Annihilator — RTP, volatility and max win

Annihilator is a licensed Play'n GO slot built around the rock band of the same name, with guitars, a devil and a dark grey stage setting the scene. When a wild lands, it stretches over its whole reel and triggers a re-spin.

Visually, Annihilator sticks to black and grey, guitars and a devil figure, much like a metal album cover. Its reels sit in a 5×3 frame carrying 10 paylines, and a spin costs €0.10 at minimum and €100 at most, covering both very small and high bets. Play'n GO released Annihilator on April 23, 2020.

Payouts follow 10 paylines, fixed in place over the 5×3 grid. Matching symbols must stand in a row along any such line to pay. An expanding wild fills its reel completely, so it counts on every line that crosses that reel. The symbol swap can also change symbols on the reels into others, which opens up new combinations on the lines.

Expanding wilds and re-spins: a wild stretches over its whole reel, then the reels spin again with that wild reel in place.

Symbol swap: symbols on the grid are switched for others to complete lines.

Free spins and bonus game: scatter symbols belong to the free spins round. Besides the wild, regular symbols can also expand across their reel. Dedicated bonus icons lead to a pick game in which you choose hidden objects.

In Annihilator, both wilds and regular symbols can expand across whole reels, and more titles with that mechanic are grouped under inferno slots with expanding symbols.
