Thunderstruck II

Once the Thunderstruck II slot has loaded, players may be somewhat underwhelmed initially. The theme is rather basic, with the board set on a slab of granite and traditional sound effects playing for various outcomes.

The range of bonus features sets this title apart from the rest, of which there are a few to discuss. Interestingly, these modes are progressive, too, meaning that players can be awarded with different bonuses, depending on how many have been triggered previously.

This title was created by Microgaming, one of the largest companies in the online slots space. Since the company was formed in 1994, they have built an impressive portfolio of games, including the likes of Bar Bar Black Sheep, Lucky Zodiac, and Oink Country Love.

Microgaming is seemingly fond of releasing casino slots that appear to be retro, while simultaneously including a handful of intriguing features.

Game Features

The standard 9, 10, J, Q, K, and A icons all make an appearance in Thunderstruck II, with each symbol seemingly being carved out of stone. Next up is a boat, the Bifrost Bridge, a Valkyrie, Loki, Odin, and Thor. If five Thor icons form a matching combination, players will be awarded with over 16x their stake size!

Scatter icons can also be found in this title, shown as a Mjolnir, with the ability to trigger the main bonus mode. There are also two variations of wild, a standard and a magic variation. However, the latter only appears in one of the bonus rounds. Like in other slots online, the wilds in Thunderstruck II can replace any standard or premium icon or form a combination on their own.

The first bonus feature in Thunderstruck II comes in the form of a spin modifier that can activate randomly during any spin.

If it triggers, Thor will appear on the board and turn 1, 2, 3, 4, or 5 reels wild, before any combinations are calculated. Should all five reels become wild, players will be awarded with the maximum potential win for this release, sitting at 8,100x the stake size.

Now, the main bonus mode can be triggered when three or more Mjolnir scatter icons appear simultaneously. Players will start with the Valkyrie bonus, which will award ten free spins with a multiplier of 5x being applied to all matching combinations. After the bonus has been triggered 5, 10, and 15 times, the Loki, Odin, and Thor bonuses will become available in that order.

The Loki bonus will award 15 free spins and introduce the ‘Wild Magic‘ mechanic. If the corresponding ‘Wild Magic’ symbol appears on reel 3, random positions on the board will be turned into wilds, too.

The Odin mode awards 20 free spins and activates the ‘Wild Raven‘ feature, meaning that ravens can randomly fly across the board and add 2x or 3x multipliers on top of certain symbols. Both of them can also select the same position, adding a 6x multiplier to the associated icon.

Last but not least is the Thor bonus, awarding 25 free spins with the ‘Rolling Reels‘ mechanic. This means that any matching combinations will be removed from the board so that new symbols can drop in from above.

With each cascade, the win multiplier will increase by 1x, up to a maximum of 5x. However, this is not a progressive multiplier and will reset between spins.

Pros

  • Variety of different bonuses
  • Fresh features added over time
  • Maximum potential winnings sit at 8,100x the bet

Cons

  • Very limited appearance
  • Sound effects could also be improved

FAQ

If the bonus gets triggered a total of 5 times, the next bonus mode will become available. This is repeated at 10 and 15 triggers, too. 

The minimum stake size in this title sits at 0.30. 

No, the free spins bonus mode in Thunderstruck II cannot be bought. 

When compared to other online slots, this release has low volatility.
