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.
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 if you’re playing on desktop or via the online casino app.
Reactoonz
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 2025 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.
