Merge Hatchimon is an offline role-playing game that lets you hatch adorable monsters. In this game, you will meet a doctor who studies the monsters, which is called Hatchimons. He will teach you all the knowledge he acquired from studying the cute monsters and that information will help you in your adventure on the mysterious island.

Form a team of 5 Hatchimons that will come along and help you with your adventure. They can get better and stronger through gym training.

Upgrade the eggs to increase your chance of obtaining and hatching stronger Hatchimons. The Hatchimons with the same characteristics synthesize and evolve. 

There is an auto-battle feature that you can use for 10 consecutive times.
