100 Spins Test

This 100 Spins will be updated by Steve Madgwick 

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

Game Data

Collected by Andrej Trajkovski


Xterminate has a futuristic feel. Protests are taking place on the streets, and things are being set on fire. Anarchy is the order of the day, and there are plenty of anarchist symbols on the reels. We're not told what the people are protesting against, but it looks VERY important.

In addition to the Xterminate Multiplier feature mentioned in the summary, there's also the Charged Wild symbol. This symbol has a random number of lives from 1 to 3. One life is consumed when a wild is involved in a win, and when all lives are consumed, the Charged Wild disappears from the grid.

Key Features

Written by Slots Content Manager Jenny Mason

The grid is industrial; you can see pipes and barbed wire on the steel-coloured reels. The symbols have been designed in neon shades which are a dramatic contrast against the grid. The character symbols are a robot head, gas mask, spiked club, and a graffiti can. These are then followed by the A, K, Q, J and 10. The Ace is designed to be an anarchist symbol.


The Xterminate slot game is made up of 6 reels and 5 rows to play with. 


Xterminate is a scatter pays game, so if you land 8 or more symbols of the same kind anywhere on the grid, it triggers a win.  


Return to Player, more commonly referred to as RTP, is a way of measuring (theoretically) what percentage of players' stakes will be returned to them over the long term, so it's one to look out for. The higher the number, the better for players; RTP should be around 96% or more. Xterminate is much lower than the average, at only 94.12%.

Thunderkick uses this RTP figure as a default value, so if you shop around, you’ll discover different rates, though in this case, they are 94.12% or lower. We’ve identified a few RTPs at some of the current popular UK online casinos and added them to the table below.

It's worth noting that RTP is just one factor when deciding which site to play at. You should also consider payment options, a list of games, customer support, and welcome bonuses and deals. Our casino reviews look at this information and much, much more.

Stake Range

The Xterminate slot game has a wide bet range, starting at £0.10 and going up to £100.

Max Win

The max win for the Xterminate slot game is 25,000x your stake.

Wild Symbol

The Wild symbol for the Xterminate game is depicted by the Charged Wild symbol, which you can see in the screenshot below. It substitutes for all other symbols apart from the Bomb symbol. It's worth a random number of lives from 1 to 3. One life is consumed when a wild is involved in a win and when all lives are consumed, the Charged Wild disappears from the reels. Charged Wild symbols are protected when a Bomb explodes.


Play Experience & First Impressions

There is no bonus round for the Xterminate game, which was a surprise, so there are no free spins to enjoy. All of the action takes place during the base game. But isn't the bonus round usually where the magic happens? I tried to keep an open mind but the game felt a bit flat without it. There was not enough in the base game to make it exciting enough to warrant not having a bonus game. When the Xterminate Multipliers trigger, this is fantastic, they look superb on the grid, and it is often triggered when testing the game for this review. But it felt like the game needed a bit more meat on the bones.

The other headliner feature is the Bomb symbol, which, again, when triggered, does look superb visually (see the above screenshot). Here when it's visible with winning combos, it explodes but does not detonate all instances of the most common symbol in view. If more than one symbol is equally common, only the highest-paying one is held. All other symbols are removed, triggering an Avalanche of the reels. This can bring in wins if it's a decent symbol.

Expert Verdict

A presumption has been made that this game is set in some kind of end-of-world scenario, although Thunderkick doesn't specify this. Maybe AI has finally taken over the world like we've been told it will? Staying with the theme of robots, when I first saw the game name, I  had the word 'exterminate' in a Dalek voice on repeat in my brain. But this is probably a British reference AND a British reaction. However, the game has nothing to do with a certain popular British TV series.

When you start playing, a warning message pops up on your screen saying, "High velocity! Brace yourself. This game isn't for the light-hearted" So even though the max win is a decent amount at 25,000x, it probably won't be triggered that often due to having such high volatility. Incidentally, Xtermimate is the 5th best max win amount, well, in fact, it's in joint 5th place with Lost City of Djinnm, Baron Bloodmore and Bones & Bounty  We've listed all of the Swedish studio's games and written about the best Thunderkick slots if you want to find out more.

This is a cool-looking slot, very modern, with zingy neon colours. The dystopian futuristic theme is certainly original, it almost has a Terminator feel to it. I was half expecting Sarah Connor to step out of the shadows.

The RTP is hugely disappointing, though, and it's difficult to look past this, it is one of the lowest we've seen in a while, and it's the lowest of all of Thudnerkick's 60-slot games, which isn't a great title to hold.

The last Thunderkick slot game we reviewed was 12 Bolts of Thunder. which we liked but didn't love, which in a nutshell, is how we feel about Xterminated.
