How to play Xterminate mobile slot

Brace yourself! This online slot is not for the faint of heart! You’ve been warned from the first title screen that shows up on this Xterminate slot and you should take it seriously.

The Xterminate slot is a huge 6×6 reel slot created by Thunderkick that is set in a dystopian future where you can win a huge 25,000x your bet, thanks to an insane xTerminate Multiplier where on every avalanching win the multipliers increase and symbols pay anytime there’s 8+ on screen.

There are no free spins, but you do get special symbols. The Bomb symbol removes all instances of the most common symbol, and the charged wild can stay sticky on screen for up to three avalanching wins.

But the most controversial feature is going to be the Bet+, where for 2x, 5x, or 10x your bet, you can buy a totally different game that significantly increases your odds of winning. This is a Thunderkick slot like no other, so let’s repeat the warning: brace yourself.

Xterminate slot has some craze maths in the Multiplier feature

Each win starts a multiplier, with +1. Now, how other video slots would work is that once every win, the multiplier increases by 1 or doubles or multiplies each other. But no. We had to deep dive into the paytable to figure out what was happening because, at first glance, it didn’t make a whole load of sense.

Here’s how the Xterminate Multiplier works: First, the multiplier is multiplied by the current exterminate multiplier, and then the total multiplier is added.

So, let’s say your multiplier is 10x. Then you get a winning combination of x4. You multiply the two numbers together and then add the original multiplier. In other words, 4×10 = 40. 40 + 10 = 50. And just like that, you jump from a 10x multiplier to a 50x multiplier.

Xterminate Bet+ options make or break the game

Xterminate is highly volatile with a low RTP of 94.12%, which is no less than in many equally high-win games at NoLimit City studios. We are used to seeing it from them, but not Thunderkick.

However, it makes the base game difficult to enjoy because you need multiple avalanching wins in a row to get those big multipliers. The wild and bomb symbol help, but this is a long-wait game with the occasional hope of something truly explosive.

That is unless you use the Bet+ button. For 2x your debt, you double your odds of winning, for 5x your bet, you increase your odds of winning by 5x, and for 10x your bet, you are guaranteed a win on every single spin!

Are you willing to place a risky bet?

The minimum bet of this Xterminate slot online is 0.10 a spin. This means that for £€$1 a spin, you can play a game where you are guaranteed a win on every spin. It’s enticing, but you must never forget that you are still only placing a 0.10 bet.

It took us 50 spins on the guaranteed win button to win over £€$1. And that makes sense. This is still a volatile slot, so even if you’re ‘winning’ on every spin, you’re not really winning; you’re just not losing as much. Think Misery Mining or basically ANY Megaways slot machine.

In a world run over by Terminator killer robots, gas mask-wearing thugs holding spiky clubs and spray cans… what do you expect?  An easy ride? Not likely. But that doesn’t make it any less exciting.

We had great fun playing on this Xterminate slot, but you need to be prepared to fight tooth and nail and bet a little more than usual to conquer this world. If not, that’s ok, but you should move on to another dystopia: Cash Truck 2, perhaps?

You’ve been warned, but the very brave will thrive in this unique high variance slot machine.

Xterminate Review Conclusion

The Xterminate slot game is an odd duck. There are no bonus games, free spins, or mini-games. There are just base game spins with ridiculous multipliers and some avalanching wins.

It shouldn't be as much fun as it is. In fact, this is so dangerous we almost feel like we shouldn't give it 5 stars because it's not for everyone. This is a Thunderkick video slot that is for experienced online gamblers only.

But this is refreshing and compelling for those who have been around the casino block a few times. We even love the Bet+ button, which is to be used sparingly but can be used more often than most buy bonus slots.

Don't think too much about the math behind it all; you never thought about the random number generators before, right? Just accept the big multipliers at the top of the reels and enjoy the big wins when they come.
