Visual and Sound Insight

Aurum Codex is an alchemy-themed slot from Red Tiger Gaming (release date: November 12, 2020). The slot provider distances itself from fantasy tropes, instead offering up a palette of dark rooms with glass jars, brass tools, and indecipherable texts.

During the testing process, considerations became clear right away:

We liked the colour contrast, largely bronze and dark gold, which made for a screen that you could continue to play without feeling too fatigued, even after much play.
The animation was slow, featuring restrained movement that wasn’t dull but also didn’t add excessive motion to keep spinning.
The soundtrack uses faint echoes, turning pages, and quiet chime effects to reinforce the alchemist’s theme without becoming distracting.

The Aurum Codex slot game adopts a more methodical tone, eschewing the fantastical illustrations seen in previous titles from Red Tiger, such as The Shadow Order.

Main Mechanics and Payout Model

The Aurum Codex slot operates through a traditional spin-and-match configuration, awarding payouts to players who exhibit three or more matching symbols from the first reel in the payline. A key differentiator of the game is the unique wild mechanic, which aligns with the theme of alchemy.

Symbols

Symbols divide into three groups:

Low-value: 10, J, Q, K, A.
High-value: Key, Scroll, Skull, Scales, Book.
Special: The Alchemy Wild shows a golden seal with an alchemical circle and Scatter symbols shaped like an hourglass.

The payout balance is deliberate; highs and lows keep an even pace, while the Golden Wild mechanic prevents the grid from feeling static. The result is a payout structure that feels fair for a high-variance slot and keeps the overall payout cycle consistent across long test sessions.

Bonus Features

The Aurum Codex slot machine does not overload the field with mini-games. Instead, it focuses on two key mechanics:

Wild Alchemy: When two Alchemy Wilds appear on the same row, every symbol between them becomes a Golden Wild, creating the chance for full-row wild wins worth up to 15× the stake. This feature can trigger during both base and bonus rounds.
Free Spins: Three Scatter symbols on the middle reels start 10 free spins. The hourglass may rotate to add 5 or 10 extra spins, reaching a maximum of 20. During this round, all Alchemy Wilds remain locked in place, which can connect several Golden Wild lines simultaneously and raise the payout potential.

The best strategy for reaching Aurum Codex’s payout potential is to trigger extra free spins via the hourglass feature. Additional spins are rare but can create several golden wild rows at once, so maintaining a steady bet helps sustain play.

Below is the complete pay table, outlining how each symbol contributes to Aurum Codex’s max win potential during both base and bonus rounds.

Symbol	3 on Line	4 on Line	5 on Line
Ten	4×	10×	20×
Jack	6×	16×	30×
Queen	10×	20×	40×
King	16×	30×	60×
Ace	20×	40×	80×
Key	24×	50×	100×
Scroll	30×	60×	120×
Skull	40×	80×	160×
Scales	60×	150×	300×

Next, we’ll explain how to play Aurum Codex.

Layout and Controls

This online slot is played on a 5×3 grid with 20 fixed paylines. All wins are paid from left to right according to the total bet placed. Betting starts at £0.10 and can reach as high as £5 per spin (some casino sites may advertise a slightly higher bet limit). The player can adjust the amount they have wagered using the + / – buttons, located on the lower panel. The game has an RTP of 94.7% and is a high volatility game.

The control bar is where you will find the Spin and Autoplay buttons, as well as access to the pay table and settings options. The Autoplay option will only allow for limited alterations to the spins but is reliable as a test to try different betting approaches. The buttons for sound and information, both located at the top right of the screen, are accompanied by a link to responsible play tools.

I found the interface responsive and uncluttered. Autoplay behaved predictably with no delay, and the bet steps feel fair for moderate stakes. This online slot suits players testing mid-range strategies rather than all-in approaches.

Real Feedback

Our team ran multiple Aurum Codex tests to assess how the base game flows, how often features appear, and how the bonus rounds influence the payout curve.

During testing, the Alchemy Wilds appeared rarely but delivered strong results when two landed on the same row, turning all symbols between them into Golden Wilds and creating a 35× payout. After around 150 spins, I triggered the Free Spins round with three hourglass Scatters, which extended to 20 spins after two extra turns of the hourglass and paid roughly 180×. Even in sessions without bonuses, the wild conversions kept the base game active. The slot’s high volatility feels steady rather than erratic, so keeping a moderate stake helps balance longer play and maintain control over the payout flow.

Verdict

Aurum Codex has an understated sense of inevitability. Instead of relying on noise or hazards, Aurum Codex plays to rhythm and patience. The alchemy theme is more than visual, as these symbols alter the behaviour of the slot. The addition of Locked Alchemy Wilds, along with the increasing Golden Wilds function on all features, had me feeling like each spin was purposeful. The Free Spins feature, which introduces an elongated tension with the hourglass mechanic, also invites measured bursts of fun. Players in the UK can check out or play Aurum Codex for fun before committing and staking real money.

Pros:
Golden Wild and Alchemy Wild mechanics
Strong 4,131× max win potential
Consistent visuals and sound design
