3 Super Volcanoes — slot review and demo

Mechanics and bonus game with three boosters

In 3 Super Volcanoes there are no regular symbols: only special ones land on the reels — Bonus, Sticky Bonus, Jackpot Bonus, Mystic, Mystic Jackpot and Collector. In the base game, four symbols of any type on the centre line trigger the bonus round. Wins are only awarded in the bonus game.

The key feature is coloured markers (green, red, blue) that fly to the corresponding volcanoes and activate three boosters:

• Extra — increases the number of spins in the bonus game from 3 to 4;
• Multi — adds multipliers from ×2 to ×12 to random reel positions; they remain until the end of the round and apply to all wins on their positions;
• Grow — expands the grid from 4×3 to 4×5, adding two rows and unlocking access to the ULTIMATE jackpot.

The bonus game always starts with at least one active booster, and markers on symbols during the round can switch on the others. Each new symbol resets the spin counter. All symbols remain on the reels until the end of the game. If, with Grow active, you fill the entire 20-symbol field, the ULTIMATE jackpot of ×2000 the bet drops. The Bonus Buy feature allows you to purchase entry to the bonus game with one, two or all three boosters.

Volcanic theme and high tension

The slot is built around the image of three colossal volcanoes ready to erupt. Every spin leads to the main event — the bonus game, where molten markers and boosters turn the reels into the epicentre of wins. An atmosphere of heat and anticipation of a big explosion pervades the entire gameplay.

96.03% RTP and above-average volatility

RTP is 96.03% — a level slightly above the industry standard. Above-average volatility means wins come less often but can be larger; the slot requires patience and a bankroll reserve. Maximum win reaches €372,780. You can check payout details and the bet range in the game rules (paytable) at the operator.
