    Mighty Griffin Megaways: Jackpot King Slot 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

    A chain reaction is caused by all winning symbols, as they are removed from the reels and replaced by new symbols which drop down from above.

    There are symbol positions above reels 2-5, which help you complete wins, and Wild symbols can only be unveiled in these positions. These are replaced from the right.

    When no more winning symbols are generated, cascades will cease.


    A maximum of seven symbols can be revealed on each reel, while a maximum of 117,649 ways to win are available on each spin.

    A win is awarded when you match consecutive symbols, regardless of height, from left to right, beginning on the left-most reel.

    All of the winning combinations are added together.

    Wild Symbol

    The Wild symbol can only land in the positions above reels 2, 3, 4 and 5, and it can be used to complete wins by replacing other symbols with the exception of Scatters.

    Only the highest win is paid on each winning combination.

    Mystery Symbol

    The Mystery symbol is able to be displayed anywhere on the reels, and all Mystery symbols on screen will reveal the same random symbol.

    The Mystery symbol is not able to reveal Scatter symbols.


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

    Scatter wins are awarded on top of reel wins.

    Three Scatter Symbols appearing on the reels will trigger Free Spins, and if you activate that feature with more than three Scatters then extra free spins will be granted.

    Any Bonus symbols are locked in place before the reels re-spin. 

    If any further Bonus Symbols land in view they are also locked in place, and after that the reels will re-spin once more.

    This continues until no further Bonus symbols land in view, or you can see a reel made entirely of Bonus symbols.

    Based on the amount of Bonus symbols on the reels, you will receive a specific number of free spins.

    Free Spins

    There is an unlimited win multiplier active in this feature, starting at 1 and increasing by 1 following each cascade.

    During Free Spins the positions above reels 2, 3, 4 and 5 have the ability to display Free Spins Scatters, and these will give out additional 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 Free Spins will be used for the duration of the feature.

    When Free Spins has finished, you will see the total winnings for the spins displayed.

    Any winnings will be credited to your account, and once that's done regular play will resume.


    You can choose to gamble the number of spins you start with before playing Free Spins.

    If you elect to gamble, then you could win additional bonus streaks, which spins the main game reels for the opportunity to award more bonus symbols and extra free spins.

    A winning outcome will award the relevant number of re-spins, whereas if you lose then you are returned to the base game.
