How to play  

Diamond Inferno is a 5-reel video slot where there are a minimum of 3 rows of symbols in play, which can expand to a total of 6 rows. Likewise, there is a minimum of 20 paylines in play on every spin, but this expands with every win up to a maximum of 50 lines, with every win granting a free re-spin (The game re-sets to 3 rows and 20 paylines when no win occurs).

Wins pay left to right (except for scatter wins, which pay anywhere on the reels), and are multiples of the line bet (scatter wins are multiplied by the total wager). The minimum bet is £0.20, with a maximum wager of £20.

The Diamond symbol is the scatter and hitting 3x or more scatter symbols in the active play area triggers the Scatter Pays feature, where each scatter pays out individually but the value is determined by the row on which it appears.

  • Wild symbol appears on reels 2, 3 and 4
  • Wild substitutes for all other symbols, except the scatter
  • Hitting 5x Star symbols = 2,000x line bet (up to £2,000)
  • Hitting 5x Lucky 7 symbols = 120x line bet (up to £120)
  • Hitting 5x Bar symbols = 80x line bet (up to £80)
  • Hitting 5x Dollar Sign symbols = 55x line bet (up to £55)
  • Hitting 5x Dice symbols = 45x line bet (up to £45)


The maximum payout you can win on Diamond Inferno is 11,750x total bet (£235,000 when betting the max), when all 6 rows of symbols and all 50 paylines are in play. The biggest single payline win is £20,000 for hitting 5x Star symbols with the 10x multiplier in play, again when betting the maximum coin size.

Diamond Inferno is a medium volatility slot game with a 96.19%RTP.

Special features

Expanding Reels

Base play begins with an active play area consisting of 3 rows of symbols. This expands by 1 row after every win, and with each new row, 10 paylines are also added. The maximum play area is 6 rows, with a maximum of 50 paylines in play. After a losing spin, both the rows and paylines reset to 3 and 20 respectively.

Multiplier Trail

The Multiplier Trail is activated after the maximum active play area of 6 rows is unlocked. A 2x win multiplier is applied to all wins from the current re-spin, and continues to be increased with each win and subsequent re-spin, up to a maximum of 10x.

Scatter Pays

Hitting 3x or more scatter symbols in the active play area triggers the Scatter Pays feature. Each scatter pays out individually, with the value of each Scatter Pay being determined by the row on which it appears:

  • Scatters on row 6 = 20x total bet (up to £400)
  • Scatters on row 5 = 10x total bet (up to £200)
  • Scatters on row 4 = 6x total bet (up to £120)
  • Scatters on row 3 = 4x total bet (up to £80)
  • Scatters on row 2 = 2x total bet (up to £40)
  • Scatters on row 1 = 1x total bet (up to £20)

Graphics and Sounds

The design of the game makes it ideal for playing on the smaller screens of smartphones and tablets, with the actual playing area being smaller than it is on most slot games. The reels are set against a fiery, hellish background, and flames burst into life after each winning spin when the reels expand. The symbols pay homage to ‘traditional’ slot game design, with Lucky 7. Bar, dollar signs and card symbols.

The music is driving guitar rock throughout, but this goes up a notch after a winning spin and the reels expand, adding to the sense of drama and anticipation. Like all Triple Edge Studios slots, music and visuals combine perfectly to create a total gaming package.


Triple Edge Studios has managed to build a reputation for innovation in slot game design, with Diamond Inferno being no exception. The reel expansion feature means the gameplay is constantly evolving, while the unusual Scatter Pays adds another dimension to a fairly standard slot game feature. These gameplay highlights are topped off by an exceptional design and a powerful soundtrack, and as it’s slot designed very much with mobile play in mind, you can be sure it will look good no matter the device you play on.

If you like bringing the heat to your slots gameplay, check out Diamond Inferno for yourself at one of our recommended UK slot sites.
