Update a score already submitted to Game Center

Question

Right now I am working on a Black Jack game for iOS and would like to have a leader board that shows which players currently have the most \"money\". So if they get a high score

Answer 1

Sorry to disappoint you but Game Center only writes a new score if it is higher than the previous one. You can reset the score board via iTunes Connect, but that will lose all previous users info.See the comments link
