Devil's Number Bonus Features

Mark of the Beast

Devil's Number features two primary bonus features named Mark of the Beast. The first can affect lower-value symbols. If you can make a full line of any lower-value symbol, the Mark of the Beast may trigger randomly and remove these symbols, causing a cascade. A cascade is where symbols get removed from the play table, and new ones fall in their place, allowing for more combinations in one spin.

The second Mark of the Beast only affects higher-value symbols. If you land a line of any higher-value symbol, the Mark of the Beast may appear, and the symbol involved may get upgraded so that it is worth more during that spin.

Devil's Number Free Spins

Landing three 9 symbols will trigger the Free Spins bonus round. You are provided 12 free spins for this bonus feature. Furthermore, both bonus features are active and permanent in this round. Triggering the higher value Mark of the Beast feature means the upgraded symbol stays upgraded permanently throughout the bonus round; if a lower value symbol gets removed from the play table, it's gone until the round's end.
