Thunderstruck II online slot review
In this Casino Ideal review, Evan Carrington describes Thunderstruck II as Microgaming’s follow-up to the popular Thunderstruck slot. It adds updated graphics, features and a more developed storyline, with appeal for fans of the original and players interested in Norse mythology.
Theme and Story Line
The game is set in Asgard, the ancient city, and draws on Norse mythology and the god Thor. Its four central characters are Thor, Odin, Valkyrie and Loki. They can help you win up to four times your bet or unlock up to 25 free spins.
Graphics, Sounds and Animations
The reels pair playing-card-style symbols with familiar images from the original game, including Thor’s hammer. Storm sound effects bring lightning and thunder into the experience, while winning spins show and sound like a stack of coins falling. Dramatic background music adds intensity and suspense.
Thunderstruck II also features dark clouds moving over the reels and characters leaping out as the reels spin. These animations are especially likely when the Wildstorm feature is triggered.
Top casinos to play Thunderstruck II:
Gameplay
Start by choosing how many coins to wager on each line. The “bet max” button at the bottom of the screen sets the maximum wager, while “spin” in the lower right-hand corner starts the reels. Alternatively, select autoplay to spin automatically five or ten times. After each spin, check the box in the lower-left-hand corner to see your credits.
Bonuses and Free Spins
The Thunderstruck II symbol acts as a wild, and the Wildstorm feature can also appear at random, turning up to five reels wild at once. The slot’s best-known feature is the Great Hall of Spins, which you reach by landing three or more Mjolnir or scatter symbols. The character you unlock determines the additional feature:
- Valkyrie—awards ten free spins and multiplies your winnings by 5x. The free spins feature may retrigger.
- Loki—unlocks the Wild Magic feature. When the Wild Magic symbol appears on the third reel, other symbols are randomly changed into substitutes. Loki also awards 15 additional spins.
- Odin—awards 20 free spins and unlocks the Wild Raven feature. Wild Raven can randomly turn selected symbols into 2x or 3x multipliers. Land two ravens and your winnings increase 6x.
- Thor—awards 25 free spins and unlocks the Rolling Reels feature. Rolling Reels can produce consecutive wins, with a winnings multiplier of up to 5x.
Bet Sizes, RTP and Variance
Wagers range from one to ten coins per line, and the potential jackpot is up to 6,000 coins. The slot is generally considered medium variance, so there may be short periods without a win. The review’s stated trade-off is that wins may be larger than in games with more frequent wins. Thunderstruck II has a Return to Player of 96.65%, roughly average for Microgaming Slots: Features, RTP and Jackpot Games.
Conclusion
Microgaming builds on an already popular slot with new features and more ways to win, retaining appeal for fans of the original Thunderstruck and potentially attracting new players. Despite the changes, some players consider Thunderstruck II’s graphics and symbols fairly basic, while appreciating Microgaming’s additions to the original. The review listed the game at casinos it described as reputable online casinos, including Gate 777, SlotsMillion, Jackpot City Casino, and CasinoChan.
