12 Bolts of Thunder Slot Machine

Thunderkick made this a slot with 5x4 reels and 20 paylines. The 12 Bolts of Thunder inspiration seems to have come from the Scandinavian deities, with Thor’s Hammer being one of the main symbols you’re going to get inside.

Instead of a bleak landscape, the developer has opted for a colourful slot game. The symbols are painted in bright colours and include well-known elements from Norse mythologies. Those include the already mentioned hammer, a door/portal to Asgard, a horseshoe, and a few vintage slot symbols such as bells and BARs.

Eight basic-paying symbols and three special icons complete this video slot. Notably, all the symbols are crafted colourfully to elevate the game’s immersive design. Wins are completed when 3+ of a kind appear sequentially from the leftmost column to the right without gaps.

However, stay hopeful for the substituting Wilds (W) as they may help complete the regular winning sequences. Further, the game has Hammer and Double Door bonus scatters for the extra game features.
