Overview

This game is available at the slot sites listed above, and let me tell you, it's an out-of-this-world experience! Thunderkick Games nailed it with an alien-themed 5x5 slot that banishes boredom to a galaxy far, far away. The Expanding Multiplier Wilds and Bonus Invasion are just the start—imagine rockets of multipliers up to x5 and Free Spins raining down like a meteor shower. 

Every spin feels like a step into the unknown, with symbols transforming under the watchful eyes of extraterrestrials, boosting my chances of astronomic wins. Truly, slot games have never felt this electrifying or filled with endless possibilities!

100 Spins Test

This 100 Spin test was updated by Steve Madgwick on 13/09/2023 

100 spins is not a Real Test

We give every slot a 100 spin test to see just what it can do, or not as the case can often be - 100 spins is no reflection of the likelihood of any other 100-spin session, as RTP's are set over many millions and probably billions of spins. So this 100 spin test is just for entertainment and insight purposes

Test Comments

The 100 spins test for this new game from Thunderkick went quite well - Indeed and above theoretical RTP session is always good ans this delivered with a session return of 116.9x, all thanks to a really good average winning spin value of over 5x, despite just 23 winning spins and no bonus round landed, 

The biggest base game win was an impressive 36x, but was accompanied with several more good value wins including a 25.6x a 10x and several 7x wins too - a return of 116.90x across 100 spins without a bonus is very nice.

Graphics, Music, and Sound Effects

The sound effects and accompanying music are not distracting and fit well with the theme - The visuals are sharp and colourful and the important premium symbols pop out as they should making wins instantly identifiable.

There is quite a cool bonus scatter symbol in the form of an animated TV and in fact, all symbol animation is complementary rather than confusing

Key Features

So let's get into the nuts and bolts of this game and see what each element really has to offer in terms of entertainment and features

At OLBG we write slot games reviews that include accurate info about a game’s essential features such as paylines, reels, bet range and bonuses. Stay put if you’d like to read about my first impressions and expert verdict. 

Theme – Space and Alien Invasion

While sometimes a theme can be a tenous thing with a slot game with only passing reference to the supposed subject there is no doubt that with ZAP Attack and the log of a flying Saucer, this game is about space and Aliens and they appear in abundance in the game symbols and features

Reels

Zap Attack a lot is played on a 5x5 board set up and for simplicity there are no expanding reels, addition columns or anything. It remains 5x5 throughout the base game and the bonus game too

Paylines

There are 25 win lines in the base game, and this figure is retained for the bonus game. Again, a simple pay line premise and it works wonderfuly

RTP

Skip this section if you’re a seasoned slot player. But it’s always worth including an explanation of RTP in a slot game review. You’ve probably seen Return To Player referred to as RTP on slot sites. This is a way of measuring what percentage of stakes will be returned to players over the long run. The number is usually somewhere between 94% and 96%. 

The RTP range can often vary depending on which UK online casinos you play, but the Zap Attack slot RTP comes in at an above-average 96.15% which is pleasing to see from Thuderkick

When deciding which sites to play at there’s more than RTP to think about. Factors such as payment options, game library, customer support, welcome bonuses and deals and mobile optimisations are also important. Our casino reviews analyse these factors for you.

Nowadays most players enjoy trying more than one game. Because of this, we decided to create a page with the slot sites we recommend. If you’re a UK player you can launch one of these titles straight away, there are literally hundreds to choose from. 

Stake Range

A nice minimum stake of £0.10 per spins which increases to a below average £100 

Max Win

A little lower than normal 5,000x max win is available on this game. Certainly, Thurderkick have put out bigger max win games in the last, but still 5,000x stake is not a bad return if you should be so lucky as to land it. 

Wild SYmbols

The flying saucer spacecraft is the Wild symbol in Zap Attack, but you you two possibilities - There is a standard stand-alone wild which replaces any other symbol to make winning lines, but the better one, is the expanding, 'Invading Wild', which, if landing and assisting with a winning line, will expand to cover the entire reel, very handy as it also has the possibility of landing a multiplier to those wins too up to 5x

Free Spins

Landing three bonus TV symbols will gain you 7 free spins, although you can land, 4 or 5 as well, with a max of 15 free spins to be won.

The free spins round begins with the four premium symbol characters on the right of the screen, the idea is for these to be shot and transformed into aliens to be replaced in the bonus game. The way this happens is if an Alien should land on a spin, if he has a laser gun he takes one pot shot at the premium. Each of the four premium symbols can be transformed into more Aliens on the reel offering more winning chances for the most valuable symbol, or indeed, further aliens with more ray guns to transform more Humans.

Each time a human is transformed, an extra free spin is awarded, all the time, increasing aliens on the play board which can also land with invading wild multipliers

Jackpot

There are no specific jackpots with this game. If you’re interested in games with jackpots you should visit our page with the best jackpot slot games.

Play Experience & First Impressions

My first impression was good visual elements, a nice soundtrack and sound effects. Play is quick enough, and there can be periods of dead spins, but winning spins are generally above stake which is a nice change to many games these days. I liked the game instantly, and the bonus game is a decent concept, although not entirely unique. I played the 100 spin test and it was a good experience, above theoretical RTP which is always nice, althogubh if I am entirely honest, it didn't leave me desperate to come back for more, although its certainly not a game that I would dismiss and never play again - I liked it, is the best I can come up with.

Expert Verdict

Zap Attack from Thurderkick is a good game from a reliable studio, with whom you know you will generally be playing a high volatility slot and should be ready for dead spins sessions but a good base game wins. Zap Atack delivers on all fronts with a good sound track and theme, not overly complicated bonus round mechanic but visually entertaining always leaving that potential at your fingertips to keep you playing.

In a world of multiple weekly slot releases, Thunderkick refuse to rush titles out, and this is apparent in the fact that each comes with a unique look, feel and play experience.
