The game consists of interacting with Tamagotchi characters. To talk to the Tamagotchis, players are required to use a Data Carddass card, known as "Character Cards." These character cards contain different characters the player can interact with.
Players talk to Tamagotchis through the phone attached to the game. There are also a variety of conversations depending on the card scanned. So a variety of different character cards have different dialogues and themes. During conversation, players may be presented with multiple choice responses they can say to the conversing Tamagotchi. On the left side of the screen, is the relationship meter. It rises or lowers based on decisions the player makes. Also, players may bring up a second Tamagotchi character by scanning another character card, which may expand and vary the conversation.
There are also a variety of minigames which can be played by hanging up the phone or through certain sequences during conversation.
