Annihilator Slot Overview

Annihilator is a heavy metal-themed slot from Play'n GO, built around the Canadian thrash metal band of the same name. It runs on a 5-reel, 4-row grid with just 10 paylines and high volatility. You are basically invited into the Fun Palace, a creepy old mansion from one of the band's most famous tracks, with Jeff Waters himself showing up as the wild symbol.

Bets start at 0.10 and go up to 100, so it suits most budgets. RTP sits at 96.2%, which is slightly above average, and max win is 5,000x. If you have been playing other Play'n GO metal slots like Sabaton or Testament, this one is a bit simpler in presentation but still has a proper old-school charm to it.

Symbols and Paytable

Lower paying symbols are your standard 10, J, Q, K and A royals. Five of a kind with these pays between 2x and 5x your bet. Not thrilling, but they keep things ticking over. Higher up, you have got a haunted mirror, a red guitar and a stone statue, paying 20x to 30x for a full line of five.

Jeff Waters is the wild and can substitute for everything bar the scatter and bonus. A haunted doll acts as the bonus symbol triggering the Fun Palace feature, and the Devil is your scatter for free spins. Honestly, the paytable is nothing earth-shattering. Most of your big hits will come from features rather than base game lines.

Bonus Features

Four features keep things moving here. First is the In Command feature, which triggers randomly. All wilds on screen expand to fill their reels. No win? The expanded wilds stick around and you get a respin with a guaranteed wild landing. This repeats until you get a win, so it always pays out something. Proper decent mechanic that spices up the base game nicely.

Land 3 bonus dolls and you unlock the Fun Palace, a Pick 'Em minigame where you choose dolls to reveal prizes. Find a scatter in there and you trigger the main event: SET THE WORLD ON FIRE Free Spins. You can also trigger those spins directly with 3 scatters.

Free spins start with 8 rounds. An expanded wild is always present and moves left or right each spin, dropping a Trail of Fire on random positions. When a wild lands on a fire position, the entire trail lights up as wilds. That moment can produce some properly big payouts. Extra scatters add 2 more spins, up to 50 bonus spins total.

Volatility, RTP and Max Win

With high volatility and a 96.2% RTP, Annihilator can go through long dry stretches before the features kick in. Max win is capped at 5,000x, which is respectable but not massive by today's standards. Some newer slots in the same metal series offer much higher ceilings. For a relaxed session, I would not mind this cap, but if you are chasing huge numbers this might feel a bit limited.

Ryan Cole’s Verdict

Final Verdict

Annihilator is not going to blow you away with flashy modern graphics or a 50,000x max win, and I reckon the visuals feel a touch simpler compared to other Play'n GO metal slots. But the In Command respins are genuinely satisfying because they always guarantee a payout, and the Trail of Fire mechanic during free spins can light the whole screen up with wilds. That moment alone makes the bonus round worth chasing.

For a casual session, it does the job. Solid RTP, old-school feel, a proper thrash metal soundtrack blasting away in the background. If you like your slots loud and a bit rough around the edges, give the demo a spin and see if it clicks. Just do not expect it to compete with the bigger-budget titles in the same series.

Annihilator FAQ
How does the In Command feature trigger in Annihilator?
It triggers randomly on any base game spin. All wilds on screen expand to cover their full reels, and if there is no win, respins continue with a guaranteed wild until you land a winning combination.
What happens if I find a scatter during the Fun Palace Pick 'Em?
Finding a scatter symbol inside the Fun Palace instantly triggers the SET THE WORLD ON FIRE Free Spins bonus. Otherwise the Pick 'Em continues until you reveal an End Prize.
How does the Trail of Fire work during free spins?
An expanded wild moves across the reels each spin and leaves fire markers on random positions. When a wild lands on any fire position, every highlighted Trail of Fire spot turns into a wild symbol for that spin.
Can I re-trigger extra free spins in the bonus round?
Yes. Each scatter that appears during free spins adds 2 extra spins. You can earn up to 50 additional spins on top of the initial 8.
Is there a bonus buy option in Annihilator?
No, there is no bonus buy feature. You need to trigger the Fun Palace with 3 bonus dolls or land 3 scatters naturally to reach the free spins.
