This slot by IGT has a 96% RTP, medium to high volatility, and 20 paylines. It is exciting when volcano symbols erupt and result in large payouts. You can win four jackpots, and at the top of the screen you will see the values for their payouts.

Where to play

You can play this slot and many others for real money at Parx Casino Michigan. If you sign up and make a deposit, you can use the welcome bonus you receive to try out the game. The bet range is from $0.20 to $100, and the max win is 5,000x your stake.

Symbols

You will see familiar symbols from classic slots such as fruits and bells, and other common higher-paying symbols like blue and red sevens. The Aztec fire goddess wild symbol stands in for all other symbols except the fireball and volcano symbols. She can expand to fill the entire reel with the potential for more wins. The scatter symbol is a volcano with the words ‘free spin’ on it.

Free spins bonus

When you land three volcano scatters on reels 2, 3 and 4, you activate the Free Spins Bonus. In this phase, you will see expanded volcano symbols, which increase the potential for winning combinations. Any other volcanoes that land within the expanded volcano add three more free spins, and this goes up to a maximum of 15 free spins. A Mega Fireball can activate the Hold & Respin feature from inside the free spin bonus round.

Fireball bonus

Land six or more fireball symbols, and you will activate this round where each fireball comes with its own prize. The fireballs lock in place, and the remaining positions spin independently. You start with three respins, and each new fireball you land resets the spin counter to three. You continue until you run out of free spins, or you fill all reel positions with fireballs. While filling up the grid, you will collect cash values and jackpot symbols.

Jackpots

Among the various casino categories, a jackpot slot can be one of the most rewarding with potential for large payouts. In this slot, four jackpots are available during the Hold & Respin feature – mini, minor, major and grand jackpots. Filling all reel positions in the Fireball Bonus round will award you with the Grand Jackpot that pays out $10,000.

Gamble option

When looking at how probability works in real life, it basically describes the randomness of a coin flip, which is what you will find in the ‘double or nothing’ gamble in this slot. The feature allows you to double your winnings by guessing the color of a concealed card.
