Dorks of the Deep by Hacksaw Gaming
Dive with some of the biggest douchebags in the Seven Seas in Dorks of the Deep from Hacksaw Gaming. Trigger bubbly bonus games or expand reels for big treasure wins.
Hacksaw Gaming’s latest mid-volatility slot takes you to the deep blue sea. Dorks of the Deep will appeal to you if you love SpongeBob SquarePants or comedy-themed slots.
Expanding wild reels trigger when you land a treasure chest that would complete a winning combination. The wild reel reveals one of the game’s characters who each carry a fixed multiplier. The Ocean King pays the biggest multipliers in the game, worth up to 200x.
You activate the Deep Blue bonus game with three scatters in any position. The difference in this bonus is that the treasure chest always expands into a wild reel.
The bonus game offers a neat twist on the Hold & Spin feature. Wild reels expand as usual, but they remain sticky provided you keep hitting winning spins. You have 0–3 lives to use up, after which the sticky wild reel resets.
The bonus games increase in generosity the more scatters you trigger them with. You activate the Down Under bonus with five scatters, for example. There are always two wild reels, plus you can trigger additional spins throughout.
You can rely on Hacksaw Gaming to keep the innovations coming. With Dorks of the Deep, the developer has taken the wild reel and given it a 2025-style revamp. Try the game out for free and see what you think.
Serpentina by Massive Studios
Experience Serpentina from Massive Studios for a whole new take on Greek-myth-themed slots. Trigger cascades and watch bonus symbols drop onto the reels for added modifiers.
We’ve had plenty of Megaways slots in recent years that carry horizontal trackers for additional bonuses. Massive Studios’ Serpentina slot introduces two trackers for even more bonus fun.
You play Serpentina on a 7×7 grid and win by matching clusters of symbols. The game uses a cascading reels mechanic where winning clusters are removed from play. The symbols above drop into the new gaps created.
In addition, Serpentina may toss in global multipliers. These are applied to any winning cluster that appears on the reels. Random wilds can also appear, while low-paying symbols can transform into wilds anytime.
You trigger 8–20 free spins with 3–7 scatters anywhere in the game area. All wild modifiers are in play during free spins.
The horizontal tracker is what appeals in Serpentina. The tracker contains a random number of wilds and upgrades. When you hit a cluster, the symbols in the tracker will fall into the gaps directly below. An Upgrade symbol may also drop down, cloning a bonus as it drops onto the reels below.
As a casino content startup, Massive Studios is still growing its slots portfolio. The developer has over two dozen games out, including the innovative Hot Rocks.
Serpentina is the perfect showcase for Massive Studios’ big ambition. Give the game a spin for free today and see for yourself.
Wild Card Gang by Bgaming
Hit cluster wins with a difference in Wild Card Gang by Bgaming. Upgrade your winning clusters or hit up to 20 free spins in the main bonus feature.
The Wild Card Gang slot combines a crime theme with playing cards for one superb online slot. The graphics and gameplay are superb and you can view all your previous wins with a handy tracker.
Like Serpentina, Wild Card Gang uses a cluster wins mechanic to generate wins. You win cash by matching 4–12 symbols in horizontal and vertical clusters in the game area.
However, unlike regular cascading reels slots, clusters don’t completely disappear. Instead, some of the cluster symbols vanish while the rest are upgraded to the next-highest-paying symbol.
In addition, you can trigger up to 20 free spins by landing 4+ scatters. Cells containing winning clusters become marked. Any clusters hitting the same marked cells receive a 2x multiplier.
The multiplier keeps increasing if winning clusters keep appearing. It’s therefore possible to hit a maximum multiplier worth 128x. Naturally, you can also retrigger free spins by landing additional scatters during a free spin.
Last year, we reviewed plenty of new cluster win slots on this page. However, it’s good to see a developer thinking outside the box with cluster upgrades. Give Wild Card Gang a spin for free and see if the new modifier works for you.
Tumi Treasure by Seven ABC
Tumi Treasure is the latest game from a newcomer to our best new online slots of the week roundups. Trigger free spins and climb the trail to win more extra games.
We end our best new online slots of the week with another new developer: Seven ABC. Tumi Treasure is an Aztec-inspired slot that combines classic five-reel thrills with bonuses galore.
You play Tumi Treasure on a standard 5×3 reel set-up. Wilds substitute for regular symbols in the game. It’s the two bonus scatters, though, that up the ante somewhat as you play.
You trigger ten free spins with an escalating multiplier by landing three scatters on the reels. Plus, you may also bag additional spins by invoking the COLLECTOR.
You achieve this by landing a dragonfly and toad on the screen at the same time. The toad gladly gobbles up the dragonfly and adds it to the progress meter atop the reels.
You win ten additional free spins by completing four places on the meter. You can unlock more free spins by continuing to fill the meter.
In addition, you can trigger the Bonus Wheel with 3+ scatters anywhere. Spin the wheel one, two, or three times (depending on the number of triggering scatters) to win a cash prize.
Tumi Treasure has the appearance of a Tiki Treasures or Gonzo’s Quest. However, despite the shake of the symbols on every win, there are no cascades here.
The real fun in Tumi Treasure comes in the free spins bonus. The way you re-trigger free spins is a little convoluted, but it’s an exciting way to build up lots of extra free spins as you play.
