How the Game Plays

Coin Volcano by 3 Oaks Gaming is an unorthodox 3x3 slot set against a fiery volcanic backdrop. Eschewing traditional paytables, it features no regular symbols, focusing entirely on a variety of bonus coins and special tokens. Winning is centered on the middle row, which acts as the game's single payline; landing any three symbols across this central line triggers the main bonus action. The atmosphere is intense, with glowing lava and rhythmic percussion that builds as the volcano prepares to erupt with prizes.

Hold and Win Bonus Explained

The core of the experience is the Hold and Win feature, activated by filling the center row. Players start with three respins, and any new coin that lands sticks to the grid, resetting the counter. These coins carry values from 1x to 4x, but the real potential lies in the special icons. Sticky Coins can appear during the base game, locking in place to help trigger the round and carrying their values into the bonus. Mystery symbols add an element of surprise by transforming into other icons at the end of the round, while the Mystery Jackpot symbol specifically targets the game's fixed prize tiers.

Volcano Multipliers and Jackpots Explained

During any bonus round, the volcano to the left of the reels can erupt, launching Volcano Multipliers onto random cells. These multipliers combine if they hit the same spot, significantly boosting the values of the coins resting there. The Coin Collect symbol is another powerful asset, instantly gathering all visible values into a single payout. For the ultimate prize, filling all nine positions on the grid awards the Grand Jackpot, contributing to a total potential win of up to 2,906x the bet.
