The Volcano eruption game is played using five reels, with 20 paylines. The Wild and Scatter symbols help to increase your chances of winning. When three or more scatter symbols land on the middle reels, you'll get the Eruption feature. The Eruption feature is triggered when you get at least three of them on the middle reels. When the erupting volcano hits, you'll win 5 times your stake as a cash prize.
There are other features that make this game stand out from other online slots. Its Wild and Scatter features are worth looking into. If you land 3 scatters on the middle reels, you'll trigger the Eruption feature, which allows you to receive up to 100 free spins. During this feature, wilds will rain down on the reels, and you'll win five times your stake. That's a pretty cool bonus!
For a better understanding of volcano eruptions, it's important to understand the structure of the Earth. The outermost layer is the lithosphere, and is composed of the upper crust and the mantle. The crust is made up of mostly silicate rock and is between 10 and 100 km thick. The mantle is the next layer of the earth and is the most dense layer. If the upper crust is erupting, the entire mantle is up to 660km deep.
