The fishing game genre on Steam has a new, unexpected heavyweight in How to Fish, a title that has quickly surged in popularity since its August 20 launch. The game has attracted over 127,000 players, with a peak of over 370,000 within 24 hours, and boasts an overwhelmingly positive user review score. Its rapid ascent saw it sell more than a million copies in its first two days of availability. Players have embraced it as the latest "friendslop" hit, a designation for games that offer chaotic, enjoyable multiplayer experiences perfect for playing with friends.

Despite its premise of learning how to fish, the actual gameplay deviates sharply from typical simulation. Players begin stranded on a small island with only basic supplies and an NPC who trades items for caught fish. The initial goal involves acquiring a crab fishing rod and bait to catch a giant Spider Crab that has been menacing the island's sole inhabitant. However, the game's interpretation of "fishing" quickly escalates to combat. Creatures pulled from the water are aggressive, requiring players to abandon their rods and engage in direct confrontation.

The combat mechanics involve equipping various melee weapons, such as brass knuckles and knives, purchased with in-game currency earned from catching fish and clams. For instance, a beer can for bait costs $12, while a knife is $45. Clams sell for $1, crabs for $2, and rare shrimp for $4. Success in defeating these creatures allows players to progress, unlock new equipment, and eventually access firearms for more ranged combat. The game also incorporates "trick shots" and other advanced maneuvers for bonus currency, and later introduces gambling elements.

While playable solo, How to Fish appears designed for cooperative play, encouraging groups of friends to tackle challenges together. Unlike many "friendslop" titles that offer endless replayability, How to Fish presents a more contained campaign that can reportedly be completed in a few hours. This shorter format, combined with its budget price of $8 (currently discounted from $4.95 for a limited time), has been highlighted by players as a significant draw, contributing to its widespread appeal.
