3 Coin Volcanoes

3 Coin Volcanoes by Booongo is a 4x3 slot set around three volcanic symbols and two active lines. The game includes a bonus game, respins, and multiple jackpot levels, with MINI, MINOR, MAJOR, GRAND, and ROYAL prizes described in the pay rules. Players can use the demo version to play for free and practice before playing for real money.

In the main game, bonus symbols can trigger green, red, and blue fire effects that wake the volcanoes above the reels. This can lead to one of three boosters: LIFE, which refills the respin counter; MULTI, which adds multipliers that combine in the same cell; and GROW, which unlocks two extra rows. A Lucky Eruption feature can also activate the bonus game with at least two boosters.

During the respin round, four symbols on either active line can start three respins, with mystery symbols that can reveal jackpots or transform into other symbols. The Boost symbol collects current values, and filling the screen may award the Grand Jackpot. When GROW is active, filling the expanded grid can trigger the Royal Jackpot.
