If you ran across this Oddsmaker thread because you got one of those $50 checks in the mail and you're wondering if it's legit, DO NOT WASTE YOUR TIME WITH ODDSMAKER. I've deposited (and, more importantly, withdrawn) real money on most of the major sites, so I'm very familiar with how online cardrooms are run. The only problem I've ever run into was a delay (< 2 week) in cashing out. ODDSMAKER IS NOTHING BUT TROUBLE and has the most restrictive cashout rules I've ever seen.
I opened my account with the free $50 and read the fine print on cashing out; 200 raked hands, play for 60 days, $100 minimum cashout amount with a $8 administrative fee (cheapest option available), and a PIN number was required. They didn't give me a PIN number when I opened the account, but after sending several e-mails to Customer Support they finally sent it to me.
Shortly after getting the PIN number, I tried logging into the software and got a pop-up message saying "Your account was banned. Please contact management staff." I contacted them and was told the ban was due to a "hardware conflict", which was eventually explained to mean that I had used foul language or advertised on the site. Trust me, I never did either. I asked Customer Support to provide the chat log on which they based the ban because there was absolutely no way I had cursed or promoted other sites, and was told the "Network" had banned me and Oddsmaker didn't have any specifics why they had done so. I asked for an e-mail address or phone number to contact the "Network" and never received a response.
I actually got a call from Oddsmaker yesterday. Not to apologize for the ban and reinstate my account, but to offer me a fabulous 10% deposit bonus. I mentioned that it wouldn't do me much good since my account had been banned for no apparent reason, and was told they'd have it fixed within 15 minutes but recommended I open a new account as I couldn't take advantage of this wonderful deposit bonus and the free $50 at the same time. I'm sure if I were stupid enough to do so, they'd say I violated Terms and Conditions by having multiple accounts and freeze my funds. Oh... and 24 hours later, my original account is still banned.
In summary, DO NOT UNDER ANY CIRCUMSTANCES OPEN AN ACCOUNT WITH ODDSMAKER. It is by far the worst online cardroom I've played on.
