The Demon Code review

Is it cascading wilds you’re after, or cluster pays? Maybe you prefer free spins or even mega symbols? Well, when it comes to The Demon Code, your wishes will be met as this online slot has it all.

The hell-themed offering from NextGen Gaming throws you into the other realm as you navigate a feature-packed game with a good RTP and maximum win.

How I tested The Demon Code

I have always been intrigued by cluster pay slot machines, so I was keen to get my hands on this and give it a test. I jumped online, deposited it into my pot, and began exploring for my review.

  1. I have actually played the game. You will come across reviewers peddling feedback on a game they haven’t even played and instead are reviewing it based on information they’ve been given.
  2. The RTP and the volatility are two very important stats you should consider if you will play a slot review. I looked at this before playing The Demon Code.
  3. I genuinely think graphics are an important consideration, and no one will play a boring and colorless-looking slot.
  4. I think a slot should be open to players with all types of budgets, so I always consider the minimum and maximum bet.
  5. I take a look at understanding the symbols before I start playing. This isn’t completely necessary as you will tend to pick them up as you go.

The statistics and technical data for this game are not the most headline-grabbing, but this game is all about the endless features. This is where the excitement comes, so let’s take a look at them.

Game Features

This is the meaty part of this review because The Demon Code is jam-packed full of features and bonus games.

Wilds, free spins, and other features


Any symbols involved in a winning combination disappear, so new symbols essentially cascade or drop to fill in any gaps in the grid area. The falling symbols may generate another win. In this case, the cascade will continue until the grid is full and no wins occur.

Enter The Void

This is triggered after an unsuccessful cascade, i.e., a cascade where not a single win was generated by the falling symbols and a wild remains on the grid. In this case, the wild and all the symbols surrounding it disappears, and a new cascade occurs.

Win Multiplier

On the top left-hand corner of the grid is a floating rock displaying a win multiplier. It starts at 1x and increases for each consecutive win, and remains until a non-win happens. If you make five winning combinations in a row, the multiplier will be 6x, and if the next spin doesn’t generate a win, the multiplier resets back to x1. It has no maximum.

Demon Summons

This is kind of four features in one because it involves the four demons clinging to the side of your game grid. During any random spin, one of four coins can appear. Each coin displays a demon and awards powers to the player which corresponds to that demon.

  • Green Demon – cause mystery symbols to appear on the grid, which all change into one randomly chosen common symbol
  • Blue Demon – causes all instances of a certain symbol to become scatter symbols that do not need to be in a cluster to win.
  • Red Demon – power is to summon a symbol block of three by three, four by four, or five by five, which guarantees a cluster combination.
  • Purple Demon – randomly adds wild symbols to the grid, which increases the likelihood of a win.

Free Games Bonus

The set of eyes above the game grid. These keep count of the amount of scatter symbols you have encountered.

When four or more eye scatter symbols appear in one set of cascades, you enter Free Games Bonus mode. 10 free spins are awarded, plus two for each scatter symbol on top of the original four.

If you collect five scatters, you will start with 12 free spins, which will be displayed in the large central eye. The grid area increases by one row, and for every four more scatters you collect during this mode, another row is added until the maximum of 12 is reached. 

The Demon Code is the meat feast pizza of slot machines!

This game is like they asked every online slot machine player what their favorite feature was and just decided to do them all. Trying to collect the scatters adds a nice little bonus incentive while playing.

The Demon Code Graphics & Sound

Optimized for Mobile👍 
Special Features👍 

The Demon Code has smooth well-realized graphics, which are well in keeping with the theme.

The square grid is set in a dark dungeon with evil red eyes appearing from the darkness. The design is well in keeping with the design. The soundtrack is a little cheezy, which fits well with the more cartoony elements of the graphics.

Solutions if you have some issues with a game

If the game is interrupted during a cascade, the previous bet will be designated as void, and your stake is returned.


NextGen has done well to collate a huge range of features into a game that is still enjoyable. With such a crowded feature library, it can be easy for one to never shine through, but NextGen has these features working well together.

Plus, the game has good technical data and has been well designed. I love playing the dungeon setting with the red eyes shining from the darkness.
