I recently had a $40 free play offer from Horseshoe Baltimore. I went there, put my card in a slot machine, and naively assumed it would recognize me (and my offer), just as it normally says, "Hi <name>!" But instead, I had to enter a four digit PIN. So I figured I must have set one up at some point, so I tried the ones I usually pick for myself (ATM PIN, etc.). No dice. Do any of you know what I need to do in order to create a PIN and take advantage of my free play? Sorry if that's a dumb question, but for all the years I've been in TR, I've usually just had free rooms and buffets, so no PIN needed.
