    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.

    Jackpot King Promotional Pot System

    While playing any spin, you could activate the Jackpot King Bonus by achieving four Jackpot King overlay symbols in the positions.

    The Jackpot King Promotional Pot System is available on any stake on any game plugged into the Jackpot King Promotional Pot.

    Spin the reels to accumulate Crown symbols, which will enable you to move up the win ladder. 

    Collect at least 15 Crown symbols, and you will gain entry to the Wheel King section of the feature.

    Select an icon after any spin to reveal one of the following outcomes:

    - Spin - spins the reels again, with any extra Crown symbols in view being added to the win ladder.

    - Collect – the feature will end, and you are granted a Bonus Win based on the multiplier of your total bet reached on the win ladder.

    - Wheel King - reveal this to go directly into the Wheel King round of the feature.

    Achieving a minimum of 15 Crown Symbols while playing the Jackpot King Bonus will unlock the Wheel King Bonus.

    The Wheel King Feature is a Tombola style Wheel which hosts Big Win Multiplier segments and Progressive pot segments.

    Spin the wheel to win either a Big Total Bet Multiplier or a Promotional Jackpot.

    You can only win the Jackpot King Promotional Jackpot during the Wheel King part of the bonus.

    When the Promotional Pot is won, it is reset and then it will start to rise again.

    It is not possible for simultaneous jackpot to take place. 

    Should two players seemingly win the jackpot at the same time the first player to trigger the jackpot will win the whole jackpot amount, the second player would win the reserve pot in addition to any further contributions made.

    In the event of a communication error after a promotional pot win result has been determined and before it has been displayed on screen, the win amount will automatically be transferred to the player's account.

    While the game is live, the jackpot cannot be terminated. The outstanding pool amount can be transferred to another jackpot if the game is removed.

    Return to Player

    Return To Player (RTP): 95.46% + 0.50 Jackpot contribution.

    The expected return is the amount we pay out to players relative to the amount of wagering on the game.

    For example, if we take £100 of wagers we will, on average, pay out £95.46 of wins, plus the chance to win the jackpot.
