When a Thunderball symbol appears during the main game, it can either be blue or gold.

New Thunderball symbols are also locked in place for the remaining spins.
The number of spins remaining will reset to three every time a new Thunderball symbol lands.
Extra rows are unlocked when certain numbers of Thunderball symbols land.
Row five, six, seven and eight are unlocked sequentially when 15, 20, 25 and 30 Thunderball symbols land, respectively.
The feature ends when no spins are left to play or if all positions on the reels are filled.

Free Spins Bonus
There are five modes of free spins in this game: Jotenheim Free Spins, Vanaheim Free Spins, Alfheim Free Spins, Nidavellir Free Spins and Svartalfheim Free Spins.
Each mode offers a different number of free spins and Wild multiplier value.
|Mode||Number of Free Spins Triggers||Number of Free Spins Awarded||Wild Multiplier Value|

The Svartalfheim mode is unlocked when 20 pairs of Scatter symbols appear during the main game.
This mode will then play when the next Free Spins Selection is triggered.
The Svartalfheim Free Spins Bonus awards one free spin with the WildStorm feature.
This feature transforms up to five reels into Wild reels, which pay as separate symbols.
When only two Scatter symbols land on a spin, they are added to the Scatter symbol collector.
If no win is achieved during the WildStorm feature, then the Scatter symbol collector is refilled.
The collector will reset at the end of the WildStorm feature.
Landing three or more Scatter symbols will re-trigger the number of free spins initially awarded.
It is not possible to re-trigger the Svartalfheim Free Spins Bonus.
If multiple Wild symbols substitute in a win, there is no additive or multiplicative effect.
All modes use the same bet level as the triggering spin.
Any wins achieved during free spins are added to main game wins.
Wild Lightning Feature
This feature is triggered when a Wild symbol appears on reels two to four during the Free Spins Bonus.
Triggering Wild symbols will activate the position that they land on.
Reels become Wild for that spin when another Wild symbol lands on the same position.
The Wild reel is only active for the triggering spin and pays as separate symbols.
The active position is removed when a Wild reel is awarded.
At the beginning of a Free Spins Bonus, it is possible that random positions may already be activated.
One, two or three positions may be active at the beginning of the Vanaheim, Alfheim and Nidavellir Free Spins Bonus, respectively.
The Wild Lightning feature cannot be triggered in the Svartalfheim Free Spins Bonus.
