In The Dog House Multihold, Wild symbols appear on reels 2, 3, and 4 and substitute for all other symbols except the Scatter. During the base game, they act as regular Wild symbols. However, during the free spins bonus, any Wild symbols that land become sticky and remain in place for the duration of the bonus round. Additionally, when a new grid is unlocked, any sticky Wilds from the previous grid(s) are copied onto the new grid in their respective positions, increasing the potential for more winning combinations.
