Coin Volcano 2

Booongo's Coin Volcano 2 is a video slot featuring a Hold & Win mechanic, set on a 3×5 grid with a total of 15 positions. Unlike traditional slots, it does not have paylines or line wins, and the base game only pays out through its bonus features. To activate the main Bonus Game, players must land three bonus symbols on the middle row, which initiates three re-spins, resetting to three each time a new bonus symbol appears.

In the base game, Sticky Coin symbols can show up, holding values between 5× and 9× the bet, and they remain locked until a bonus round is activated, at which point they pay out. During the bonus rounds, players will encounter coin symbols with lower values (approximately 0.5×-4× the bet) as well as fixed jackpots labeled Mini, Minor, and Major. Additionally, there are Mystery Symbols that can reveal other bonus or jackpot symbols at the end, along with a Coin Collect symbol that accumulates all current coin and jackpot values when it appears, remaining in place until the bonus concludes.

The Volcano Multipliers feature may randomly activate during bonus rounds, adding +1 multiplier to random cells, and allowing multiple multipliers to stack on the same cell, enhancing its value when prizes are awarded. A more potent version of the Bonus Game is the Ultra Bonus Game, which can trigger randomly and starts with Volcano Multipliers already in play, offering greater chances for additional multiplier eruptions.

If the option is available in your lobby, players can utilize a Bonus Buy feature to directly enter the Bonus Game, the Ultra Bonus Game, or a Boost Bonus Game that features enhanced multiplier values. Achieving a full grid of 15 positions during a bonus or Ultra Bonus round will grant the Grand Jackpot, with a maximum win capped at 500× the stake.

You can play it for real money.
