Pausing it each night for a week should still add up for at least a day. I can only guess you've been pausing it like crazy. When your Tamagotchi is paused, it doesn't grow, so the age won't go up.
Well, your Tamagotchi only grows when it's sleeping or when it's off pause. If you want it to grow I would suggest putting it to sleep every night and then it should start growing. Hope this helps
It's not the battery either cause it's a new battery.
Mah sisters ish still 0 (shes having the same prob as yeh) except shes getting everything an adult can get like the games and stuff?
maybe it's a glitch......did yeh try to debug yer tama??
Cause I did that with both of ours but I only took the screws out then decieded not to do it put the screws back in and ever since then they have been weird? idk....
did you play with it only when you went to check on it or play a game and the rest of the time keep it on pause? that could be the case. keep it on pause only when you can't check up on it exept at night.
