I take years long breaks between Tamagotchis sometimes. I actually put my pets aside a few months ago to focus on work. Tamagotchi is always waiting for you when you're ready to come back :)

Take the toy apart, clean it, let it dry, then try to put new batteries in it. Most importantly, STAY CALM!

I was thinking about this topic and was curious if you found anything about maximum lifespans? (I want to know if my Pochitchi kicked it because it was his time or if I was once again a bad owner.)
Does a real dog or cat have a pause button?
Tamagotchi is meant to be a pet, not a game, so nine times out of ten there won't be a pause function built in.
Luckily the Uni is pretty hardy!

I'm very sorry to be the one to tell you, but your 10-year-old Tamagotchi is gone. The fact that he laid an egg before departing means you gave him a nice full life! Press A & C together to hatch the egg he left you.
The Devilgotchi is a slog (takes over a week to grow into an adult, goes off randomly at night) but it's good fun. Personally my favorite classic variant! I was very lucky to pick mine up used in 2020 before the 25th Anniversary sparked a huge Tama revival over here in Japan!
On the other hand...

Also, the Angelgotchi is extremely easy to care for :) So don't feel like you have to have certain achievements before raising one!
One of these days I'd like to succeed in raising a Mametchi or Mimitchi on a classic device...I've never pulled it off.
