3 Oaks Gaming brings volcanic energy to the Hold and Win format with Coin Volcano, a compact 3×3 slot featuring coin values, respins, multiplier events and four jackpot levels.
The game is set against an active volcano surrounded by flowing lava and dark rock. Eruptions are more than a visual detail, as they introduce the Volcano Multiplier Feature during the main bonus round.
Coin Volcano uses a single active line across the middle of the grid. Landing three qualifying symbols activates the Bonus Game and awards three respins. New Bonus Coins remain locked in position, gradually filling the nine available cells.
A Sticky Coin can appear during the base game and remain on the reels until the feature begins. This creates visible progress before the Hold and Win round has been activated.
During the bonus, volcanic eruptions may place multiplier symbols across the grid. Between one and nine multiplier positions can appear, affecting the coin values displayed in the corresponding cells.
The Ultra Bonus Game provides an enhanced version of the feature by guaranteeing a Volcano Multiplier event at the beginning of the round.
Other special symbols include Mystery and Collect Symbols. Mystery Symbols reveal additional outcomes, while the Collect Symbol gathers the values shown by the Bonus Coins currently on the grid.
Mini, Minor and Major Jackpot Symbols may also appear during the respins. Completing all nine grid positions can award the Grand Jackpot, valued at up to 500× the total bet.
Coin Volcano keeps its main mechanics within one compact reel set. Locked coins, empty cells, multipliers and jackpot symbols remain visible throughout the feature, allowing the progress of the bonus to be followed directly from the grid.
With its volcanic presentation, two bonus modes and full-screen jackpot objective, Coin Volcano offers a focused addition to the 3 Oaks Gaming slot portfolio.
