About Koi Tycoon

An addictive idle merging game. Build your own Koi fish company and grow your business. Release your Koi fishes into the pond and earn money every time they cross the finish line. Buy new Koi fishes (or collect them from the gift boxes), and merge the same level Koi fishes to upgrade into a new type. The higher-level of the Koi fishes, the more money you will earn. Use your earnings to buy upgrade packages in the Shop to help you make money faster!
