#1 Book of Dead (Play’n GO)

book of dead slot playn goEven though it was released back in 2016, Book of Dead remains a huge name in the slots industry. Developed and released by Play’n GO, it’s an absolute classic and a mainstay in top-10 slot lists. It’s one of the most popular slots at Unibet casino online as well. Book of Dead revitalized the age-old Book of… genre, spawning numerous sequels and spin-offs that are successful as well. First popularized by Book of Ra Deluxe (Novomatic). PLay’n GO retained superb gameplay but injected this machine with a well-needed visual boost in terms of slick graphics and superior animations.

The slot is a classic Egyptian mystery tale that takes place in a pyramid. All the action revolves around the mysterious Book of Dead, which plays the role of the wild and scatter symbols. Play’n GO’s slot RTP for this game is 96.21% which is right around the average for highly volatile slot games. With a bit of luck, you can win 5,000x your stake across the 10 paylines. That may not sound like much, but considering the max bet is $100 per spin, it’s a pretty solid amount to win.

To do this, you’ll have to fill the screen with the Explorer symbol during the free spins round, where it will expand to cover the entire reel. While this won’t happen often, Book of Dead is still a slot game that pays frequently regardless of the bonus symbol. You’ll find it high among the list of featured Unibet slots regardless of whether you’re playing on a desktop computer or via the mobile casino app.

If this kind of gameplay appeals then search through the Unibet slots lobby for other game titles that mention “Book” and you will find lots of great slots that are similar in playstyle to this superb one.

#2 Reactoonz (Play’n GO)

reactoonz slot playn goAnother massive Play’n GO hit, Reactoonz, changed the online slot landscape when it hit the market in 2017. It’s a slot that uses the Cluster Pays engine in a smart way tailored to the slot’s theme. To win, you’ll need a cluster of 5 or more of the same alien species. When wins are created, these help to fill up the power meter; special features are then played court after the winning combinations cease. It’s one of the highest RTP slots in Unibet’s library at 96.51% and also one of the most thrilling rides you can enjoy.

What makes Reactoonz so great are the special features you can land on each spin. For example, every win triggers further reactions that can go on and on for continued wins. In this way, you can land plenty of winning symbols and combinations that will fill a special meter and finally awaken the great Gargantoon. It’s a 3×3 special wild that can subsequently split into 2×2 and 1×1 symbols and occupy large portions of the grid and significantly boost your payouts.

It’s a highly volatile slot with great features that can deliver wins over 4,500x your stake. If you’re looking at top slots at Unibet casino, Reactoonz certainly qualifies.

This grid-based style of slot has become very popular with slot players; Play’n GO is possibly the master of this genre, but make sure to check out games from Pragmatic Play and Push Gaming which also has superb grid based slots on offer.

#3 Big Bass Bonanza (Pragmatic Play)

big bass bonanza slot pragmatic playPragmatic Play’s Big Bass Bonanza arrived quietly on the iGaming market in 2020 and became a sleeper hit. It’s a fishing-themed slot game with plenty of massive fish in the pond, and maximum line wins of 2,100x your bet. The medium-high variance slot game has an RTP that ranges between 95.67% and 96.71%. The action takes place on a 5×3 grid with 10 active paylines.

Trying to find your luck with a fishing rod in a big pond is not that easy. However, you can catch the big fish in Big Bass Bonanza, especially thanks to re-triggers and multipliers. All the wilds you land in the base game are collected in a special meter. They trigger the progressive multiplier and activate the free spins, where the action really picks up.

With a bit of luck and x10 multipliers, the biggest bass in this sea is worth 2,100x your stake. Big Bass Bonanza is a pretty fun slot from Pragmatic’s kitchen and one of our favorite Unibet casino online slots. Fans of this slot will find that there are at least 5 other “Big Bass” slot variants on offer by Pragmatic Play, as well as numerous other fishing-themed slots from other developers.

#4 Thunderstruck II (Microgaming)

thunderstruck 2 slotMicrogaming’s Thunderstruck II may have been released over a decade ago, but it’s still one of the most popular slots at Unibet casino online. It’s a sequel to the hit Thunderstruck slot from 2004, improving upon every aspect of its predecessor. Thunderstruck II is bigger and bolder than the original, with a higher number of ways to win, better RTP, and bigger and better prizes.

