Interested in trying out the new slots we added during May? Here’s more on each one:

Robin in the Hood

Robin in the Hood is a recent release by Trigger Button and Relax Gaming with an RTP of 96.15% and high volatility. The theme features the timeless story of Robin Hood, everyone’s favourite hero, who also appears as one of the high-paying symbols. Some of the other symbols include a fair maiden, a warrior, a beer glass, a dummy, and the low-paying A, K, Q, J, and 10.

The gameplay unfolds on a 4×5 grid with Sherwood Forest in the background. You can make bets between £0.10 and £20. If your bets don’t trigger any bonus features, you can always purchase a batch of 7 free spins paired with some golden arrows or multipliers.

As for the bonus features, you can trigger the golden shot, which releases a multiplier and possible extra picks. The Fortune Wilds come with duplicate wilds and multipliers, while the Riches Spin releases random wilds that can duplicate. The most you can win, with or without the bonus features, is 5,540x your bet.

Joker Dreams

Joker Dreams is another interesting slot released in May 2025, but this time, the developer is Snowborn Games. This slot is now available in our game lobby, and playing it can mean you get a possible max win of 6,000x your bet. The RTP is 96% while volatility is high, and there are 20 preset paylines that can give you winning spins.

The most interesting part of the slot is the bonus features, each represented with its own symbols. So, don’t be surprised if you land a Wild, Free Spins, 1UP, Diamond, or Collect symbol – they all reward you with multipliers and batches of free spins. The standard symbols include a heart, club, spade, diamond, cherries, 7s, bells, and dice.

The bonus buy feature is also worth mentioning, as you can use it to purchase free spins for 50x your bet. Besides this, you can trigger four preset jackpots, Mini, Minor, Major, and Mega, which have preset values between £15 and £2,500.

Hot Slot 777: Hold the Jackpot

If you are a fan of retro-themed slots that feature gameplay similar to that of physical slot machines, this could be the perfect slot for you. Hot Slot 777 is a series of slot games developed by Wazdan. The series already includes a few other slots, with Hot Slot 777: Coins and Hot Slot 777: Cash Out being two of the titles available in our Unibet casino lobby.

We’ve added the provider’s latest release of this series to our lobby, Hot Slot 777: Hold the Jackpot. In this game, the main feature is the Hold the Jackpot bonus round, which awards you free spins and respins whenever you land more bonus symbols on the reels. There are other bonus features as well, including a bonus buy available below the grid.

The grid contains 5 reels and 10 preset paylines that you can preview in the game details. The symbols include 7s, watermelons, grapes, plums, oranges, lemons, and cherries. The RTP is 96.14%, while you can switch the volatility inside the game. If you’re lucky, you can win up to 1,500x your bet for bets between £0.20 and £1,000.

Reel Rush XXXtreme

Reel Rush XXXtreme is one of NetEnt’s new releases that features simple gameplay and interesting bonus features. When you start the game, you’ll notice the action happens on a 5×5 grid that is not fully unlocked. Opening all the reels will release 7 free spins with multipliers and sticky wilds.

Some of the other bonus features you should know are the two mystery symbols. The regular symbols award you a 1x multiplier, a wild, and a bomb. As for the golden mystery symbol, you can expect it to unlock a 10x multiplier, sticky wilds, and an expanding wild reel.

Even though it is relatively new, the slot already has an industry average RTP of 96.06%. The volatility is high, while the most you can win is 8,130x your bet. Betting starts at £0.30, but you can wager up to £600 in a single round. You can trigger up to 3,125 paylines, making it easier for you to make a winning spin.
