Using your Tamagotchi is easy. First, turn it on with the included CR2032 battery. You'll need to regularly feed your pet to keep it happy and healthy. When it makes a mess, clean it up right away. If it starts acting up and bothering you without a need, you can discipline it. Play the Numbers game often to have a chance at getting different Adult Tamagotchis. Make sure to keep it attached to your bag or a safe place so you don't lose it. When the battery runs out, replace it with a new CR2032 battery. This Tamagotchi is for ages 8 and up, so younger kids should use it with adult supervision.
