there would be no way to make sure the numbers are different unless you set up a database.
I suggest setting up a DB with 3 fields: ID, IP, Timestamp
when they click "Play Now" have it loop to see if their IP exists, if it does assign then that ID and update the time stamp. If it doesn't create a new ID.
Does that make sense?
