    Diamond Mine Megaways: Jackpot King Slot - How to Play

    Play with up to 117,649 paylines on Diamond Mine Megaways: Jackpot King.

    This slot features the Megaways mechanic.


    In this slot, a maximum of seven symbols can land on each vertical reel.

    The Megaways mechanism is in play, meaning you can play with up to 117,649 paylines with each spin!

    To win, land adjacent matching symbols on the reels. Wins pay out from left to right.

    At the end of each spin, wins are evaluated before being added together and multiplied by the wager value, then paid.


    Symbol cascades are active in this game.

    Following a win, all symbols incolved will disappear from the reels. New symbols will cascade down from above to fill their places.

    This can lead to a chain reaction of consecutive wins!

    Symbol cascades will stop once there are no more available wins. 

    Wild Symbols

    Wilds override all symbols except Scatters to help create wins.

    They can only land in the symbol positions above reels two, three, f0ur and five. 

    If there are multiple possible wins in a single combination, the highest one will pay out.

    TNT Symbols

    TNT symbols can land anywhere on the reels.

    TNT symbols act as mystery symbols and can transform into any random symbol, with the exception of Scatters.

    Scatter Symbols

    Land four Scatters to be awarded 12 free spins.

    For every extra Scatter that appears above four, you'll win an extra five free spins. 

    Scatters can appear on any reel apart from the positions above reels two, three, four and five. 

    Scatter symbol wins are added to payline wins before paying out.

    Free Spins

    In Free Spins, you play with the same bet value as that of the triggering spin.

    During the Bonus game, a win multiplier is in play.

    The multiplier starts at one and increases by one following each Cascade.

    There is no upper limit to this multiplier, meaning there is potential for big wins!

    Free Spins Scatters can appear in the positions above reels two to five during this feature. 

    Land three to win five additional free spins, or four for 10 additional free spins!

    Wins pay out at the end of the feature, and standard gameplay will then resume.
