About the Game

In this prologue, you step into Monster Lab Simulator: Prologue – experience the first steps of becoming the ultimate monster creator and battle master!

Discover the thrill of synthesizing mysterious essences, hatching rare eggs, and expanding your lab in this limited free version.

Buy mysterious essences to hatch unique Fulus from fragile eggs. Every experiment is a chance to create something new.

Discover hidden recipes by combining different essences. Unlock surprise creatures and expand your growing collection.

Enter turn-based battles in the station. Compete in tournaments for big rewards or test your team in free matches.

Orb your creatures to keep them forever in your permanent collection. Store their stats and create powerful combinations.

Sell your stored orbs for profit and invest in powerful new machines. Expand your lab, speed up production, and unlock stronger creations.

Combine three Fulus into one evolved form with the merge machine. Unlock stronger abilities, higher essence yield, and powerful new battle options.

Keep your playful Fulus out of trouble, look after them when they get mischievous, and make sure your lab stays a place where creatures feel happy and healthy.

Monster Lab Simulator delivers the thrill of synthesis and battle, the joy of collection, and the magic of uncovering the unknown all inside your very own monster lab.
