Thunderstruck Game Overview

Brought to you by Microgaming, Thunderstruck slots is the first in the ever-popular series about the Nordic thunder god: Thor! The overall design strongly reinforces this theme with symbols like Thor’s Castles, his Hammer, his Fist, and even Thor himself! The theme is exciting and even if you really aren’t concerned about that, this is one of those really well-rounded slots games that appeals to all kinds of players - including those with a tight budget. In the review that follows, we will look the specific points of the game that make it unique and, once you are done reading, you will know everything necessary to play Thunderstruck online slots for the first time!

The Thunderstruck slot machine uses one of Microgaming’s standard layouts; it has five reels and nine paylines. This low number of paylines may bother high rollers who want the action of as many as fifty paylines, but lower limit players will be happy to know that they can play Thunderstruck slots on a budget. With a limit of five coins per line and coins from one cent to one quid, you can play this game for just £0.09 per spin or choose to wager as much as £45.00!

Review of Thunderstruck's Key Features

Multiplying your underlying bet by the appropriate multiplier: 2x, 5x, 20x, or 500x

Thor is, naturally, the wild symbol in Thunderstruck slots. This symbol can act as any other symbol, other than the Ram, when doing so helps you get a winning combination, or a better winning combination, along an active payline. Any wins that are made possible due to this feature are also doubled, to make the deal that much sweeter!

The scatter in Thunderstruck online slots is the Ram symbol. With this feature, you can forget about the paylines: just get these symbols to appear anywhere on the screen at once. With as few as two Ram symbols, you will receive a scatter payout, and the more you see, the more you win! For two to five of these symbols, the respective payouts are calculated by multiplying your underlying bet by the appropriate multiplier: 2x, 5x, 20x, or 500x! This can be worth up to 22,500 coins for max bettors!

Stunning graphics and symbols with great payouts

There are many ways to win in Thunderstruck, particularly with the impressive bonus rounds. But the game also features stunning graphics and symbols with great payouts you can see below.

A set of fifteen free spins with a 3x multiplier

The Ram doesn’t just payout in the form of a scatter win: it is also the only bonus symbol in the game. For three or more Rams appearing at once on your screen, you will automatically be taken into the bonus mode. This is a set of fifteen free spins with a 3x multiplier that applies to all wins earned during this round! Remember, this is always awarded in conjunction with your 5x-500x scatter payout!

A bonus game with the chance to double or even quadruple your winnings from the preceding round!

Every time that you have a winning spin, you will be able to take advantage of the final feature that this game has to offer: a bonus game with the chance to double or even quadruple your winnings from the preceding round! You will see a downward facing playing card and you can choose to guess its color (for double or nothing) or its suit (for quadruple or nothing). Of course, if you guess incorrectly, you lose all of your winnings from that spin. Luckily, this game is totally optional; if you want to take your money and walk away, that’s fine as well.

Players love what Thunderstruck has to offer

Thunderstruck is the first game in a now super successful Microgaming franchise. It is a major draw for many online casinos and with good reason. Thanks to fun design, great bonuses, wilds and frequent payouts, players love what Thunderstruck has to offer, and continue to play it in 2023, despite the release of a sequel.
