There are a number of features that can be triggered during the base game, for example, the Avalanche. Any winning symbols will disappear while new symbols will fall down in their place. The main feature of the game is the infamous Twin Reel Feature. At the start of each spin, the Twin Reel Feature will be active, it will show identical symbols across the reels. It can also expand to cover more reels before picking a symbol. 

There is a bonus round available as well. You will need to land 5 scatters or more to get the bonus. In return you will have 15 free spins to use, any scatters that land will add one free spin. In the bonus, the reels will be maxed out and wild multipliers will also appear. Both the Avalanche and Twin Reel feature will be active through the bonus.
