 Other than the code from the Nintendo DS Game, the passwords unlocked on the pet or on TamaTown.com will not work on any other Tamagotchi, thanks to the username system on both Tamatown and the Tamagotchi itself.There are six new games, as well as new games that the Tamagotchi play with each other when connecting.The winner gets a certain number of points depending on what stage the connecting Tamagotchis are in.
