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!!!
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!
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.
Your Tama will have a baby if the matchmaker comes, or if it falls in love with another Tama and gets married. To get them married, both Tamas have to be of the opposite gender and you have to connect them until their friendship level is four hearts. (honey speeds up the process)
kill
you need about 40 to 50 hearts for max friendship
it goes away eventuly
Go to the television and click 'dating show' if the matchmaker shows you something, no matter how ugly it is, take the chance,. It may be a very long time until the matchmaker offers another tama. --MewMew
220 or more, it should show 2 hearts on the friendship checker.
press your stylus over the Pokemon you wanna check your friendship with one heart - ok two hearts - good two hearts that grow - excellent
no
well first of all you can choose whether you want to connect with another Tamagotchi device or go on the dating show. i recommend connecting to another Tamagotchi. well if you choose to connect to another Tamagotchi you would of have to of be pretty good friends before you marry otherwise the Tamagotchi's may refuse to marry each other. to strengthen the bond just connect to the other Tamagotchi and play a couple of games. that would probably make the friendship level high enough. hope this helps
yes two big hearts
