The article stated the following;
"After 4:00 pm on August31, 2014, any person holding Showboat Casino SLOT VOUCHERS may redeem those items at Caesars of Harrah's Resort for up to 12 months from the date of issuance". I did not read a deadline for Showboat chips or tokens to be redeemed at Bally's, Harrah's, or Caesars.
