    Mighty Griffin Megaways: Jackpot King Game Overview

    The bet sizes available in Mighty Griffin Megaways: Jackpot King range from 10p to £10.

    There are up to 117,649 paylines available in this game. 

    Cascading Symbols

    All winning symbols will cause a chain reaction, which sees them removed from the reels, and they are substituted by new symbols coming from above the reels.

    There are symbol positions above reels 2-5 which help the formation of wins, and Wild symbols can only be revealed in these positions. These will be replaced from the right.

    Cascades will stop when winning symbols are no longer generated.


    Each reel can reveal up to seven symbols on it, with up to 117,649 ways to win on each spin.

    When you match consecutive symbols you are awarded a win, irrespective of height, from left to right, beginning on the left-most reel.

    All of the winning combinations are then added together.

    Wild Symbol

    The Wild symbol can only be displayed in the positions above reels 2-5, and it can be used to complete wins by replacing other symbols except Scatter symbols.

    Per winning combination, solely the highest win is paid.

    Mystery Symbol

    The Mystery symbol can appear in any position, and the same random symbol is revealed by all Mystery symbols that land on the reels.

    The Mystery symbol is not able to reveal Scatter symbols.


    The Scatter symbol can appear in any of the reels, although it cannot land in the positions above reels 2, 3, 4 and 5.

    Scatter wins are awarded in addition to reel wins.

    When three Scatter Symbols appear on the reels, Free Spins is triggered.

    If you unlock Free Spins with more than three Scatter symbols, you receive extra free spins.

    Any Bonus symbols will be locked in view prior to the re-spin. 

    If any further Bonus symbols land in view, they remain in their positions before the reels re-spin once more. 

    This continues until no further Bonus symbols land in view, or a reel entirely made up of Bonus symbols is displayed. 

    You are granted a number of Free Spins based on the number of Bonus symbols that are on the reels.

    Free Spins

    Throughout Free Spins, an unlimited win multiplier is in play which begins at 1, increasing by 1 following each cascade.

    During this feature, the positions above reels 2, 3, 4 and 5 are able to reveal Free Spins Scatters, which will give out more free spins.

    - Three Free Spins Scatters = five extra free spins.

    - Four Free Spins Scatters = 10 extra free spins.

    The stake that was used to trigger the feature will be used for the entirety of Free Spins.

    When Free Spins concludes, the total winnings for the spins will be displayed.

    Your account is credited with any winnings, and regular play then resumes.


    Prior to the start of Free Spins starts you can choose to gamble the number of spins you begin with.

    Gamble for the chance to secure additional bonus streaks, which spins the main game reels for the chance of awarding extra bonus symbols and more free spins.

    A winning outcome will award the relevant number of re-spins, while an unsuccessful gamble will take you back to the base game.
