Play our electric online slot game Thunderstruck Wild Lightning!
Wilds can become stacked in this game, and multipliers could be included, while you can also unlock the Link&Win feature where symbols are locked in place for re-spins.
There are four jackpots on offer in this game, with a payout worth 15,000x your bet up for grabs if you trigger the Mega jackpot by filling the reels with Thunderball symbols!
Lightning may strike.
The bet sizes available in Thunderstruck Wild Lightning range from 20p to £16.
Betting in this game is fixed at 40 paylines.
You can use Wild symbols as substitutes for other symbols in this game to help finalise winning combinations. Wilds are unable to replace Scatters and Thunderball symbols, however.
During the base game, Wilds multiply wins by either 2x or 5x when substituting in a winning combination.
When Wilds are displayed in a payline combination, they can form their own winning combination.
Wilds can be stacked while the base game is being played.
Scatter symbols can be displayed anywhere on the reels, and they are able to create their own winning combination.
Scatter wins are multiplied by the total bet, which are then added on top of regular wins.
During the base game, Thunderball symbols can land on any reel, and they will appear in either a blue or gold colour.
Every gold Thunderball symbol that lands is collected, and these symbols can only hit on reels 4 and 5.
Thunderball symbols pay during the Link&Win feature, and they are able to grant cash or jackpot prizes, although they are unable to form their own winning combination when they land in any position.
If you change the bet size in the base game, potential cash prizes shown on the Thunderball symbols will be updated.
Unlock the Link&Win feature when a minimum of six Thunderball symbols are shown, although it is only possible to do this in the base game.
You will start the Link&Win feature with three spins, and there will be four open rows and four locked rows.
The reels will only display Thunderball symbols and blank positions during this feature, and these Thunderball symbols can show cash and jackpot prizes.
Regular Thunderball symbols could land on any row, and they will display cash prizes.
Thunderball symbols that land and show jackpot prizes can only hit on rows 5-8 while this feature is active.
The Thunderball symbols that initiated the feature are locked in place, while the other symbol positions will be spun independently.
Whenever a new Thunderball symbol appears, it stays in its position for any spins that follow, in turn resetting the number of remaining spins to three.
It is possible to unlock extra rows when you land a certain amount of Thunderball symbols in the Link&Win feature:
|Number of Thunderball Symbols||Row Unlocked|
All Thunderball cash prizes and jackpots in unlocked rows are paid when the Link&Win feature has concluded.
When you have used all of your spins, or if you have filled all of the reels with Thunderball symbols to trigger the Mega jackpot, this feature will end.
You can trigger jackpots while playing the Link&Win feature:
There are five Free Spins features in this game, and your free spins are automatically played.
|Free Spins Feature||Number of Triggers to Unlock||Free Spins Granted||Wild Multiplier|
|Jotunheim||1||15||2x, 3x or 5x|
|Vanaheim||5||12||2x, 4x or 6x|
|Alfheim||10||9||3x, 5x or 8x|
|Nidavellir||15||6||5x, 8x or 12x|
If a number of Wilds substitute in a win, no additive or multiplicative effect exists.
To re-trigger this feature, land at least three Scatters. You will receive the same number of spins as your initial allocation.
The fifth Free Spins feature is Svartalfheim Free Spins, which can be triggered once you've accumulated 20 Scatter pairs while playing the base game. This feature becomes active on the following Free Spins Selection trigger.
If no more than two Scatter symbols appear on a single spin, they are collected into a Scatter collector.
When you've played the WildStorm feature, the Scatter collector is reset.
When you play Svartalfheim Free Spins, you receive one free spin alongside the WildStorm feature.
The WildStorm feature has the potential to transform a maximum of five reels Wild.
Wild Reels pay out as separate symbols.
During WildStorm, the Scatter collector is re-filled if you don't complete a win.
You will not be able to re-trigger Svartalfheim Free Spins.
During this feature, bets are exactly the same as on the spin that activated it.
Any wins you achieve during Free Spins are paid in addition to wins from the base game.
Wild Lightning Feature
While playing Free Spins, if a Wild symbol is displayed on reels 2, 3 and 4 then you will activate the Wild Lightning feature.
The symbol position that the triggering Wild symbol landed on is activated, and when another Wild appears in that spot the reel becomes Wild for that spin.
The charged location is removed as soon as the Wild Reel is activated.
It's possible that when you start Free Spins, random symbol positions could be activated in advance.
Up to one, two or three activated positions are available in the Vanaheim, Alfheim, and Nidavellir Free Spins features respectively.
Wild Reels pay out as separate symbols.
You cannot initiate this feature during Svartalfheim Free Spins.
