The Tamagotchi iOS app My Tamagotchi Forever has updated to version 3.10. This brings the ability to watch fireworks for rewards.
There are actually two firework shows to watch, a larger one to the left of your house in Tamatown which awards diamonds and a smaller one to the right which awards coins. The larger display, seen in the screenshot above, requires an active subscription or watching an ad to access once a day.
Let us know what you think and feel free to share your Tamagotchi screenshots below!
