catfish is a single-player fishing adventure about collecting, building, and growing stronger. Gather rewards at the lake, follow branching paths in search of treasure, raise pets, and strengthen deities. Put your builds to work in strategy battles and card battles.

You awaken in the body of a traveling cat on Cat Planet, sealed by nine Demon Kings. Your journey begins with a fishing rod at the lakeside.

Aim for a rarity. Build a Combo.
Click for a quick catch, or hold at the lake center to charge and aim for a rarity range. Catch the same rarity in succession to build a Combo, then collect bonus rewards when the chain ends. Reel in enchanted fish and gather resources for your next adventure.

Choose a path—and see what finds you
Explore branching routes and choose between treasure, trade, upgrades, and battles. Chests, the black market, contracts with the Seven Sins, and unexpected encounters give you new reasons to weigh the risks against the rewards.

Recruit mages to face the Demon Kings
Turn rare-or-higher enchantments into Catseye Stones to equip your mages. This consumes the enchantment. Arrange your units and they fight automatically; spend Core Energy on reinforcements during combat. Defend your side and break through the formations of the nine Demon Kings sealing Cat Planet.

Build a deck for Supreme Joker
Once you unlock Supreme Joker, build a deck from the deities you have collected. Combine poker hands, community cards, and Combo Skills into damage, with heroes, pets, and deity effects adding to your strategy. Win a battle, improve your build at the shop, and prepare for the next boss. A defeat ends the run.

Raise a companion. Enter the arena.
Pets have their own stats and personalities. Reshape and evolve them, then unlock active skills and ultimate abilities. Bring a trained pet into a six-way elimination tournament against five AI opponents, where drafts, equipment, and skill choices shape your final ranking.

Collect deities and refine enchantments
Fish up deity souls, then use blueprints and materials to craft deities for your Supreme Joker deck. Strengthen the deities you collect, upgrade duplicate enchantments, and refine high-level enchantments for additional effects.

Plan the next harvest
Plant, water, and fertilize crops on the farm. In the Star-Tide Workshop, buy, place, and connect machines to get a production line making special fish. There is something to tend and tinker with between battles, too.
