    Mighty Griffin Megaways: Jackpot King Online Slot Game Overview

    You can play Mighty Griffin  Megaways: Jackpot King from just 10p per spin.

    This game uses the  Megaways mechanic, which offers up to 117,649  ways to win.

    Cascading Symbols

    Winning symbols cause a chain reaction on the reels.

    All symbols involved are removed from the reels and replaced with new ones from above.

    Symbol positions sit above reels two, three, four and five, helping you to secure wins.

    Wild symbols can only land in these positions - they are replaced from the right.

    Cascades end when winning symbols stop landing.


    Each reel can reveal up to seven symbols and each spin offers a maximum of 117,649 ways to win.

    Match consecutive symbols from left to right, starting with the left-most reel, to secure a win. 

    All winning combinations are combined.

    Wild Symbol

    This can only land in the positions above reels two to five.

    Wilds override all other symbols except for Scatter symbols. 

    You'll be paid the highest win on each winning combination only. 

    Mystery Symbol

    Mystery symbols can land anywhere on the reels. 

    Should one appear, it will reveal the same random symbol apart from Scatter symbols.

    Scatter symbol

    This may land anywhere apart from the positions above reels two to five.

    Any Scatter wins are added to reel wins.

    Should three Scatter symbols appear, Free Spins will be enabled - the more Scatters that you trigger this Bonus feature with, the more free spins you'll be awarded.

    Bonus symbols remain in place for the duration of the re-spin. 

    If extra Bonus Symbols land while playing Free Spins, they too are locked in place and the reels re-spin again.

    This continues until there are no Bonus symbols present, or if they fill an entire reel.

    The number of Free Spins you receive depends on the number of Bonus symbols on the reels.

    Free Spins

    Free Spins is played with an unlimited win multiplier, starting at one.

    It increases by one after every cascade.

    While playing Free Spins, Free Spins Scatters may land in the positions above reels two, three, four and five.

    Should one land, you'll receive extra free spins:

    - Three Free Spins Scatters = five extra free spins

    - Four Free Spins Scatters = 10 extra free spins

    The stake used to trigger Free Spins is used throughout this Bonus round.

    Your total winnings will be shown at the end of the feature and credited to your account.

    Regular play then resumes.


    It's possible to gamble the amount of spins you start with before playing Free Spins.

    If you chose to gamble, you have the chance of winning extra bonus streaks. 

    This will see the main game reels spin and you could potentially win extra bonus symbols and/or free spins.

    Should you secure a winning combination, you'll be awarded the corresponding number of re-spins; lose and you'll return to the base game.

    Jackpot King Promotional Pot System

    It is possible to trigger the Jackpot King Bonus on any spin. 

    This happens if four Jackpot King overlay symbols land in the positions.

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

    You need to spin the reels to try and collect Crown symbols - these allow you to climb the win ladder.

    15 or more Crown symbols will permit you into 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 and any extra Crown symbols that land are added to the win ladder

    - Collect – the feature terminates and you'll receive a Bonus Win based on the multiplier of your total bet reached on the win ladder

    - Wheel King - grants you direct access into the Wheel King round of the feature

    Secure at least 15 Crown Symbols during the Jackpot King Bonus to unlock the Wheel King Bonus.

    The Wheel King Feature is a tombola-style wheel with Big Win Multiplier and Progressive pot segments up for grabs.

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

    It is only possible to win the Jackpot King Promotional Jackpot while playing the Wheel King part of the bonus.

    When the Promotional Pot is won, it re-sets and starts to rise all over again.

    Simultaneous jackpots cannot take place. 

    If two players win at the same time, the first player to trigger the jackpot wins the total jackpot amount and the second player is awarded the reserve pot as well as any further contributions made.

    If there's a communication error after a promotional pot win result has been determined and before it has been shown on screen, the win amount will be automatically 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.
