The Demon Code Features

Enter the Void 

The Enter the Void feature is triggered after players experience an unsuccessful cascade and more than one or more wild symbols remain on the grid.

All of the applicable wild symbols that remain on the grid (as well as ones sharing a horizontal edge, vertical edge or corner with the wild) are removed from the game, allowing for a new cascade. 

If a win still does not occur after symbols have removed it will retriever, this can continue indefinitely. 

Demon Modifiers

There are 4 Demons sat on the outside of the game grid, each Demon has a corresponding talisman symbol that may appear on the game grid following a successful cascade.

Whenever the talisman symbol appears the Demon Power associated with the colour will kick in.

Green Demon - Ancient Alchemy

Mystery symbols are randomly added to the game grid, with all mystery symbols being the same. 

Blue Demon - Cryptic Chaos

One random symbol type on the reels is chosen to pay anywhere.

Purple Demon - Dark Design

Wild symbols are randomly added to the game grid. 

Red Demon - Fiery Fusion

A large 3x3, 4x4 or 5x5 symbol block is added to the game grid.

Free Games Bonus

Whenever players collect 4 scatter symbols on the meter in one single game round then they'll trigger 10 free spins. Every scatter collected after the 4th will increase the number of free spins by +2.

Whatever the player's win multiplier is before the free game triggers will be carried over into the bonus. This will continue to increase by +1 whenever a cascade occurs.

At the start of the free games bonus the game grid will increase in size by one row, every 4 scatters that are collected during this time increases the number of rows by +1 and awards 2 extra free spins. The maximum number of additional rows that can be added to the game is 12.

The Demon Code

The Demon Code is a 6x6 Cluster Pays slot that takes players deep into the underworld in what's a terrifyingly good slot developer by SG Digital and NextGen. Players can benefit from cascading wins, 4 demon random modifiers and of course free spins with an increasing multiplier. So there's plenty to play for! 


This dark, ominous horror-themed slot is set deep in the depths of a monster-filled dungeon. Demons lurk around each corner of the game reels that are hover above a fiery hole in the floor that looks like the entrance to the depths of hell. 

Low paying symbols in The Demon Code are green, blue, pink and red gems, whilst high paying symbols are green, blue, pink and red crystal balls that are being gripped by a demon claw. The special symbols include a stylised W for the wild, a demon's eye for the scatter symbol and four Demon Summon symbols.

In terms of the game's soundtrack, as you would expect NextGen and SG Digital have come up with a wonderfully spooky track that fits the aesthetic of this game perfectly. 


This is your typical cluster pays slots, whenever players manage to land a cluster of 4 or more matching symbols together one the reels then they'll be removed from the game screen, leaving space for new symbols to fall into place creating a chain reaction of wins.

To the left of the game reels on a floating rock is a multiplier (starting at 1x) that increases by +1 every time players register a winning combination.

The traditional action bar you'd find in most slots has been replaced with what's easily the weirdest substitute, a play button that looks like it was taken right from a classic mid-2000s era iPod. 

Surrounding the play button are four smaller buttons that allow players to increase and decrease their stake, set automated spins and access the game's payable and bonus information.

Win Potential

This medium/high volatility slot has ranging RTPs with the base game average being 96.26%. The maximum win players can trigger in this slot is 12,500x their initial stake.

Our Verdict

There's a lot going on in The Demon Code, if you're not intimidated by cluster pays slots with a lot of bonus features and somewhat strange mechanics to get your head around then we genuinely think you'll have a good time playing this slot. It offers genuinely enjoyable cluster pays action and has a pretty good win potential!
