To catch a fish the player must cast the line into the water and then use the reel in the bottom-right corner to reel in the fish.
If the player reels in the fish when it is splashing it can snap the line and the fish can get away.
Upon getting the fish on the hook two lines appear; one in the front and one in the back.
The process may involve going back and forth between reeling and stopping in order get the fish over the front line which determines if it is caught.
Likewise, if the fish makes it too far away and over the back line then it escapes and the player does not get to keep the fish.
