Term #8 - Don't open multiple accounts
Only one account per household, person, computer, email address, credit card number, or shared computer environment such as a library, workplace, fraternity, university or school is permitted. No winnings shall be paid if we detect multiple accounts.
Players who choose to deposit using a credit card must use a credit card under their own name. Credit cards under the name or address of anyone other than the person who opened the account will be considered "third party credit cards." Users of third party credit cards will have any winnings voided and will have all deposit(s) refunded back to the third-party card. Management may also, at its discretion, close the account of any player using third party credit card(s) to prevent suspected fraud. Any payout requests for players who used third-party credit cards will be denied.
