Slot Features

The lava goddess Wild symbol can appear stacked on any reel, while the premium animal symbols pay between 2 and 5 times your stake for 5 of a kind winnings. Although it may not always be fully visible, the Wild will substitute for other pay symbols to assist complete and/or enhance winning combinations. The wild symbol also pays 10 times your wager for five of a type.

Every time you get a Random Reveal symbol, which appears on the screen, a randomly selected matching pay symbol from the basic game is revealed. In the regular game, it can also disclose a red, green, or purple gemstone sign. In the bonus round, it can also display a volcano symbol. 

Each time one or more revealed gem symbols are collected in their respective volcano metres above the grid, you have a chance of starting the Action BoostTM Free Spins round. What Action Boost feature, or combination of features, will be active in the bonus round depends on the triggering gem or gems.

The grid enlarges by one additional row per reel during the 5 free spins that the Green Gem triggers. For the duration of the feature, this doubles the paylines from 20 to 40. During this feature, random reveal symbols may disclose volcano cash rewards. All wilds that appear will nudge fully in place every time.

The volcanic symbols award a cash payout or a jewel symbol, while the Red Gem trigger grants you 10 free spins. For the Mini, Minor, Major, or Mega jackpots, which pay 10x, 50x, 500x, or 5,000x your wager, respectively, you need to gather 3 green, 4 blue, 5 purple, and 6 red jewel symbols.

5 free spins are awarded when the Purple Gem trigger is activated, and as volcano symbols are revealed, you can win extra free spins or cash. Each time you spin, you'll receive a random win multiplier of x2, x3, or x5.
