Merge a Monster is a quirky puzzle and merge game set in your home lab. Drop DNA samples into a glass terrarium, combine matching ones, and evolve them into cute and bizarre hybrid creatures. Watch out for contamination goo that clogs space and disrupts merges, forcing you to manage the tank carefully. Earn powerful lab tools like the Zapper, Purifier, Catalyst, and Agitator to fight contamination and boost merges. Unlock themed tanks such as Forest, Desert, and Ocean, complete your Bestiary, and chase massive scores through clever evolution and strategic management.
