How to Fish frames its fishing as a recovery mission: after drinking and boating, the player crashes onto a small island and must learn to fish to make their way home. The setup gives the activity a practical purpose, while the physics-based simulation sets the tone for an experience that is not simply about catching fish.
Fishing feeds into a rough-edged progression loop. Players begin without gear or weapons, catch and sell fish, then use their earnings to buy better equipment. Quests and boss fights lead onward to new islands, where more dangerous creatures and improved gear await. There are also optional pursuits, including collecting rare fish variants, landing trick shots for extra money, and gambling for further earnings.
The store description lists support for one to four players and identifies the game as both single-player and multiplayer, with online co-op among its features. A count captures activity at a particular moment, but the listed formats provide context for the kinds of sessions that activity may represent.
