How to Play

Catch fish

Join all the other Fishington.io players on the boardwalk to catch fresh fish like Crappies and Perch. Just cast your line out to the desired level and wait for a fish to bite the bait! 

The key to a successful catch is to tap and hold to keep the hook in the green zone. After a bit of struggling, the bar fills up and the fish is yours to sell in the fishing shop. Every fish you catch is added to the wiki, where you can view all the fish species you have caught.

Upgrade your gear

Catching and selling fish is how you earn money and level up in Fishington. Once you’ve earned enough money and reached the required level, you can buy new gear like baskets and rods in the fishing shop.
