Our Top Five Slots on Unibet Online Casino

As mentioned earlier, the collection of Unibet casino online slots is nearly 2,000 and counting. Thanks to the partnership with leading developers such as Pragmatic Play, Microgaming, and NetEnt, slots in Unibet casino are nothing short of amazing. Players can enjoy a variety of slot games including ageless hits as well as modern titles that come with innovative features which will blow your mind away.

Best Unibet slots

In the following section, we’ve handpicked games we believe are the best slots on Unibet casino online.

Book of Dead

Even 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.

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 wild and scatter. 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 prize of $100 per spin, it’s a pretty solid amount to win.

To do this, you’ll have to fill the screen with the book symbol. While this won’t happen that soon, Book of Dead is still a slot game that pays frequently. You’ll find it high among the list of featured Unibet slots regardless of whether you’re playing on desktop or via the online casino app.


Another massive Play’n GO hit, Reactoonz changed the online slots tune 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. 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 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 awake the great Gargantoon. It’s a 3×3 wild that can 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.

Big Bass Bonanza

Pragmatic 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.

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. This is a Norse mythology-themed slot game with plenty of surprises.

Money Train 2: RTP 96.4%

While 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.

Jammin’ Jars 2: RTP 95.35%

The 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.

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

Pirate Pays Megaways is one of the latest slots in Big Time Gaming’s Megaways portfolio. It may end up 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 merit. BTG knows how to create a great Megaways title, and Pirate Pays certainly qualifies as one.
