How can I reset my score?
Unfortunately, there is no option to reset your score. The only way is to disconnect from Online Save in Subway Surfers and reconnect using a different Google/Game Center account. You also can’t log in to the same Facebook as you have previously used to save your High Score.
Note: this will reset ALL other progress as well. However, the progress can be restored by reconnecting to Online Save with your old Google/Game Center account.
