3 Oaks Gaming expands Hold & Win series with Coin Volcano 2 launch

iGaming content distributor 3 Oaks Gaming has released Coin Volcano 2, a sequel to its popular Hold & Win slot series. The new game expands the classic 3x3 layout to a 3x5 grid, increasing win potential and action.

Building on the success of its predecessor, Coin Volcano 2 offers players access to Bonus Games by landing three symbols on a single payline. Coins remain central, with Bonus tokens offering fixed jackpots from Mini to Major.

New symbols—including Mystery Signs and Mystery Jackpot Symbols—reveal their hidden values when triggered, while the Coin Collector icon collects all visible coins for an instant payout.

The game also introduces the Ultra Bonus Game, which can trigger at random. This feature guarantees Volcano Multipliers of up to 9x on the reels, with values stacking when multiple multipliers land in the same position.

For players seeking higher rewards, the Boost Bonus Game is now available through the Buy Bonus option in select regions. This feature starts with a guaranteed 5x Volcano Multiplier.

"In Coin Volcano 2, we have built upon the classic 3x3 slot format and introduced a new bonus feature to deliver a high-energy, rewarding Hold & Win experience,” said Yuriy Muratov, Chief Commercial Officer at 3 Oaks Gaming. "It mirrors our commitment to delivering exciting gameplay that players worldwide can enjoy."
