    Thunderstruck Wild Lightning Game Overview

    The bet sizes available in Thunderstruck Wild Lightning range from 20p to £16.  

    Betting in this game is fixed at 40 paylines. 


    Wild Symbols

    Wilds substitute for all symbols except Scatters and the Thunderball symbol.

    In the base game, they can appear stacked.

    If a Wild is involved in a base game win, it pays out 2x or 5x.

    Wilds can create their own winning combination when appearing in a payline combination.


    Scatter Symbols

    Scatters can create their own winning combination.

    Scatter wins are multiplied by the total bet and added to regular wins.


    Thunderball Symbols

    Thunderball symbols award cash or jackpot prizes.

    Blue Thunderballs can land on any reel during the base game, while gold Thunderballs can land on reels four and five only.

    Gold Thunderball are collected each time one lands. 

    Thunderball symbols cannot create their own winning combination.

    Changing the bet size in the base game will change the cash prizes available on Thunderball symbols.


    Link & Win

    Land at least six Thunderballs in the base game to trigger this feature and win three initial spins. 

    The round commences with four rows open and four rows locked.

    Only Thunderballs and blank symbol positions are available in this feature.

    There are two types of Thunderball symbols in Link & Win:

    • Regular Thunderballs display cash prizes and can land on any row 
    • Thunderball symbols displaying jackpot prizes, which can only appear on rows five to eight

    All triggering Thunderball symbols will lock in place at the start of the round and remain until the end. 

    Remaining symbol positions spin independently.

    Should any more Thunderballs land while playing, they will also lock in place until the end and your number of spins will  reset to three.

    Landing Thunderball symbols also gives you a chance to unlock more rows:

    At the end of the feature, every cash and jackpot prize on the unlocked rows will be awarded.

    When all spins have been used or every reel position is filled with a Mega Jackpot symbol, this feature will end - the latter will also award the Mega jackpot.

    • Mega jackpot - awards 15000x the total bet
    • Major jackpot - awards 150x the total bet
    • Minor jackpot - awards 50x the total bet

    Doing so will grant you extra spins equal to the amount awarded at the start of the feature. 

    If exactly two Scatters land on a single spin, they will be collected on the Scatter collector.

    The Scatter collector resets at the end of the Wild Storm feature.

    Free Spins are played automatically.


    Wild Storm Feature

    This feature may trigger during Svartalfheim Free Spins.

    It can turn up to five reels into Wild reels.

    Wild reels pay out as separate symbols.

    If you do not win during the Wild Storm feature, the Scatter collector will be refilled - the Scatter collector resets at the end of the round.

    The Wild Storm feature cannot re-trigger.

    Bets are the same as the triggering spin and any wins are added to base game wins.


    Wild Lightning Feature

    In Free Spins, if Wilds land on reels two, three and four, this feature will be enabled. 

    Triggering Wilds will activate the symbol positions they land on.

    Any Wilds that land on an activated position will turn that reel Wild for that spin. 

    Once a reel has turned Wild, those symbol positions will be deactivated.

    Random symbol positions can already be activated when entering the Free Spins features:

    • Vanaheim free spins - a maximum of one activated position
    • Alfheim free spins - up to two activated positions 
    • Nidavellir free spins - up to three activated positions 

    Wild Reels pay out as separate symbols.

    You cannot trigger the Wild Lightning feature during Svartalfheim free spins.


    Return to Player 

    Return to Player (RTP): 96.10%. 

    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 £96.10 of wins.
