Aureus Slot Review

Meet Jupiter in front of the Roman cathedral and try to collect golden Roman Coins in the latest slot game by Grazy Tooth Studio called Aureus. Powered by the CoinVerge mechanic, you’ll trigger symbol upgrades, collect cash prizes, apply a multiplier or randomly trigger a respin for a chance to win 2,431x your bet. With the clean-cut design and vibrant imagery that reminds of an animated film, the Aureus slot is definitely a refreshing title when it comes to Ancient-themed slots. Below we’ll take you behind the gameplay and in-game features of this slot game.

About Aureus Slot 

The Aureus slot is a history-themed title developed in partnership with Crazy Tooth Studio and Microgaming. As we’ve mentioned previously, Aureus is another term for gold coins, and you guess that the overall reel action revolves around the coins. They’ll show up on a rather unusual 3 reels and 5 rows. Here, the engine does not form paylines because wins are created with the help of the CoinVerge mechanic. This means that the grid creates coin collection areas, and in order to win, you need to land two brackets on both sides of the area.
Bets range between £0.20-£80 per spin. Make sure to click on the coin button placed above the spin button and adjust your preferences just before you spin the reels. You’ll benefit from various extras and bonuses such as the random Respins and the Lightning Feature we’ll discuss below. This bonus selection, coupled with the highly volatile math model, will win you a maximum of 2,431x your stake.

Design, Symbols and Graphics 


Developers have made a classy 90’s cartoon theme regarding the design of the Aureus slot. As soon as you start the game, you’ll find yourself on top of the mountain, where you can clearly see the bright blue skies. Reels are transparent and levitate during gameplay, giving a light feel to the overall template. From the left side of the reels, you’ll see Jupiter holding a thunder-shaped cane, keeping an eye on your reel strategy. The background effect and ambient light music complement the overall atmosphere as you’ll almost feel the light mountain breeze.
On the paytable, you’ll see a collection of Roman Coins that differ in their value. They’re split into low, medium and high category. All coins land with fixed cash values attached to them. So, the lows will land with a value of up to £0.20, mediums in the range of £2.4-£3 and highs between £12-£200. There’s another side of the coin when it comes to special symbols during the bonus round, as they’ll lead to triggering different modifiers and reel feature. But we’ll reveal those in the bonus section, now onto the math model.

RTP, Variance and Payouts for the Aureus Slot 

The theoretical Return to Player percentage of the Aureus slot is 96%, which is straight up the industry average. The variance tends to be on the medium side, so there will be smaller wins during gameplay. Once you proceed to the bonus rounds, the chances to trigger a bigger prize will significantly increase. All in all, you can end up winning up to 2,431x the stake from a single spin, thanks to the bonus features.

Gameplay and Features on Aureus Slot 

aureus-slot-featuresThe bonus games on the Aureus slot heavily rely on the CoinVerge mechanic. As we’ve mentioned previously, you’ll get closer to the Aureus slot’s maximum payout with the help of Respins and Lightning Feature. Both of them are triggered randomly at any spin, so let’s see how they work in more detail: 

Respins Feature 

During the base game, you can randomly trigger a respin where one or more of the following special symbols may appear on the grid. If they land in the winning collection area, you’ll be awarded the suitable prize:

  • Multiplier Coin - multiplies the prize by 2x-5x;
  • Upgrade Coin – upgrades low and medium coins to high and wins you an additional high-paying coin;
  • Collect Column Coin – collects all coins on the respective reel;
  • Collect All Coin – collects all coins on the grid;
  • Respins Coin – wins you 2,3 or 5 respins.

During this feature, the triggered area stays active until the end of the game and makes a new payout calculation on each spin. Moreover, you can retrigger this feature up to 8 times for a chance to win different prizes.

Lightning Feature

This feature is triggered randomly during gameplay. As soon as you land a closing bracket anywhere on the grid, Jupiter may strike the reels with its thunder cane and add an opening bracket on the same row. This way, it will help you form a win an boost your total.

Aureus Slot on Mobile 

The Aureus slot is mobile optimised and can be played on any desktop, mobile and tablet devices. It is developed with HTML5 and can adjust to any small screen on any operating system. The high-quality design and graphics are appealing when playing on mobile devices too.

Other Microgaming Slots 

Microgaming is probably one of the most popular slots developers in the industry that has launched many impressive titles regularly played at online casinos. If you’re a fan of gold-mining titles, check out Gold Collector, an exciting title developed in partnership with All41 Studios. Powered by the HyperHold engine, it will certainly catch your attention. Or, maybe you could immerse in a Tiki-themed adventure called Maui Mischief that will introduce, colourful, lighthearted design coupled with few lucrative bonus features. Finally, check out the debut title of Microgaming and Stakes Entertainment called 8 Golden Skulls of Holly Roger Megaways. Powered by the Firepot engine, you’ll definitely have fun while you spin the reels out on the open sea.

SlotsWise Verdict 

The Aureus slot is a decent slot game with an unusual design and grid mechanic. If you haven’t played a slot game powered by the CoinVerge mechanic, you’d probably be confused on how to form a winning combination since symbols don’t match on the grid. However, once you figure out the concept, it will definitely entertain you and offer you a different reel play experience. The maximum payout of 2,431x your stake is modest, but considering the medium variance and average RTP, it’s pretty balanced. If you’re new to online slots or prefer medium over high variance reel action, we warmly recommend you try the Aureus slot and experience the power of the coin reel mechanism.
