Aussies VS Emus by Blue Guru

We start our look at the best new online slots of the week with another fair dinkum release from Blue Guru. Aussies VS Emus is an Outback adventure where a hunter and emu may clash to create some explosive wins.

Blue Guru has only been on the casino scene since 2021. However, in its brief lifetime, the developer has been making full use of its favorite themes of peace, Eastern mysticism, and philosophy.

There’s not much in the way of peace and love in Aussies VS Emus. However, the lush Outback theme should appeal to Blue Guru’s customers in Australia, where the company supplies some of its games.

You may remember we focussed recently on great cluster wins slots hitting the market. Aussies VS Emus has a similar mechanic where winning clusters are removed and replaced by symbols appearing above.

In addition, any Dynamite Mystery Boxes that appear adjacent to the winning clusters explode to reveal mystery symbols in their wake. You also trigger eight free spins if you explode three or more Dynamite Mystery Boxes.

Look out for the wild emu on the reels. You trigger the Emu Charge Feature if a bird appears with a wild. The emu sprints off toward the wild, leaving a mystery wheat path in its wake. The wheat may reveal winning cash sums.

You can also trigger instant prize coins when you land an Emu and Golden Aussie Wild together. Cash prizes range from 1x to 250x stake. You may also hit multipliers that apply to the instant prize coins.

Aussies VS Emus is a cheeky little slot with the potential for bonuses. The Aussie Wild and Emu symbols hit frequently to leave a trail of wheat behind. That means more bonus moolah for you! Give the game a spin for free today.

Ragna’s Rock by Gameart

Prepare for the Norse end of days with Ragna’s Rock by Gameart. Trigger random wilds and super-sized symbols, or unlock the Rock Box for big modifiers and multipliers!

Like Aussies VS Emus, Ragna’s Rock uses a cluster wins mechanic. However, there are also symbols that increase in size every time you fill the meter.

Let’s start with the game area. You play Ragna’s Rock on a 7×7 grid in the classic style of so many cluster wins slots. The authentic music is a delight, as are the stone sound effects when one of the rune tablets drops down the reels.

Super-sized symbols are among the best features of Ragna’s Rock. When hitting four matching symbols in adjacent positions, they transform into a single super-sized symbol. You also earn double if one or more super-sized symbols are in play at the same time.

You fill the ‘Rock Box’ with every consecutive win. Complete the section and you’ll unlock a new feature bonus. The purple EXPLOSION transforms 1–8 symbols into wild symbols, while adjacent symbols are also removed. The ‘SLICE AND DICE’ feature places a wild symbol in the center of the reels and creates two diagonal lines with an identical symbol.

Once fully charged, you trigger the Rock Box’s WILD BERSERKER BONUS. A 3×3 wild Ragna symbol is added to the game area. It breaks into 2×2 wilds if it doesn’t contribute to a win, then again into 1×1 wilds.

And don’t forget the win multipliers for unlocking each feature. You can trigger a multiplier worth up to 10x if you unlock enough sections on the Rock Box.

With bonuses galore and random wilds on any non-winning spin, there’s plenty to recommend in Ragna’s Rock. Give the free slot a spin for free today.

Animafia by Peter and Sons

We join the wild wise guys in the forest next with Animafia from Peter and Sons. This is a Mob-themed slot with a difference where three different types of wilds can appear at any time!

Not only is Peter and Sons the best-named slots developer in the business, but it’s also the purveyor of some awesome casino games.

Animafia is the latest release from the brains behind Book of Books and Abrakadabra. The reels are arranged in a 5×5 set-up with stacked symbols to improve your chances of a big win.

The game features three types of wilds: random wilds that appear at any time, expanding wilds, and monster wilds. 4–15 random wilds will be added while expanding wilds cover the whole of one of the reels 1–5.

The monster wild may measure 1×1 to 5×5. You can also grow the size of your monster wilds by collecting gold scatters.

Those golden lock scatters increase your free spins meter. The meter starts at six, with a maximum of 20 available. The bonus feature begins once you collect three scatters. Look out for roaming wilds too which can grow to become roaming monster wilds.

There’s a lot of volatility in Animafia. You’re hoping for stacked symbols and wild modifiers to create the really big wins. There’s certainly a lot for free spins fans if you hold on long enough to progress the meter along. Why not give the game a try for free today and see what you think?

Hellapenos by Thunderkick

Things are hotting up with our final game: Thunderkick’s Hellapenos. Trigger multiplier wilds and expanding Devil symbols in one of Thunderkick’s spiciest slots of the year.  

Hellapenos is Thunderkick’s spiciest slot release for some time. The RTP of 96.19% ensures a nice amount of gameplay. Plus, you can land multiplier wilds to increase your payouts.

The game uses a staggered reels model where the five reels are set out in a 3-3-4-4-4 arrangement. There are 100 paylines in the game in total, all running left to right.

You can land lots of wild symbols to improve your overall payouts too. Multiplier wilds are valued at 2x and appear on any reel. They substitute for all symbols other than the scatters and expanding devils. It’s possible, however, to have up to three wild multipliers for a total of 8x on your win.

Though the left-most reels only have three rows each, symbols may appear in stacks. Fill the entire left-hand reels with identical symbols and you active 1–3 multiplier wilds on the other three reels. That guarantees payouts across multiple paylines.

The expanding devil symbol may appear anywhere on reels 3–5. He expands only when completing a winning combination. Otherwise, he appears as a wild symbol only. The Devil can also expand through multiplier wilds, turning into a paying multiplier himself.

We nearly forgot about the free spins bonus. You trigger seven free spins by hitting three scatters in any position on reels 3–5. Any Devil landing on reels 3–5 activates that reel for the rest of the feature.

Turn the heat up with Hellapenos today. We have a freeplay version just for you right here.
