    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.

    Jackpot King Promotional Pot System

    There is a chance that the Jackpot King Bonus can be triggered on any spin, if you land 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 and move up the win ladder by collecting Crown symbols. 

    Accumulate at least 15 Crown symbols to enter the Wheel King section of the feature.

    After any spin select an icon and one of the following outcomes will be revealed:

    - Spin - the reels will re-spin, with any further Crown symbols on screen adding to the win ladder.

    - Collect – the feature will conclude and you receive a Bonus Win based on the multiplier of your total bet reached on the win ladder.

    - Wheel King - reveal this and you will be directed to the Wheel King round of the feature.

    Collecting at least 15 Crown Symbols throughout the Jackpot King Bonus awards the Wheel King Bonus.

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

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

    The Jackpot King Promotional Jackpot can only be won while you are playing the Wheel King section of the bonus.

    The Promotional Pot is reset when it is won, before rising again.

    Simultaneous jackpot wins cannot occur. Should two players appear to win the jackpot at the same time, the first player to trigger the jackpot will win the whole jackpot amount, with the second player being awarded the reserve pot plus 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 your account.

    The jackpot cannot be terminated while the game is live. If the game is removed, the outstanding pool amount can be transferred to an alternate jackpot.

    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.
