About Volcano Eruption: Extreme Slot

Volcano Eruption: Extreme is NextGen Gaming’s attempt to revisit a slot which has proven to be a success for them in the past. This release is closely linked to its predecessor, the simply titled Volcano Extreme, and so is something of a sequel if you will. Of course, the primary difference between this game and the original release is that NextGen has kitted out the Volcano Eruption: Extreme slot with a handful of nifty goodies and features which weren’t available in the first slot.


There isn’t too much unusual about the payline and reel structure in Volcano Eruption: Extreme. There are 5 reels and 25 for players to bet on, and all twenty-five of those lines are fixed into place. Players do have the option of flexing their financial muscles, though, with the slot taking on wagers which cost as little as 25p a game up to no more than £250 a spin. A medium variance release with a return to player (RTP) rate of 95.4%, this is a game which can deliver non-progressive wins worth up to 500x your stake.

Special Features

As you might expect, a wild symbol is represented by an erupting volcano. That wild can appear only on the three innermost reels. It can be used to act in the stead of any other symbol without exception, and can also be used to trigger the free spin bonus round in this game.


Players may also wish to keep an eye on the volcano which appears in the background of the slot. From time to time, it will rumble and erupt. When it does so, the volcano will freeze any winning combo which appears on the reels, and re-spin the reels which don’t play a part in that. It may also spew out wilds onto the reels to help players add to that winning combination.

Free Spins & Bonus Features

As for the proper free spin casino bonus, this round is triggered when three of the volcano wild symbols appear on the second, third and fourth reels. Alternatively, landing these symbols via the randomly triggered erupting volcano is just as good. Either way, players are treated to a total of 5 free spins.


Throughout those 5 free spins, the third reel will be transformed into an expanding wild. Once again, extra wilds may be spewed out of the volcano to provide you with easier wins. It is worth noting that the randomly triggered volcano bonus seems to occur more frequently during this bonus round than in the base game. It is just as well that this happens to be the case, as you cannot win any further free spins in this feature.


Volcano Eruption: Extreme is a more extensive take on an original NextGen Gaming slot. Any player who has tried Volcano Eruption is likely going to find this second instalment a breath of fresh air, as it significantly improves upon the gameplay of its predecessor. It can be found at all top sites which offer NextGen Gaming slots.
