Developer Coin Volcano 2 by 3 Oaks Gaming is a 3-reel slot released in August 2025 with a 3x5 layout and three paylines. The game centres on volcano-themed mechanics, including Volcano Multipliers and a Boost Bonus Game, while fixed jackpots can appear during play. The bet range runs from 0.1 to 100.
In the bonus game, filling the middle row with symbols triggers three respins. A Sticky Coin can remain on the reels until the bonus is activated. During respins, Coin Bonus Symbols may land with different values, including Mini, Minor and Major jackpots. A Mystery Jackpot Symbol can reveal a jackpot prize, a Mystery Symbol may turn into a Bonus or Jackpot Symbol, and a Collect Symbol gathers current symbol values. Filling all reel positions can award the Grand Jackpot.
The demo version is available for players who want to play for free and practice before playing for real money. It also allows a closer look at the Volcano Multiplier feature, which can add up to nine multipliers to the reels, as well as the Ultra Bonus Game and the Boost Bonus Game, where multipliers start at x5 in eligible regions.
