Praise and Time-outs
Praise your Tamagotchi when it follows your instructions and enforce time-outs when it's disobedient. Frequent praise and time-outs will earn training bars, which help the Tamagotchi grow.
Feeding and Exercise
Healthy Tamagotchis are raised by feeding them good food and exercising regularly. Feed the Tamagotchi training bars and give snacks when it needs a happiness boost. Make sure to follow up snacks with exercise to raise a physically healthy Tamagotchi.
Socializing
Find friends who have their own Tamagotchi Connection V3. Making playmates for your Tamagotchi increases its happiness and can even result in the birth of new Tamagotchis.
