Yup!
Here's a big tip:
The first time you connect with a different Tamagotchi it is most likely to frown. Keep on connecting and you'll notice that it'll smile. That means that you got 2smileys or more. When that Tamagotchi comes over to the others' house, and when it mouths the present, and if it smiles, yours like that Tamagotchi 3smileys or more. And if the same thing happens again but if there's a herat between them, They like each other as best friends or partners.
