Black Widow contains a Super Stacks feature. At the beginning of each spin, any reels containing stacks of icons will turn into one of the main symbols in the game. This can result in pretty big wins. The bonus round is triggered by landing the green smoke symbol on the second, third and fourth reels. In the bonus round, the player will land 7 free spins which can be re-triggered to offer up to 98 free spins in total. The Black Widow icon is the wild symbol, and it can substitute itself for all other symbol in the game, with the exception of the bonus icon.
