About this game

In Fish Evolution, enter the deep blue sea floor for an exciting underwater adventure! This casual puzzle game lets you create unique underwater creatures by merging and evolving fish. Begin with simple fish and combine them. You should use strategies to unlock rare species and dominate the seas! The game offers two interesting modes: Fish Evolution and Merge Aquarium. In Fish Evolution mode, starting with the first-level fish, keep eating food in the ocean to strengthen yourself, and eat fish that are lower than you. In this way, you will continue to level up and create more mysterious sea creatures. When you meet higher-level sea creatures, you can collect defensive items to prevent yourself from being eaten. Switch to Merge Aquarium mode, buy fish and cannonballs, and place them on your station, strategically positioned to defeat the armies of fish on the other side. Come to try to merge one of the most unique creatures.
