"Adopt Me!" is about adopting and taking care of different animals. Pets are grouped into 5 classes, based around how common they are and how much you have to pay for it. These groups are common, uncommon, rare, ultra-rare and legendary. Pets grow up from junior to adult. If a player has four adult pets of the same type, they can create a "neon" pet, and four neon pets can be combined into a "Mega-Neon" pet. Purchases can be made with the money of Roblox, robux, and through Adopt Me!'s own currency, Bucks. Bucks can be earned by feeding and taking care of your pet.
