I believe Chemistry1988's points (https://bitcointalk.org/index.php?topic=796321.msg8995312#msg8995312) and yakuza699's points (https://bitcointalk.org/index.php?topic=796321.msg9001511#msg9001511) are correct that your way of determining the bet results based on solely the transaction ID is faulty.

yakuza699 isn't lucky for getting "00", but he can make as many such transactions as he wants to.
