For our best new online slots of the week, we are traveling back in time. Pragmatic Play and Spinomenal revisit the nostalgic slots of old Vegas, while Nucleus Gaming take us on a trip to an era of Vikings and Norse myth. Finally, Kalamba Games take us into a world of horror with Zombie Queen.

First up are Pragmatic Play with their classic slot, Firestrike. It’s big on volatility, wilds, and jackpots. Could this be the game to give Bally a run of their money?

Spinomenal also celebrate classic Vegas slots with their new Colossus Fruits slot. The game features giant symbols that can improve your win as you spin. Also going super-size are Nucleus Gaming, whose Norse-themed Runes of Odin has cascading reels and a ton of bonus fun.

Upping the reel stakes are Kalamba Games. Their horror-themed six-reeler, Zombie Queen, has free spins, a progressive multiplier, and a HyperBonus which lets you cut straight to the bonus rounds. Let’s explore these exciting slots a little closer.

Firestrike | Pragmatic Play

Our first classic slot release of the week is Firestrike by Pragmatic Play. This new slot recalls your favorite Vegas AWP machines from Bally or IGT and really ramps up the wild action.

Firestrike is played on a 3×5 reel setup, and there are 10 paylines to aim for. This is an online slot that is high on volatility and not for the faint-hearted. But can you keep striking until you hit the Firestrike wilds and the Grand Jackpot?

Pragmatic Play might only have been around since 2015, but they have already released a rich and diverse range of slots games.

Classic slots make up a surprisingly large part of the Pragmatic Play output. Games like Extra Fruity and Extra Juicy were designed for online bingo players in mind, but they have gained a wider following.

Firestrike is the latest nostalgic slot to join those fruity titles. It’s a regular 5-reel slot, and it’s definitely high on the volatility scale. While the regular jackpots go up to 100x your bet, the big payouts are reserved for the Firestrike symbols.

Hit six or more Firestrike icons anywhere and you will win corresponding bonus amounts. Landing six Firestrike symbols will pay 1x your bet, while 15 will award you 5,000x. You will also win the fixed jackpot by hitting 15 Firestrikes.

In addition to Firestrike jackpots, there are also plenty of Firestrike wild symbols, many of which can appear stacked on the screen.

Firestrike is the game for you if you love stacked wild mayhem. Give it a test drive at VegasSlotsOnline now.

Runes of Odin | Nucleus Gaming

Like BetSoft, Nucleus Gaming made a name for themselves in the world of 3D slots. Titles like Coco Bongo, FireCrackers, and High Noon all feature immersive animation and graphics, plus some kick-ass bonus features to boot.

The Runes of Odin slot is Nucleus Gaming’s attempt to tap into the everlasting craze for Norse-themed slots. It’s packed with bonuses and features, and a lot of action across its seven reels.

Runes of Odin is the slot for you if you love Colossal Reels games like WMS’s Queen of the Wild II. It’s played over seven reels and seven rows to create hundreds of potential ‘clusters’.

A winning cluster contains four or more matching symbols. Winning symbols will then explode, allowing the symbols above to fall into their place. Clusters can pay up to 9x your bet if you match eight red lava symbols.

This is a cascading reels slot with a difference. There are various Forces of Nature bonuses to look out for. The Rushing Water removes two rows or columns for added cascades. The Torrent of Waves floods two columns and rows, while The Fire Within burns away a small cluster of symbols to create a winner. Look out for The Earthquake, which will destroy all symbols of the same type on the reels.

We particularly liked Odin’s Mighty Spear. When Gungnir appears, the Spear Trail is filled in. Complete the trail and you will trigger 10 free spins.

Runes of Odin is a new slot that makes great use of the cascading reels feature. Head for Valhalla and test the game out for free today.

Colossus Fruits | Spinomenal

Spinomenal have only been around for five years, but they’ve already built up an impressive range of online slots. While their best games are Egyptian-themed slots like Book of Guardians and Egyptian Rebirth, they also have a few classic slots in their arsenal.

Colossus Fruits follows heavy-hitting classics from Spinomenal, such as Surprising 7. The game follows a 3-4-4-4-3 reel setup and features 30 paylines. Classic slot symbols like melons, cherries, and grapes fight for space across the five reels.

But it’s the giant symbols that set this game apart. As in games like IGT’s Golden Goddess, there is a colossus fruit icon that will cover nine reel spots at once. There are also stacked symbols that can link up with other reels for big wins.  

Colossus Fruits has a free spins feature which can be triggered by landing one Free Spins symbol on reel 1 and one on reel 5. You win 10 spins automatically. Look out for the prize box feature too. With every free spin, the box will reward you with a win multiplier or an extra free spin.

But there’s more: you can opt to buy the feature and trigger 10 free spins automatically. Use the Choose Your Bet function to modify your bet. The buy price increases as you raise your chosen free spins stake.

We love classic slots at VegasSlotsOnline, and Colossus Fruits offers players a little more control over their stakes. It reminded us of Barcrest’s Big Bet games, which put you totally in the driving seat when it comes to your slot spins. Check it out for free at VegasSlotsOnline and see what you think.

Zombie Queen | Kalamba Games

It’s not quite Halloween yet, but no one seems to have told Kalamba Games that. The new Polish developers have already thrilled with high-quality slot releases like Machina Megaways and Dino Odyssey.

Now, they’re taking on the horror theme with Zombie Queen. It’s an atmospheric online slot played with 50 paylines across six reels. Symbols can appear stacked, and there is a base game jackpot worth 1x your total stake for hitting six of a kind.

But Zombie Queen isn’t about base game payouts. This slot is all about the bonuses.

Like Spinomenal’s release this week, Zombie Queen lets you buy straight into your preferred bonus. For a set amount, you buy 8 free spins with 3x wilds, 7 spins with 2x wilds, or 5 free spins with 1x wilds. Alternatively, you can try and trigger the feature normally via the base game.

To trigger the free games, land three more bonus skulls anywhere. During the feature, the zombie queen will appear as a sticky wild multiplier that locks in place. Spooky eyeballs can appear to award an extra free spin.

Elsewhere in the game, there are walking multiplier wilds. These can appear at random and move down one position during a base spin. And watch out for the brain icons. Collect enough of these symbols and play them at Bronze, Silver, Gold, or Platinum level.
