Symbols for Black Diamond Slots

Special symbols

  • Wild Symbol

    Black diamond. This substitutes for all other symbols to create winning combinations, except for the scatter and bonus symbols.

  • Bonus Symbol

    Three gold bars. If you land three of these symbols you'll trigger a bonus game.

  • Scatter Symbol

    Jewel with word ‘scatter'. This symbol has the power to activate the free spins round.

Bonus games and features

Black Diamond includes a lucrative bonus game and a free spins round, both of which are activated at random from within the base game. Here's how to trigger it.

  • Bonus Game

    To activate the bonus game, you need to line up at least three gold bar icons. These icons appear on the second, third and fourth reel. The payline they appear on will need to be active in order for the feature to be triggered. If you do this successfully, you'll enter a bonus game with potential winnings of 40-600 coins.

  • Free Spins Round

    Black Diamond's free spins round is easier to trigger than the free spins rounds of many other online slots, as it's activated by only two scatter symbols. If you manage to land scatters on the first and last reels, you'll be awarded 10 free spins automatically.


As you might expect from a game that's themed around wealth and luxury, the jackpot of Black Diamond is a considerable sum of money. There's a maximum jackpot of $30,000 on one spin, as long as you play the max bet of $125. That doesn't take the bonus round and special features into account though, so the true jackpot potential is even bigger!
