Xterminate Slot Review

The Xterminate Slot Game

When I first loaded up Xterminate from Thunderkick, the game did not mess about. A warning screen pops up telling you this anarchic slot is not for the faint of heart, and that tone carries through every spin. You are thrown into a dystopian city where protesters, burning streets and neon graffiti sit behind a 6x5 grid using a scatter pays system instead of standard paylines.

Mechanically, Xterminate is all about landing at least 8 matching symbols anywhere on the reels to trigger a win, then watching the Avalanche feature clear them away so fresh icons tumble into view. There is no traditional free spins round, so everything plays out in the base game with Avalanches, an ever-growing Xterminate Multiplier, Bomb symbols and Charged Wilds trying to stitch together those rare but intense win sequences.

Symbols and Payouts in Xterminate

The symbol set in Xterminate fits the protest theme nicely. You get 9 standard symbols plus 2 specials. The lows are the 10, J, Q, K and A card ranks sprayed in graffiti style, worth around 1x to 3x your stake when you land bigger clusters. High-value icons are the spray paint can, spike bat, gas mask and the glowing-eyed robot, which tops the paytable with returns around 4x to 7x the total bet for strong hits.

Payouts use a scatter pays approach rather than fixed lines. Any 8 or more identical regular symbols in view will pay, wherever they land on the 6x5 grid. When a win hits, the contributing icons pay based on your current stake, then disappear in an Avalanche so new symbols can drop in. That cycle is key, as repeated Avalanches are what really feed the Xterminate Multiplier and give this slot its sharp, spiky potential.

Xterminate Slot Bonus Features

Xterminate does not have a detached bonus game, and that may surprise players used to traditional free spins. Instead, your entire session revolves around a cluster of base-game features. First up is the Avalanche mechanic, which kicks in after any scatter win. Winning symbols are stripped from the grid, new ones fall from above, and further wins keep the sequence going until no fresh combination appears, at which point the current run ends and your total payout is calculated.

Hovering above the reels is the Xterminate Multiplier. Every win in an Avalanche chain is first multiplied by the current value, then that win amount is added back into the multiplier itself. It creates a sort of snowball effect where a modest streak can suddenly ramp up into a chunky final value, all applied at the end of the sequence. The trick is getting those long stretches of back-to-back wins before the grid finally bricks.

The Bomb and Charged Wild symbols add more chaos. A Bomb that lands without any win detonates, wiping out all symbols except the most common icon, other Bombs and Charged Wilds, then triggers another Avalanche. Charged Wilds substitute for everything except Bombs and spawn with 1 to 3 lives; each winning involvement burns a life, and the wild vanishes once they are gone. On top of that sits Bet+, letting you pay 2x, 5x or 10x your bet for better hit odds or even a guaranteed win on every spin.

How to Win at Xterminate Slot

Playing Xterminate is straightforward on the surface. You choose your stake, usually between 10p and £100 a spin, and hit the main button or set up Autoplay. The 6x5 grid uses scatter pays, so you are simply hoping to land clusters of 8 or more identical symbols anywhere. In practice, though, success is about stringing enough wins together in one Avalanche chain to crank up that Xterminate Multiplier before the round fizzles out.

Xterminate Slot RTP & Volatility

The numbers behind Xterminate are not particularly gentle. The default RTP is 94.12%, which sits well below the 96% figure many regulars like to see. There are alternate RTP settings at casinos, but they tend to be at this level or lower. Hit frequency hovers around the 10% mark, and the game flashes up a high volatility warning as soon as you load it, which matches my experience of long dry spells punctuated by the odd hectic sequence.

Bet+ tweaks the profile slightly by increasing your chances of landing a win on each spin, and the theoretical RTP nudges upwards on those modes, though it still moves in the mid-94% range. The trade-off is cost, as you are staking 2x, 5x or even 10x your base bet for those improved odds. On paper the slot can reach 25,000x your stake, but given Thunderkick’s track record, I treat that as a distant ceiling rather than a realistic target.

The Final Thoughts on Xterminate

After a decent number of sessions, I am left with mixed feelings about Xterminate. The anarchic theme, gritty soundtrack and oddball multiplier maths make it stand out, and when the Avalanches, Bombs and Charged Wilds line up you can feel that snowballing rush. On the flip side, the low RTP, lack of a proper bonus round and long runs of dead spins made some sessions feel like a slog, almost nudging me towards Bet+ more than I’d like.
