Gameplay

How Harpoon a Fish works

In Harpoon a Fish you aim at a target and fire your harpoon, then time your reels to pull the fish in. Caught fish can be placed in your aquarium, where they help you grow a new pet.

The goal is to fill your index with fish and find the biggest and rarest sea monsters. You do this by getting fat and sinking deeper to discover new creatures, and by evolving the fish you already have.

The game stands out because you can also steal from other players by harpooning their fish and testing your skill against them.
