Merge Mystery is a free puzzle game developed by Ace Viral for Android devices. It takes you on an adventure through the mutant world, where you discover new islands inhabited with mystery mutations. Your goal is to get to the bottom of it by exploring these lands and finding out what is mutating these animals.

The game features over 30 mutants, including the Furious Panda, Fighting Dog, and Cyber Animal Fighting, which you can collect and merge to unlock legendary creatures. You can also travel through all the mutant worlds to find new artifacts and mutations for your creatures. The game also includes 25 fun bosses to discover and beat, such as the Cyber Fish, Gryphon, Wolf, and even an evil mutant tortoise.

Merge Mystery is not just a puzzle game, but also a monster battle game. You can battle your monsters and mutants against the evil mutants that are a real challenge. In addition, you can customize your creatures with a wide variety of mutations, such as sticking an axe on a dog's head or giving it octopus arms or wasp wings.

The game is optimized for tablets and can be played offline, so you do not need an internet connection. There is no grinding to unlock, and it is not pay-to-win, so you can enjoy the game without any pressure.
