Coin Volcano

Coin Volcano is a 3x3 slot from 3 Oaks Gaming, released in August 2023. The game uses a volcano and coin-collection theme, with the middle row playing a key role in feature triggers. In the demo version, players can play for free and practice before playing for real money.

The main game does not use standard paying symbols. Instead, the feature set centres on Sticky Coin symbols, bonus symbols, and respins. Landing three symbols on the middle row can trigger the Bonus Game, which begins with three respins and resets the counter each time a new bonus symbol appears. A Mystery Jackpot symbol may reveal Mini, Minor, or Major jackpot prizes, while a Collect symbol gathers the current coin values. Filling all nine positions can award the Grand Jackpot.

Coin Volcano also includes a Volcano Multiplier Feature, which may add one to nine multipliers during respins, and an Ultra Bonus Game that starts with a multiplier feature in place. The slot has an RTP of 95.66% and a bet range from 0.1 to 60, with jackpots displayed as Mini, Minor, Major, and Grand levels.
