Mr Null’s Wicked Wares by Pragmatic Play

Pragmatic Play delves into the occult with the Mr Null’s Wicked Wares slot.

The Game: Mr Null’s Wicked Wares is a horror-themed slot from Pragmatic Play with 576 ways to win, a 96.49% RTP, and a 5,000x max win. The gameplay focuses on Mystery symbols that reveal multipliers between 2x and 10x; when multiple symbols land, they multiply each other for larger payouts. The free spins feature adds progressive multipliers to the middle reels that increase whenever a Mystery symbol appears.

My Take: I think the occult bazaar theme is a welcome change from the usual slot visuals, but the high volatility means you’ll need to be patient through the quiet spells, and the multipliers kept me interested between bonuses. The spooky music and spin animations make this a fun slot, especially once the bonus features begin to kick in.

Where to Play: Ready to dabble with some occult spins? You can try Mr Null’s Wicked Wares at Casumo, along with all the latest Pragmatic Play slots.

Key Features of Mr Null’s Wicked Wares:

• Release Date: 04/05/2026
• Type: Video Slot
• Theme: Mystical, Supernatural
• Reels: 5
• Rows: 3 or 4
• Payout Rate: 96.49%

Idol Pop Fever by Pragmatic Play

Pragmatic Play has tapped into the K-Pop music craze with their latest slot.

The Game: Pragmatic Play is getting into the groove with Idol Pop Fever, a high-volatility slot played on a 5×5 grid with 20 paylines. Gameplay revolves around a Random Wilds feature where marked symbols transform into wilds with multipliers reaching 5x. Landing three VIP Ticket scatters awards 10 free spins, and when this bonus game feature is triggered, multiplier values can climb as high as 100x.

My Take: I’ve always been intrigued by the K-Pop phenomenon, and Idol Pop Fever captures that high-energy concert vibe well. Animated stadium visuals and the pumping soundtrack elevate gameplay, making each spin feel part of a live performance. I think this game becomes most satisfying when random wilds drop in time with the beat, adding a level of immersion many music slots lack.

Where to Play: Spin the musical vibes of this Idol Pop Fever slot at The Pools, where you can enjoy a large variety of titles developed by Pragmatic Play.

Key Features of Idol Pop Fever:

• Release Date: 02/04/2026
• Type: Video Slot
• Theme: Music, K-Pop
• Reels: 5
• Rows: 5
• Payout Rate: 96.50%
• Software Studio: Pragmatic Play

Huff N’ Puff CollectR by ELK Studios

ELK Studios expand on a winning formula with the Huff N’ Puff CollectR slot.

The Game: Huff N’ Puff CollectR is a 6×6 slot from ELK Studios (Light & Wonder) utilizing the CollectR mechanic. Four Pig symbols move around the grid to gather matching symbols and cash prizes rather than using traditional paylines. The grid can expand to 8×8, supported by a Wolf Crane that drops Wilds and a Golden Wheel triggering Bonus or Super Bonus rounds. It carries a 96.00% RTP and a 5,000x max win.

My Take: I believe that shifting to the CollectR gameplay is a bold move for the Huff N’ Puff series of slots. This time, our piggy protagonists feature in a base game that’s a lot more fun, especially with the symbol upgrades and expanding grid. Although this is a slot with high volatility, the constant interaction between the pigs and feature symbols keeps the game enticing, aided by the animations.

Where to Play: Find the new Huff N’ Puff CollectR slot available at 32Red, where you can aim to blow the house down while playing.

Key Features of Huff N’ Puff CollectR:

• Release Date: 23/04/2026
• Type: Video Slot
• Theme: Three Little Pigs, Construction
• Reels: 6 to 8
• Rows: 6 to 8
• Payout Rate: 96.00%
• Software Studio: ELK Studios
• Special Features: Symbol Collection, Collection Meter
• Volatility: High

Dynasty of Death by Hacksaw Gaming

Players battle for control of the Underworld in the Dynasty of Death slot.

The Game: Hacksaw Gaming’s Dynasty of Death is a 5×4 slot with 14 paylines and a 12,500x max win. It features the DuelReels mechanic, where expanding VS symbols trigger a battle between Hades and Persephone to award multipliers up to 100x and instant cash prizes. Three levels of free spins increase the frequency of these duels, with a top-tier bonus guaranteeing two VS symbols every spin. The RTP sits at 96.27% in this high-volatility game.

My Take: I’ve always liked the comic-book art style designs of Hacksaw Gaming, and I think it sets the tone well for this Dynasty of Death slot. The addition of cash prizes to the DuelReels engine is a positive upgrade, making sure that even if a multiplier doesn’t hit a win line, the VS symbol can still provide a payout. This helps to smooth out the high volatility and if you’ll excuse the obvious pun, makes any dead spins between bonus triggers feel less punishing for the player.

Where to Play: You can play Dynasty of Death at BetMGM, alongside a large choice of the latest Hacksaw Gaming slots.

Key Features of Dynasty of Death:

• Release Date: 30/04/2026
• Type: Video Slot
• Theme: Ancient Greece
• Reels: 5
• Rows: 4
• Payout Rate: 96.27%
• Software Studio: Hacksaw Gaming
• Special Features: DuelReels, Scatters, Multipliers
• Volatility: High

Prince of Purrwood by AvatarUX

Multipliers increase the win potential in the Prince of Purrwood slot.

The Game: Prince of Purrwood is a 6×3 cascading slot from AvatarUX, featuring an expanding grid and up to 10,000x max win potential. Using the MultiPop mechanic, winning symbols are replaced by multipliers that increase with every consecutive win in that position. Landing three or more scatters triggers the free spins, where the grid can grow to 6×6 and multipliers remain persistent throughout the round. The RTP is 96.13% in this high-volatility game.

My Take: Being a fan of cats, Prince of Purrwood immediately caught my eye. But while I do love the theme, the MultiPop system is also the main attraction, given that locking multipliers give the base game more purpose than a standard cascading slot. Because the grid and multipliers don’t reset during the bonus round, momentum builds quickly. This makes the top payout feel like a realistic target you can get your own claws into, rather than just a headline number.

Where to Play: You can join the feline forest heist in Prince of Purrwood at Videoslots, where you’ll also find a great selection of more slots developed by AvatarUX.

Key Features of Prince of Purrwood:

• Release Date: 16/04/2026
• Type: Video Slot
• Theme: Robin Hood, Cats
• Reels: 6
• Rows: 3 to 6
• Payout Rate: 96.13%
• Software Studio: AvatarUX
• Special Features: Cascades, Loaded Up, Reward Boosters
• Volatility: High

Final Words

Given that new slot releases have been coming thick and fast recently, narrowing down my list of top choices for May was far from easy. Pragmatic Play hit all the right notes with Idol Pop Fever, then went all spooky with Mr Null’s Wicked Wares, while Prince of Purrwood by AvatarUX stroked my affinity for cute cats. Hacksaw Gaming also introduced their new VS gameplay system with the Dynasty of Death slot.

But the final words for my favourite slot to try in May go to Huff N’ Puff CollectR by ELK Studios. Aside from the visual overhaul, adding CollectR gameplay mechanics with extra bonus features is certain to make this one a big hit at UK casino sites. I’m pleased to see the developer continuing to enhance such a popular slots series.
