Frontier's heart is a five-axis slot with three rows and twenty fixed paylines; those reels rotate within the limits of a wooden signboard hanging in front of a dusty street, one side of the salon, and the other One side is the hotel.

Sheriffs and robber symbols come in handy here, and when they land alone, they expand to fill the entire reel and act as a wild symbol; then they will move to the right (Sheriff) or leave (Robber) Until they fall off the reel.
