Volatile slot from Microgaming

Volatile slot from MicrogamingWe all know about volcanoes, right? That they are gaps in the earth's cortex, allowing lava, ash, and gases to leak. But what about the supervolcanoes? Most of them have a volcanic crater (caldera) that is formed 40 to 8 million years ago, during some massive rock fragments outburst. These supervolcanoes can be defined with an extreme magnitude of the eruption.

One such super hotspot is created in 2019 by Golden Rock Studio and is published on Microgaming's magma-map - the Volatile slot machine.

Technically is a 10 winways game with a 5x3 layout, built with High Volatility and a satisfactory RTP of 96.10%. There are 9 paying symbols in the paytable - high-valued: Jasmine girl, tipi tent, bonfire and jungle drums, and the usual cards A/K/Q/J/10 - on the low side of the provision table. Plus there are 2 types of Wilds, delivering big bonus eruptions and lava flows along with Multipliers. The slot offers a gigantic potential of 25 600x the total bet (according to the developer), which cannot fail to enthuse even the most critical players. The delight is full if you are one of the ethnic music fans, who could certainly appreciate the primal tribe soundtrack with an animal skin drums accentuation.

Personal testers’ opinion

  • We were set with high expectations at the beginning of our test period. Checking the following 3 pivotal game properties: Design and Gameplay, Potential and Paytable, and lastly Test results will form our final position. The slot is reasonably popular, so habitually the prize pool will be inflated, set to distribute massive prizes.
  • The Volatile online slot comes with a plainer (not piquant) design and is not endowed with revolutionary features. Yet the unpredictability of how every session evolves is keeping the suspense. Often is blazing red (volcanic) and edgy, like many other intense high variance games. The winning prospect is insane, yet the slot didn’t make it to the TOP 7 (according to our BNC site) games with the highest payout chances - our very own Wall of Fame.

  • Paytable-wise we could wish for higher rates, especially considering the low number of paylines and the missing Scatters. Also, the 2 sorts of Wilds are non-paying, which is yet another hold back to create more expensive combinations. The 9 different symbols bring between 40x and 6x the total bet for 5OAK, although the 4 high-valued ones have a ‘pity prize’ - for 2OAK as well.
  • In the base game, the machine regularly delivers A) 1 or 2 Volcanic Wilds and B) 1 or 2 exploding Wilds but in most cases, that doesn’t generate impressive wins. During tests in the first case we got wins of 2x to 10x the bet, and with the second sort Wilds (i.e. plural multipliers) - we received larger wins - in the area of 12x to 45x the total bet. So far, nothing striking to enlarge the bankroll, as there are many blank spins as well. And certainly nothing near the 25 600x the total bet promise (which can be achieved by 64x Multiplier and Jasmine girl - valued as 40x the total bet).
  • The waiting for the bonus round to be triggered is with tolerant length each time. So, no complaints in this regard. During the Free Spins, indeed more Wilds are dropping, and all of them have Multipliers attached. The exploding Wilds pay even if they don’t participate in the combo, it is just needed some combo.
  • And here comes the amazing component of this game: it estimates that it didn’t pay you enough and grants you multiple re-triggers! Yes, you read well: gratis and with no stipulations. How many developers can say: “Hey, your win in the Free Spins wasn’t good enough. So, let’s play it again!”? And then even one more time? Come on!
  • Now, do you need more convincing to try this Volatile slot? Our average win in the Free Spins amounted to 52x the total bet, but we managed one payout over 400x the total bet, which is not a doddle but is not as striking as we hoped for when we first launched the game.

Having all that shared, we leave negative advice for bonus hunters to complete the wagering conditions, as well as for playing with real credits. If despite the ungenerous paytable and the prevalent underperformance of the slot you still decide to gamble here, we recommend starting with funds for around 200-250 bets, giving you the chance to wait and play a couple of bonus rounds.

  • If you liked the gameplay of this machine, you should try other Golden Rock Studio productions like Star Gods slot (2020) and RaRaRa slot (2020). You will be astonished by the basic yet entertaining presentation and variety of interesting functions this developer’s games offer.


  • Wild 1- Volcanic - The regular volcano - not paid, but as usual replaces all other symbols. It can drop only on reels 2, 3, and 4. It also works as a Scatter.
  • Wild 2- Exploding - The regular volcano randomly transforms to this Exploding type. Also not paid, but carries different Multipliers (2x/3x/4x).
  • Wild 3- Plural Exploding - If more than 1 Exploding Wild symbol drops, their Multipliers are collectively multiplied. As the maximum number of Wilds per spin is 3, the best-case scenario implies 4x4x4=64 times Multiplier.
  • Free Spins - 3 of the regular Wilds dropped in 1 spin will trigger the bonus. It starts with an initial number of 10 Free Spins. Here a long string of Free Spins could be expected as the slot promises guaranteed re-trigger if you win less than 10x your bet.
