Casino slot game Thunderstruck by Microgaming for free

Casino slots game Thunderstruck by Microgaming for free
Long before the successful 3-logy of Marvel Studios: Thor (2011); The Dark World (2013), and Ragnarok (2017), the Nordic God of strength and humanity's protection had appeared in numerous works of art and references to him had cropped up quite frequently in contemporary pop culture. One of those noteworthy, exciting tributes inspired by the thunder deity is Microgaming's legendary Thunderstruck slot machine (2004).

It is a Medium Volatility classic machine with a theoretical RTP of 96.10%. Other technical aspects of the game are the 5x3 playing field, 9 pay lines, and a maximum payout of 150 000 coins. It offers simple gameplay, and even though it is short on bombastic features (the only extra here is the bonus Free Spins), it carries its weight as one of the most famous titles in Microgaming’s collection for over 17 years and become the source of plural remakes.

Personal testers’ opinion

  • Despite being a veteran slot (after a mobile-friendly facelift in 2008), Thunderstruck is still super popular at many casinos' lobbies, so in light of the constant prize pool accumulations, players can profit regularly, as they can catch the slot customarily in a ‘hot’ mood. One reason for the endless fame of the game is the bottom bet size possibility of just 0.09 cents per spin, which makes it very suitable for the low-rollers. OK, testing the Thunderstruck, even though it looks, sounds and feels basic, is still acceptable, as we rely on the Slot exigency Nr.1: to be profitable.
  • The hit probability here is around 30% (a tolerable number). On the other hand, the Free Spins are launched with acceptable frequency (statistically once in 149 spins), but what is remarkable here is the generous paytable:
  • 5OAK - Thor (Wild) - 1111.11x the total bet
    5OAK - Rams (Scatters) - 500x the total bet
    5OAK - Hammer & Thor’s hand - 83.33x the total bet
    5OAK - Castle - 44.44x the total bet
    5OAK - Lightning & Horn- 27.78x the total bet
    5OAK - A & K - 13.89x the total bet
    5OAK - Q/J/10/9 - 11.11x the total bet
    Whereby 9’s and Scatters have value also for 2OAK.

During testing, of course, we didn’t hit the declared maximum win, but we still booked a quite good win of 296x the total bet once, while our average stats for the bonus results come to just 36x the total bet. Moreover, the Thunderstruck slot machine is not the best choice for fulfilling the bonus requirements: wagering index registered here - 5.51 (out of 10), so we can only leave a neutral recommendation for the bonus hunters. Regarding games with real money, we strongly advise sufficient starting balance (of at least 200 bets) and wait for the Free Spins, where the theoretical RTP increases to 97%.

  • Microgaming has never disclosed out loud the full potential of this 9 win ways old-timer, but considering the numbers published for the reskins of Thunderstruck, we see 3333x the total bet (or 150 000 coins) is the highest prospect of the game. However, the slot is theoretically capable of much more (for a full grid of Wilds: 9 x 1111=9999x the total bet; in the ultimate lucky situation, during the Free Spins where the wins are tripled, this translates as 30 000x the total bet). All this brings us to a conclusion: the max potential is capped by the developer at 3333x - a fraction of the hypothetical scope.
  • So, some jokes and rude comments are circling regarding the obsolete graphics of the slot. Still, with its solid potential, which is practically realized (we’ve seen on some snapshots), the old game deserves grandiose respect rather than belittling. In fact, the slot is built with such a powerful math model that the developer milked it numerous times, hoping via reskin games to achieve the same widespread popularity. Just check the Adventure Palace slot (2004), Ladies Nite slot (2004), Karaoke Party slot (2016), Festive Indulgence slot (2019), Arctic Magic slot (2019).
  • Also to fame rose the released in 2010 sequel Thunderstruck 2 slot machine, built with 243 win ways and 8000x the total bet maximum payout outlook.
