There are two variations of the Horseshoe Winners Circle copyright 2005 that were used at the Tunica, Bossier and Hammond casinos. These are the cards that have the Harrah's casinos listed on the back with the Total Rewards logo, etc. On one variation the last line on the back starts with "MO or IA 1-888-BETSOFF..." while the second variation starts with "MO 1-888-BETSOFF...". All three levels (Gold, Platinum and Diamond) were listed for the first variation but we only had the Gold and Diamond levels listed for the second variation UNTIL NOW! I finally discovered a Platinum card with the second variation reverse that I just added to the guides.
