I do not live on the east coast or west coast, i am in the middle coast...lol, anyways I am not sure how you get it, I have played three times as of this moment, this afternoon, and won all three times, the first game i got high team score, the second, high team score and high individual score and this last time, I did not get high score at all and still won the buzz cup and 100 credits, so I cannot answer how they are giving them and to whom....if someone else finds out, let me know, I am on my way to play again and will report back asap....
edit to say...that the codes are working and the game is having problems, after i click here, for another window to open with code, it does but after i try to go back to the game, it closes with a problem of some sort, i checked the report for problem and it is in jibberish i do not understand, but i sent them a report anyways
