If you mean hearts as in, health and happiness, just feed it meals and snacks.
If you mean hearts between different Tamagotchi's so you can get them married, you can't actually get the two Tama's to have hearts until there adults. But just keep conecting the two tamagotchi's together, and soon enough you'll have hearts!
kill
it goes away eventuly
you have to make them get married. to make them get married you have to make them meet a lot until you get four hearts.
In v4,when u get 3 hearts u will get a pesent from the king,usually a ring or bouqet.
Once your tamagotchi is an adult, it will breed with another tamagotchi the opposite gender, or use the matchmaker to find a partner. Then it will have a baby, and when you are raising it, and check the parent and history stats, there will be the parent's names! Believe me, I have bred heaps of V3/V4 babies. Sorry, I don't have a lot of V5+ experience :(
To Marry you need 4 love hearts{I recommend you use love potions}and keep on doing present, then eventually your tamas will marry! Hope this Helps!!!
The Tamagotchi V3 is the oldest version of Tamagotchi. You need the V5 version of Tamagotchi.
The way you get rid of ur love potion is to simply wait for the two hearts to keep blinking. However, after that the love potion will be gone.
a female tamagotchi marries with a male tamagotchi and the female tamagotchi will have a large belly . and if the female tamagotchi cant hold more longer than it will give birth.
You actually can't. But I do know that if you have a v3, you can get in without a tamagotchi.
Yes you can get mail, and get things like money from the king, robbers, snakes, poop, and hearts. The star is points you earn. And the exclamation mark is for important events.