Ride the lightning, and you can win stunning sums of cash over 8,000x your stake thanks to the Wildstrom feature turning up to all 5 reel wild. This is a Norse mythology-themed slot game with plenty of surprises. The main one is the Great Hall of Spins feature, where you can hit the biggest wins. The great hall of spins is an unlockable sequence of 4 unique free spins bonus round; on playing this slot for the first time, you must trigger the free spins round several times before unlocking the slot’s true winning potential. Valkyrie, Loki, Odin, and Thor all await, our favorite round is Loki due to the unpredictable wild feature and overall volatility, but players are sure to find their own personal favorite round after playing this machine.

With high variance and a slot RTP of 96.65%, Thunderstruck II is a Microgaming hit you simply must try. With 243 ways to win and electrifying features, you’ll love the trip to Asgard and beyond in one of the best slots on Unibet casino online. Fans of this machine should check out the legendary Immortal Romance slot, which offers similar gameplay and bonus features but with a dark vampire theme!

#5 Jammin’ Jars (Push Gaming)

jammin jars slot push gamingDeveloped by Push Gaming and released in 2018, Jammin’ Jars became a massive hit with slot fans as soon as it was released. Its jamming soundtrack and the neon visuals make it a graphical delight, and the technical stats are pretty solid too. The slot’s RTP ranges between 95.25% and 96.83%, and the maximum win on the Cluster Pays grid can hit a whopping 20,000x your stake.

The multiplier wilds that are multiplicative when combined in wins is the slot’s ace in the sleeve and the biggest reason why it’s among the top-rated Unibet casino online slots. Jammin’ Jars is a truly modern online slot with fun and simple gameplay that will appeal to slot fans from all walks of life. As a Cluster Pays slot, it relies on major block symbols that can deliver bigger wins. It also features avalanche wins and multiplier wilds in the free spins round that can bring the big bucks.

It’s a colorful slot with a great soundtrack that will get you in the groove. With maximum line wins worth 20,000x in the bag, Jammin’ Jars is one of the jamming Unibet slots you simply must try.

Although Jammin Jars already has a sequel, the original still remains the most popular of the two, with its simple but effective gameplay and huge hit potential.

Why spin high-paying slots? Well, the answer is easy – because they pay big. The best slots at Unibet online casino can shell out wins worth several thousand times your stakes.

  2. Money Train 2 (NoLimit City)
  3. Jammin Jars 2 (Push Gaming)
  4. Pirate Pays Megaways (Big Time Gaming)
  5. Piggy Riches Megaways (Red Tiger)

300 Shields Extreme: RTP 95.299%

300 shileds extreme nextgen gaming300 Shields Extreme is a super high-variance online slot from Nextgen Gaming; with a few minor tweaks to the original 300 Shields slot, this machine is about as volatile as you get. With 300x Multiplier wilds on offer during the stage-based free spins round, this slot does a superb job of building anticipation as you collect the thudding shield scatter symbols to progress through the bonus round.

Reaching the final stage awards you with 5 free spins with 300x multiplier wilds, and from here, it’s a case of just landing one decent win with this multiplier to walk away with a huge win.

Add in the ability to bypass the base game with a bonus buy feature, and you can replay this edge-of-the-seat bonus round at will.

While many have tried to emulate this kind of machine, it is Nextgen Gaming that seems to be the master, with Rise of the Mountain King being the closest rival slot.

Money Train 2: RTP 96.4%

money train 2 slot relax gamingWhile Relax Gaming is not a provider in the same vein as Microgaming or NetEnt, the studio definitely made waves in the iGaming community with the release of Money Train in 2019. It was a wild west slot with more than a few twists and a pretty high max. win of 20,000x your bet. Considering the popularity of the original release, it was clear that Relax will go for a sequel or two. The first one came out in mid-2020, improving upon every aspect of the original.

Money Train 2 is a bigger and bolder train heist. The slot’s action plays out on a 5×4 grid with respins and several bonuses. The RTP has been bumped up to 96.4%, and the maximum win has been bumped up to 50,000x as well. Money Train 2 has 40 paylines, just like the original, but with more special features that spice the gameplay up.

A further sequel has already been released earlier in 2022. Relax Gaming’s Money Train 2 put the studio on the list of up-and-comers that are worth counting on. If you’re looking for a wild west slot with a twist, it doesn’t get any more twisted than this.

If high variance volatility games appeal, then literally all of Relax Gaming’s releases should be investigated as they are a superb developer well aware of player trends tailoring their releases to cater to current trends, sticky wilds, multipliers, and engaging bonus features.

