UK, and for a good reason. This is some of NetEnt’s best work of all time. Vampire themes are not that common with modern video slots, but the developer has created not only a killer aesthetic but also one of the top slot games of the 2010s.

Of course, Blood Suckers II would not make our list if it didn’t rank among the top online free slots with bonus games. The bonus round of this title is triggered when you spin three or more bonus symbols at once. The more symbols you get, the higher your rewards will be. As for the mini-game itself, it has five different levels, and you get to search caskets and treasure chests to find rewards.

4. Elements

From the confines of old crypts and burial sites, we move on to outer space. Elements by NetEnt has been around since 2013 and has stayed relevant despite the slew of other more modern releases. There is a definite charm to this game, and we think that you will not want to miss out on it. The graphics are beautiful to look at, while the gameplay is absolutely first-class.

Of course, the reason why we’re here is to see if this title deserves a spot among the top free video slots with bonus rounds; no downloads are required. The Free Falls game mode will shower you with rewards, adding additional wild symbols to the reels. All in all, the bonus feature is a little understated and not as glorious as those of other games, but it is definitely worth your time.

5. Dead or Alive 2

Dead or Alive 2 is one of those games that you do not want to miss out on. Another hit by NetEnt, Dead or Alive 2 brings into the world of the Wild West in all its glory. Gameplaywise, this title is quite simple to get around – 5 reels with 9 paylines spread out across them. You also benefit from the usual special symbols and free spins.

Still, Dead or Alive 2 also brings to the table intriguing and compelling bonus rounds. These take the form of free spins but with some additional features. Specifically, you can receive winnings from multipliers, extra wilds, sticky wilds, additional spins, and more. Despite being simplistic when compared to other bonus games, this round can definitely be rewarding.

6. Mega Joker

Mega Joker by NetEnt is quite unique and compelling when compared to other video slots. In fact, this game can be better classified as a classic slot since it features the old-school 3-reel setup. However, it goes beyond the simplistic gameplay of classic games by introducing the supermeter feature.

Basically, this is a second set of reels, which you can activate after a winning spin on the standard reels. Here, the bet limits will be set higher than normal, but the rewards will be exponentially greater. You will get to spin the supermeter for as long you can score winning combinations.

Another great aspect of the supermeter is that it offers RTP values of 99%. This level of return is frankly unheard of when it comes to slot games. This makes Mega Joker deserving of a spot among the the best payout slots in the UK and a must-play for any avid fan of online slots.

7. Pink Panther

We cannot have a proper list of great free slots casino games with bonus rounds without a Playtech entry. Pink Panther is the perfect title to represent this development behemoth. Released in the distant 2010, this slot still ranks as one of the best slots on the Internet. Fans of the old-school cartoons will appreciate this faithful adaptation to the slots format that maintains the atmosphere and entertainment value of the franchise.

The Pink Panther slot game is somewhat unique in the sense that it offers five different bonus mini-games, not unlike Avalon II. These include pick-and-click sections, a prize wheel, free spins, cash rewards, and more. While the game may not look like much based on today’s standards, Pink Panther is jam-packed with great features, and we are certain that you will enjoy it as much as we have.

8. Pink Elephants 2

Pink Elephants 2 is one of the newest titles on this list, brought to us by software developer Thunderkick. It instantly stands out with its innovative graphics style and lighthearted theme. Presentation is a major strong point of this slot, but the gameplay is not to be ignored either. Pink Elephants 2 is one of the rare 6-reel slots and uses the 4096 ways to win system. All around, this is a great game to play for free or for real money.

As far as the bonus round is concerned, you need at least 1 Mystery scatter symbol on the reels, though the game is triggered randomly. Effectively, you will win a round of free spins, during which you will collect Elephant Orbs in the meter to the left. Completely filling up the meter will replace all animal symbols with Pink Elephants for the remainder of the round. The Elephant symbols provide the best payouts, which could lead to massive wins.

9. Narcos

We all know of the excellent Netflix TV series, but did you know there is a slot game dedicated to it, as well? Indeed, the Narcos slot game easily earns a spot among the top free online slots with bonus rounds. No downloads games are easy to come across, but few are as exciting and entertaining as Narcos.

Five reels and the 243 ways to win system instantly make this game compelling. Of course, we are after the worthwhile bonus rounds, a key feature of the Narcos slot. To make a long story short, the bonus round begins with a number of free spins. During that, only Locked Up and Golden Locked Up symbols will spin on the reels. You can easily score wins using just the two symbol types. A winning combination of Golden Locked Up symbols will unlock either multipliers, upgraded symbol values, or a cash prize.

10. Guns ‘N Roses

The last entry on our list comes in the form of the Guns N’ Roses slot, one of the popular NetEnt music slot games. It is readily available at many different UK casino sites and easily one of the top free online slots with bonus rounds. No download games are quite easy to get ahold of, making Guns ‘N Roses accessible to a wide range of players.

Of course, our main interest in this game comes from its bonus round, or rather three bonus mini-games. Whenever you spin three bonus symbols, you will be granted one of three rounds. These rounds will provide you with a pick-and-click section, free spins, and cash prizes. You don’t pick the specific mini-games; rather, they are assigned to you randomly.
