Diamond Inferno Bonus Features

As you spin the reels of Diamond Inferno, you’ll have the possibility of triggering one or two special features. These enhance the slot overall, allowing you to have an exhilarating experience. From wilds and respins through to multipliers, there’s plenty to go at with this Triple Edge Studios release.

Expanding Reels

Once you load up Diamond Inferno, you’ll see that the active area begins with the bottom 5 reels and 3 rows. After every consecutive win, you will see the row expand by one. With each additional row that comes into play, an extra 10 paylines also become active in the game. The maximum active play area of this game stands at 6 rows large.


The wild symbol in this slot is on fire, and every time it shows up on the central three reels, it will substitute for all other standard symbols in the slot. The only symbol it won’t stand in for is the scatter.

Scatter Symbol

Scatter symbols can appear on reels 2, 3 and 4 in the Diamond Inferno slot. The smouldering blue diamond represents these, and if they appear anywhere within the active play area, then scatter pays are rewarded to you. Each scatter pays out individually, and you can win up to 20x your stake from this symbol.


There are no free spins as such in the Diamond Inferno slot, but every time you form a winning combination, you’ll get to trigger a respin. Naturally, the win will also trigger the expanding reels, ensuring that you stand more chances of forming additional wins and, in the process, additional respins.

Multiplier Trail

You’ll also see that the game’s multiplier trail becomes active once the maximum number of rows has been brought into play. Should respins continue at this point, then the highlighted multiplier will apply itself to all wins from the respin. This can reach a maximum of x10, as the multiplier increases after every subsequent respin.

Diamond Inferno Jackpot

The Diamond Inferno slot game doesn’t have its own specific jackpot for you to win, but this shouldn’t stop you from trying to win big during gameplay. The highest payout that you can obtain from playing it is an astonishing 11,750x your bet.

RTP and Volatility

This is a medium volatility slot release, so you’ll be able to get some nice payouts from spinning its reels, with rewards coming at an average and steady pace. The RTP rate is 96.19% for the game, so you should get some decent gameplay out of it too.

Where to Play Diamond Inferno

Visit Triple Edge Studios and Microgaming casinos and come out with as many diamonds as you can carry in this wonderfully inventive slot. Our casino experts say that Pelaa, Karamba and Leo Vegas are a good choice for playing Microgaming games, plus they come loaded with some exciting bonus offers.
