First off 48 hours after your tama has turned adult you will start to get visits from the matchmaker. Not sure of the times but your tama will beep when she arrives. Press the B button and at her side will be a tamgotchi and then it will say "love?" With the options of Yes or no. If you click yes you will be paired with that tama and then get a baby. If you select no nothing will happen and she will go away. Be careful though, if your tamagotchi gets to old they will change into an oldtimer.(the Matchmaker) Its better to choose the yes button if you want to carry on you generation.
