Award-Winning Mythological Translation

Thunderstruck is one of the original Microgaming productions and has remained at the top of the player preferred list since 2003. By today's standards, it's not as high-tech or advanced, but the recognizable theme and the booming presence of Thor's wild card magic have lured in slot lovers around the world.

Microgaming is a multi-award winning software company with accolades like "Best Software Provider" in 2010 and 2016 "Innovator of the Year." It's responsible for the first internet casino and has numerous titles in its catalog, but Thunderstruck remains as one of the most well-known.

In 2003, the game was widely referred to as "This Year's Slot Machine," and it also has the designation of being the first iPhone slot game.

The Power Of Thor Unleashes The Grand Prize

It's a bit surprising that with all of the bells and whistles available on the newest of video slots, that a game like this stays at the top of its game, but slot players seem to enjoy the simplicity and the familiarity that it provides.

If you've ever played Cleopatra, you'll note that it has a very similar format. There is a top payout potential of 10,000 credits, and there is only one bonus round. So, whereas you have newer games with random jackpots and mini, minor, and major prize levels, and all kinds of different video introductions and extended bonus play, Thunderstruck is much less complex.

What you'll want to root for when playing:

Thor: This is the biggie. If you get five Thor symbols, you claim the top prize of 10,000 credits. Thor also acts as a wild card and can replace any symbol except the Scatter Ram.

Scatter Ram: Another dual purpose symbol, if you receive three, four, or five scatter rams, you start your bonus round with 15 free spins. But, in the famous words of all infomercials, "That's not all…" at least two scatter rams provide a payout of its own. Two provides for two additional credits, three of them provides five, four equals 20, but five of these symbols kick starts your bonus round with a 500 credit win before your first free spin even starts.

You've got other symbols like Thor's hammer that offers up a 750 credit win when five of them appear on a pay line. Struck by lightning five times? That's another 250 for you.

The Gamble Feature

You probably already thought you were gambling when you're playing Thunderstruck, but the game offers you a gamble on gamble option. If you're looking for bigger wins, the Gamble button might just do the trick. After you have a successful round, you can click that button, and a deck of card appears on your screen.

From here, you get to make an additional bet on the suit or the color of the card. If you have guessed the right color, your prize then doubles. If you guess the right suit and win, you get four times your original payout. You don't want to be incorrect though, or you lost the winnings entirely, and no one wants that.

Scattering Rams

Rams are desirable as they will kick start the only bonus round available in this game. As we mentioned previously, the Rams pay out some prize level starting at two in a line and also three or more trigger 15 free spins.

The spins pay out at three times the regular prize amounts and can be retriggered by getting the scatters again during bonus play.

It Strikes Again

Let's talk about Thunderstruck II, the sequel and the game that many people like even more than the original. It launched 2010, and it was created in HTML5 as well as at a 1024 x 768 resolution, so the quality is going to be much better. When you put the two versions side by side, the original looks quite dated even though most people don't seem to care.

Whereas the first game kept a fundamental premise, the follow-up is a five-reel, 243 ways to win game with four different bonus rounds and the multipliers range from two to six times.

Three or more of Thor's hammers will unlock one of the chambers of Valkyrie, Loki, Odin, or Thor and each chamber offers a different bonus game.

Valkyrie: ten retriggering free spins plus a five-times multiplier.
Loki: 15 free spins and a wild magic feature that transforms symbols into additional wild cards.
Odin: 20 free spins with two, three, or six times multipliers.
Thor: 25 free spins and a rolling reels feature up to a five times multiplier.

The Gods Remember

A unique feature of this version is "Paytable Achievements," or in layman's terms, the saving of players' past wins that will help them in future pursuits of different game rewards. Players can achieve Gold Status and maybe even Gold Status in the Great Hall of Spins.

The Treasure Is More Substantial

Thunderstruck II offers a higher payout potential that won't come easily but, if everything falls into place with free spins and the maximum payouts you could receive, there are 2.5 million coins that could be yours. Remember, this isn't a progressive jackpot game either so everything has to line up correctly to receive that amazing prize.

Your Fate Is In Your Hands

With both versions of this favorite game, your decision regarding how much to risk ultimately decides what you're able to, hopefully, receive in a reward. The higher you bet, the higher the credits will go if you get big wins that are accompanied by multipliers or if your free spins are retriggered over and again, you should be able to watch those numbers rise higher and higher.
