Thunderstruck slot review (Microgaming)

thunderstruck slot review Microgaming

Thunderstruck was one of the first online slots that showed online gamblers worldwide that you do not need to visit a brick and mortar casino to have fun gambling. Thunderstruck was released by Microgaming in 2004 when online casinos were still in their infancy. Netent was just slowly starting to establish themselves. The big slot developers such as WMS, IGT, and Aristocrat focused a full 100 per cent on the (then) more lucrative offline gaming market.

Thunderstruck is to slot machines what the Rolling Stones are to classic rock music: a timeless classic that never grows old

Microgaming took full advantage of the immense opportunities that were almost laid out before them and released some classic and hugely popular slots. The rest is, as they say, history.

Thunderstruck was by far their most successful online slot. It has (the then standard) 9 win lines, a traditional free spins bonus and a detailed and nicely designed Nordic Mythology theme.

You can still find Thunderstruck in the top 10 list of most-played Microgaming slots of every Microgaming casino.

No small feat, but not entirely unexpected, as Thunderstruck still has a lot going for it. It has an excellent return to player of 96.0% and demonstrates a perfect balance of winning, excitement and fun.

With the right ingredients, a slot does not need hundreds of pay lines — high tech animations and intricate storylines. Thunderstruck is simple, cool and kick ass.

Thunderstruck slot features and gameplay

The number of win lines can be manually adjusted at Thunderstruck. The minimum number of pay lines is 1, and the maximum is 9. Most players will always play the maximum number of pay lines, something that we recommend as well.

Then, by choosing your coin value and the number of coins you want to stake, the amount per spin is determined. The minimum bet per spin is $0.01; the maximum bet is $45 per spin.

The Nordic Mythology theme shines through in the symbols – lightning bolts, Thor’s hammer and the horn are some of the symbols, next to the traditional 9, 10, B, J, Q, K and A symbols.

The Thor symbol is Wild and doubles all winnings. Due to the low number of pay lines and the medium variance of this slot, 5 of a kind payouts are generally high, especially when the 2x wild multiplier comes into play.

Thunderstruck bonus feature

When three or more scattered Ram symbols appear, you have won 15 free spins at a 3x multiplier. Free spins can be retriggered during the bonus game, giving you extra credits (up to 1,500 x your bet) and even more free spins.

The free spins bonus feature, although simple and straightforward, offers a lot of excitement – a super big win is waiting around the corner with every free spin, and huge wins have been documented.

Our verdict on the Thunderstruck slot

Thunderstruck is an older online slot without too many bells and whistles but is tremendously enjoyable.

Graphically and technically it might be showing its age a bit but don’t let that put you off – Thunderstruck is still one of the best online slots around, pleasing both new and experienced slot players.

3.5 out of 5 stars.
