When your Tamagotchi character reaches breeding age, and hasn't mated yet, the matchmaker will begin visiting. The matchmaker visiting times are 10:30 AM, 3:00 PM, and 7:00 PM. She will visit at these times for three days, begining a couple of days after your Tamagotchi becomes an adult. At each visit she will display a prospective mate your your approval. If you reject her offer, she'll go away until the next scheduled visiting time. If you accept her offer of a prospective mate, your Tamagotchi character will mate and have a baby. Instead of accepting the matchmaker's offering, you could connect with another Tamagotchi, and after a while they'll fall in love and can mate by connection.
