3 Super Volcanoes Slot Review
Instead of traditional paylines and symbols, every position can contribute something special to the feature, while three colourful Volcano Boosters provide extra spins, persistent multipliers, and an expanded grid.
The ultimate objective is to activate the Grow booster and fill all 20 positions on the enlarged grid. Doing so awards the ultimate Jackpot, worth 2,000x the bet.
Special Symbols
Every reel symbol has a function. The selection includes Bonus, Sticky Bonus, Jackpot Bonus, Mystic, Mystic Jackpot, and Collector symbols. Although values and jackpots may display during the base game, they are awarded only in the Bonus Game.
Landing any four symbols across the middle row triggers the feature. However, the coloured markers attached to those symbols determine which boosters will be active when the bonus begins.
Three Volcano Boosters
Green, red, and blue markers fly into their matching volcanoes, activating the Extra, Multi, and Grow boosters respectively. The Bonus Game always starts with at least one booster, although two or all three may be active together.
The Extra booster increases the starting number of bonus spins from three to four. That extra attempt can be valuable because every newly landed symbol resets the remaining spin counter.
The Multi booster places multipliers ranging from 2x to 12x on random reel positions. These modifiers remain fixed until the round ends. Once the bonus is complete, every multiplier is applied to the symbol value or jackpot occupying its position.
The Grow booster expands the playing area from 4×3 to 4×5 by adding two rows. It creates space for more symbols and makes the 2,000x Jackpot available. To claim it, players must fill all 20 positions on the expanded grid.
Bonus Game
The Bonus Game begins with three spins, or four when Extra is active. Every new symbol locks onto the reels and resets the counter, while all previously collected symbols remain in place until the feature ends.
Boosters that were not active initially may still join the action. Coloured markers can continue to appear on symbols during the feature, potentially activating additional volcanoes as the grid fills. This means a modest opening setup can develop into a round featuring extra spins, multipliers, and the expanded 4×5 grid.
Bonus Buy
The Bonus Buy option gives you immediate entry to the feature. Players can purchase a version beginning with one, two, or all three boosters, with the cost increasing alongside the strength of the chosen setup. Availability depends on local regulations.
Verdict
3 Super Volcanoes takes the familiar collect-and-respin format and gives it a clear sense of progression. Extra extends the round, Multi raises the value of individual positions, and Grow provides more room while unlocking the biggest Jackpot.
I played the slot with demo money. I got many small wins. After a while, I triggered the bonus game but didn’t win a Jackpot. After all, playing was fun.
I particularly like that additional boosters can activate during the feature rather than being decided entirely at the beginning. With unusual special symbols, persistent multipliers, and a grid that can grow to 20 positions, this fiery slot keeps its biggest eruptions for the Bonus Game.
