You have been paying attention to inserts haven't you??
The pictured rack of chips represent 32 different Las Vegas Casinos. The person to correctly identify the most casinos before 12:00 Midnight tonight EASTERN time will receive the two Harrah's items pictured below the rack. These are N6167 and N6161.
If more than one person identifies them all (or the same number of correct guesses) the earliest response will win.
Good luck and have fun.
