- Max win: 8000x
- Reels: 5
- Paylines: 243

Thunderstruck 2 Main Features
The theme of Norse mythology has become a very familiar one in slot games, and thanks to some rather famous superhero movies the characters of Odin, Valkyrie, Thor and Loki are now practically household names. Even so, Thunderstruck 2 is still arguably one of the best examples of this slot genre to be found. Symbols include the aforementioned deities, a Viking warship, and the legendary city of Asgard with the rainbow bridge known as the Bifröst. The orchestral soundtrack is suitably epic, but never intrudes on the gameplay.
Layout, Bet Limits & Payouts
The 5×3 layout gives players 243 ways to win with all paylines always active. Stakes can be set between thirty pence and £15 per spin, with the maximum win at 8000x the stake. When playing at max bet, the largest payout is therefore £120,000. This kind of game mechanic has become quite common, so it is easy to forget that it was Microgaming that introduced the massively increased winways. Quite a revolution at the time.
Thunderstruck 2 keeps the action coming with plenty of special symbols and bonus features. There are wilds, multipliers, and a progressively rewarding free spins round. Bonus features are covered in more detail in a moment.
Thunderstruck 2 RTP and Variance
The Thunderstruck 2 slot RTP is slightly above average at 96.65%, which equates to a house edge of 3.35%. This number is theoretical, and means that over time and including all players, the casino site hosting the game can expect to take 3.35% of all cash staked on the slot. In reality, the RTP is just a guideline and doesn’t predict what individual outcomes will be over shorter time periods.
The variance of the Thunderstruck 2 slot is listed as medium, meaning that payouts come fairly steadily. The combination of RTP and variance – also known as volatility – mean that this game shouldn’t deplete your bankroll too rapidly. There are still some bigger wins to be had thanks to free spins and other special features.
Thunderstruck 2 Special Symbols
There are twelve paying base symbols and two special symbols in the Thunderstruck 2 slot. The lower paying ones are playing cards, which have been drawn to stay within the game’s theme. Picture symbols include the gods and Asgard, and there is also a bonus and scatter in the mix. The scatter is represented by Thor’s hammer. Wilds are portrayed by the Thunderstruck 2 logo and substitute for all symbols except the scatter, and give players a boost when they do. If one or more wilds is part of the winning combo, it pays out double what it would with regular symbols. A look at the paytable reveals the following payouts, based on the minimum spin value of £0.30:
Thunderstruck 2 Symbol Paytable
| Symbol | 2x | 3x | 4x | 5x |
|---|---|---|---|---|
| 9, 10 | – | 0.05 | 0.10 | 1.00 |
| Jack, Queen | – | 0.07 | 0.15 | 1.25 |
| King, Ace | – | 0.10 | 0.20 | 1.50 |
| Viking ship | – | 0.15 | 0.60 | 2.50 |
| Asgard | – | 0.15 | 0.60 | 3.00 |
| Valkyrie | – | 0.20 | 0.80 | 3.50 |
| Loki | – | 0.20 | 0.80 | 4.00 |
| Odin | – | 0.30 | 1.00 | 4.50 |
| Thor | – | 0.30 | 1.00 | 5.00 |
| Scatter | 0.30 | 0.60 | 6.00 | 60.00 |
| Wild | – | 0.75 | 2.00 | 10.00 |
Thunderstruck 2 Slot Bonuses
As we have just seen, any wild gives an automatic 2x win multiplier, but that is just the start of the bonus features to be found in the Thunderstruck 2 slot. The main set of bonuses are the four different free spins rounds, based on each of the four main characters. Landing three or more scatter bonus symbols – the mighty Hammer of Thor – triggers the free spins rounds. As the game progresses, the next free spins game is unlocked. As well as this, there is a randomly activated Wildstorm feature.
Great Hall of Spins Bonus Games
When Thor’s Mjolnir hammer lands on three or more spaces, the free spins fun starts. The longer the session, the further you can progress through the different sub-games in the Great Hall of Spins.
- Valkyrie free spins: After triggering the free spins bonus one to four times, players can access the Valkyrie bonus spins game. This is ten free spins with a 5x multiplier and the possibility to retrigger. In this round, the reels change to a pale pink colour and the music becomes more exhilarating.
- Loki free spins: After landing enough scatters between five and nine times, players can choose the Loki free spins game. Players get fifteen free spins with Wild Magic on the central reel. The reels turn green and spin chaotically, and the music becomes darker and more mischievous. When Wild Magic appears, it shoots a beam of green light at random symbols to turn them wild. Up to four additional respins can also be triggered by landing two or more scatters during this game.
- Odin free spins: From the tenth to the fourteenth triggering of the bonus games, players can select Odin free spins. This round awards twenty free spins with a special feature called Wild Raven. Against a backdrop of a galaxy-filled night sky, Odin’s ravens sit at the top of the reels and randomly fly down to bestow a 2x or 3x multiplier on one of the symbols – 6x if both ravens fly down at the same time.
- Thor free spins: If you manage to trigger the bonus spins for the fifteenth time, then you gain access to the ultimate free spins round – the mighty Thor himself. There are 25 spins in this game, where the reels crackle with lightning and the music gains a touch of electric guitar. Symbols making a winning combo explode and more cascade down to fill their place. As consecutive wins build up, there is a multiplier up to 5x to be had.
Obviously, players need to stick with the game for quite a long time to unlock the successive free spins rounds. However, the Thunderstruck 2 slot has a save function so that players can preserve their progress. Once all four of the bonus games have been unlocked, players can choose which one to use when they get the next free spins round.
Wildstorm Feature
Occurring completely at random, Thor lands on the reels before shooting up to the sky which has become filled with storm clouds. From his position in the heavens, the god of thunder releases bolts of lightning to turn some of the reels completely wild – if you are lucky enough it could be all five reels. If all the reels turn wild, players get the maximum 8000x payout.
Other Features
The free spins bonus rounds are the standout features of the Thunderstruck 2 slot, although the Wildstorm feature can also be quite lucrative if enough reels turn wild. There is not much need for any other special features. Players may notice, however, that with certain combos the phrase ‘achievement unlocked’ appears on the reels. There is no information about this in the paytable, so we thought we would dig a bit deeper to see what this means.
Well, as it turns out, not an awful lot. As you collect ‘achievements’, the symbols in the paytable turn gold one by one. However, aside from an aesthetic change, we could find no material value to unlocking these so-called achievements. A bit of a disappointment, and a missed opportunity to further reward long-term players.
Thunderstruck 2 on Mobile
Like any modern slot worth its salt, Thunderstruck 2 plays equally well no matter what type of device you are using. Anyone with an Android or iOS mobile will be able to play Thunderstruck 2 smoothly and easily. It is, of course, recommended to have a relatively up to date operating system, and a stable connection to the internet.
Conclusions
Thunderstruck 2 slot is still very widely played, despite more than ten years since its release and many other Norse themed games arriving on the market in that time. Playing it for even a short time, it is not hard to see why it has remained so popular. The theme, graphics and soundtrack are all very well considered, and the slot looks and feels just as good as a lot of the games being produced today. The base game may not be overly exciting, but trigger those bonus rounds and it’s a different story. A really fun and potentially very rewarding slot, which more than holds its own against the latest slot releases.