Jammin’ Jars 2: RTP 95.35%

jammin jars 2 slot push gamingThe success of Jammin’ Jars drove Push Gaming to think about a sequel. Jammin’ Jars 2 was released in the summer of 2021 and uses the Cluster Pays engine instead of regular cluster wins. The RTP has been raised to 95.35% in the base game, although it ranges depending on the situation on the reels. What’s even more impressive is that Push Gaming has also raised the max. line wins – this time, you can win up to 50,000x your stake.

Jammin’ Jars 2 is a groovier and more colorful slot game than the original. The action takes place across an 8×8 grid where clusters of symbols can deliver massive rewards. All of the action is aimed at the fantastic Giga Spins bonus feature where all the Giga wins lie.

The slot is a great continuation of the action in Jammin’ Jars; this time visually improved for 2021. It’s a pretty fun and thrilling ride and surely one of the best slots to play in the Unibet casino.

Pirate Pays Megaways: RTP 96.23%

pirate pays megaways slot big time gamingPirate Pays Megaways is one of the latest slots in Big Time Gaming’s Megaways portfolio. It may be one of the best too, considering the 96.32% RTP and the maximum wins worth an incredible 104,400x your stake.

The name of the slot is a dead giveaway of the theme. This is a pirate-themed slot with plenty of booty to claim for the luckiest players. The fact that it’s developed by Big Time Gaming, the original Megaways inventor, gives it a lot of merits. BTG knows how to create a great Megaways title, and Pirate Pays certainly qualifies as one.

It’s one of the top games in the Unibet slots app that you’ll find in the featured slots row. Thanks to the fantastic winning potential, this is a pirate crew you’d love to join.

Fans of Megaways slots are spoiled for choice; there are literally hundreds to choose from, but seek out the Big Time Gaming ranges first, as these are the original pioneers and masters of this genre of slots.

Tips to Play Unibet slots

Slots are a game of luck, so if you choose to play them for cash, it’s best to start small. The slots Unibet casino offers can also be played for fun. If you want to see how a new game works, it’s best to try it for free first before you splash the cash.

You can spend your bankroll on slot games pretty fast, so it would be wise to set a limit on it. Limit your spending on a daily or weekly basis, and you should be fine. Whenever you reach your limit, log out and come back another day. No need to chase your losses – that’ll put you in trouble before you know it.

Low-volatility slots pay more often, so they’re a much safer option than high-variance slot games. The latter is much riskier for beginners, so if you’re only starting in Unibet casino, have this in mind and always adjust your bet size accordingly to how volatile a machine is.

Playing slots on Unibet

If you’re attracted by the lucrative rewards, then Progressive Jackpots offer life-changing wins; keep in mind that a jackpot strikes rarely. You could say that your chances are one in several million. While there’s still a possibility to hit a jackpot on a single spin, they would be slim at the very least.

Unibet Slots RTP

The Unibet casino RTP is not publicly displayed. However, being one of the leaders in iGaming, Unibet pays handsomely in return for your bets. The good news is that all slots at Unibet casino display the return to player percentage. You can check it under the game’s guide before you start spinning.

Some of the slots with an RTP of 98 % or higher on Unibet are:

  • Rainbow Riches Pick 98 %
  • Mighty Black Knight 98 %
  • 1429 Uncharted Seas 98.5 %
  • Joker Strike 98.11 %
  • Bloodsuckers 98 %
  • Jokerizer 98 %
  • Dr. Jekyll Goes Wild 98 %
  • Jokerizer 98 %

Keep in mind these are the theoretical value obtained from testing the games over millions or billions of spins, but use the values as a good gauge to know how tight or loose they are in the long term regardless of volatility.

Understanding Paylines

When playing online slots, you have first to understand what paylines are. In the simplest terms, these are horizontal, vertical, or diagonal lines that symbols land on. When a specific combination of matching symbols or wilds lands on these paylines, you get a payout.

Old-school slots originally had a single or just a few paylines. Modern video slots have thousands of ways to win, significantly increasing your winning chances.

Take a few minutes to check through the game rules, as each developer will have their own style of paylines, so you can familiarize yourself with which reels you should be looking out for the wins.

How Unibet Casino Keeps Play Fair

As mentioned earlier, Unibet casino has all the licenses it needs to operate legally in New Jersey and Pennsylvania. Its games are tested by leading testing labs and powered by the biggest software providers, so you don’t need to worry about the legal side of things or the fairness of the games. They are also widely regarded by players in Europe and are a supremely well-established casino in this region.
