Using your Tamagotchi is easy. First, make sure the CR2032 battery is properly installed. Then, start taking care of your digital pet. Feed it regularly to keep it happy and healthy. Clean up after it when it makes a mess. If it bothers you when it doesn't need you, don't be afraid to discipline it a bit. You can also play the Numbers game for fun and to influence which Adult Tamagotchi you'll get. Always keep the Tamagotchi attached to your bag so you don't lose it. When not in use, store it in a dry and cool place. And remember, the better you take care of it, the more rewarding your experience will be.
