March‘s Hottest New Online Slot: Medusa’s Madness

The legendary Gorgon slithers onto the reels in Medusa’s Madness, a thrilling new online slot from Play’n Go. This fresh release plunges you into a mythological adventure packed with petrifying wilds, cascading wins, and epic bonus features.

Set against a haunting temple backdrop, the game uses a 5-reel, 5-row format with cluster pays. It offers serious payout potential with a 96.59% RTP and high volatility.

The game’s highlight is the Medusa Wilds, which expand across the reels, turning adjacent symbols into wilds. Cascading wins create chain reactions, boosting your chances of bigger payouts.

Trigger three or more scatter symbols to unlock the Free Spins round, where multipliers and sticky wilds amp up the action. With its eerie soundtrack and stunning visuals, this slot delivers an immersive experience.

Medusa’s Madness is a must-try if you enjoy high-volatility slots with dynamic features and a mythological twist.

Five More of the Best New Online Slots Reviewed

Let’s take a look at four more standout slots that have launched recently that we have playtested ourselves.

1. Big Bass: Return to the Races (Reel Kingdom)

The Fisherman’s back—sort of. This time, he’s swapped his fishing rod for a racecard, ditching the lake in favor of the track. Big Bass: Return to the Races is the latest entry in the ever-growing Big Bass series, and while the theme has changed, the core action is just as fun.

Developed by Reel Kingdom (part of Pragmatic Play), it keeps the same gameplay mechanics but throws in a fresh setting and a few new tricks. You’ll find it at some of the best online casinos, where new slot releases are always landing.

Wilds and money symbols are where the real wins happen. Just like in previous games, the Fisherman wild collects cash values from Money symbols whenever he lands. Free spins work the same way, but if you trigger the Golden Cup Free Spins, you’ll see even more Money symbols landing on the reels.

Want more action? There’s a bet boost option that ups your chances of landing the free spins round—handy if you don’t want to wait for luck to kick in. Between the bold new setting and familiar Big Bass mechanics, this one’s got a fresh feel without straying too far from what makes the series popular.

If you enjoy slots with bonus-packed gameplay, this one ticks the right boxes—especially with its free spins and cash collection mechanics, a staple of the best UK online casino bonuses.

2. Links of Flame (Slingshot Studios)

Once part of Microgaming, Slingshot Studios now operates under Games Global, releasing a steady stream of new slots in the UK. Their latest, Links of Flame, sticks to a familiar 5×4 reel setup with 40 paylines, but adds some interesting features.

The symbols? Classic fruit machine favourites—playing cards, cherries, bells, dice, Lucky 7s, and bars. Nothing too fancy, but that’s part of the charm.

There are four fixed jackpots up for grabs:

• Mini – £30
• Minor – £100
• Major – £1,00
• Grand – £10,000

What makes this one stand out? Power Stacks, which can load reels with matching symbols for bigger wins, and the Ultra Link & Win feature.

Land six or more coin symbols, and you’ll trigger a bonus round where you can pick up multipliers, extra rows, or cash-collecting booster coins to stack up your winnings. If you like straightforward gameplay with solid bonus mechanics, this one’s worth a spin.

3. Nugget Frenzy (Just For The Win)

It’s gold rush time! Nugget Frenzy is the latest slot from Just For The Win (JFTW), and it’s anything but ordinary. The reels? A wonky 3-4-5-6-7 setup that gives you a massive 2,520 paylines to hit those golden wins.

It’s a high-volatility slot, so don’t expect wins every other spin—but when they hit, they can be big. The max payout is 5,000x your stake, and with an RTP of 96.01%, it holds its own at the highest paying UK online casinos.

JFTW has been on a roll lately, and we think it’s one of their best online slots, rivalling the Adventures of Captain Black, Firebird Fortunes, and Dark Waters Power Combo.

Jackpots? Yep, but they’re fixed, not progressive. You’re looking at £75, £250, £1,000, and £5,000 for the top prizes, all tied to the Cash Collect and Free Spins features. Land three or more free spins symbols, and you’ll get six free spins.

As you play, sticks of dynamite start stacking up. When the round ends, they explode, revealing either Cash Collect multipliers or—if luck’s on your side—a jackpot symbol that drops a big payout. It’s a fast-paced, feature-packed slot with plenty of boom-or-bust potential.

4. Ryze (ELK Studios)

Some slots give away their theme in the title. Ryze isn’t one of them. ELK Studios has gone for mystery and intrigue with this one, and it kicks off with an intro sequence that teases the legend of Ryze—though it’s told in a made-up language, so good luck figuring it out.

What we do know? Ryze is a dragon-snake hybrid obsessed with gold. And if you like cluster pays slots, this one has plenty to offer. The 6-5-6-5-6-5 hexagonal grid makes for a unique layout, with clusters forming whenever five or more matching symbols touch.

Wins trigger a cascade feature, replacing winning symbols with new ones while multipliers build up with each drop. The max win is 10,000x your stake, and the RTP is lower-than-average at 94%.

This game’s got plenty of surprises. Fiery symbols? They make Ryze breathe fire across the reels, turning random symbols into matching ones for guaranteed wins. Key symbols? Drop them to the bottom of the grid, and you’ll trigger free spins, where multipliers don’t reset between spins. That’s where the biggest wins happen.

With bold visuals, a unique grid system, and a fiery bonus mechanic, Ryze is a slot that’s full of surprises. If you enjoy cascading wins, growing multipliers, and a bit of unpredictability, this one’s worth checking out.

5. Spirit Wolf Wins (Blueprint Gaming)

Blueprint Gaming has been around for years, making new slot games you’ll find both online and in brick-and-mortar casinos. Their latest game, Spirit Wolf Wins, brings a taste of the wild with a classic 5×3 layout, 50 paylines, and a max win of 2,500x your stake. The RTP sits at 95.04%, making it a medium-variance slot with a balance of steady wins and bigger payouts.

The symbols are split between low-paying playing cards and high-paying animals—wolves, cougars, bears, and eagles. But during bonus rounds, the low-value symbols vanish, making it easier to land bigger wins.

Trigger the bonus by landing three Dreamcatcher scatters, which award ten free spins. During these, all cash symbols hold a value, and landing four or more activates the Cash Feature. You’ll start with three respins, and every new cash symbol resets the count. Wilds can land too, helping to connect wins when you need them most. They don’t always show up, but when they do, they can make all the difference.

This slot leans on classic mechanics with a few twists, making it easy to get into. The mix of free spins, cash collection, and multipliers keeps the gameplay moving, and if you like slots with steady action, this one ticks the right boxes.

Their slots division, Reel Kingdom, continues to release hit titles that keep you coming back.

Play’n GO

Games Global (formerly Microgaming)

One of the industry’s oldest names, Microgaming started in 1994 and helped shape online casinos. In 2024, they rebranded as Apricot, selling their Quickfire platform and slot catalogue to Games Global. Their classic games, including their famous progressive jackpot slots like Mega Moolah and Major Millions, still feature at many casinos.

Yggdrasil

Despite the Norse-inspired name, Yggdrasil is based in Malta. They may not make a big splash when the release new slots games, but their consistent quality has earned them a strong reputation. Their Vikings series, which keeps getting angrier and more intense, remains a fan favourite.

Red Tiger

Few developers have risen as fast as Red Tiger. Founded in 2014, they quickly built a reputation with cutting-edge slots like Primate King and Case Closed. Their rapid success led to a 2019 acquisition by NetEnt, followed by their move into the Evolution Group in 2020.
