There's a lot of files in the-C:\Users\%Username%\AppData\Local\Google\Chrome\User Data\Default
Could you tell me which one do I backup?
No idea, sorry. That's why I said you most likely have to backup and restore your entire browser profile. Short of asking the tech support at Google, I'm not sure where you can get a better answer.
I try hard and find it , thank you!
Backup the "Local Storage".
It's the game saves.
C:\Users\%USERNAME%\AppData\Local\Google\Chrome\User Data\Default\Local Storage
