Each player is limited to a single account at any given time. This policy extends to dormant accounts as well. It’s against the rules to register more than one account per person, household, IP address, computer, mobile device, or credit/debit card.
If you have more than one account or try to create more than one account, you risk having all of your accounts frozen or closed. If you do so, your account may be terminated, and any accumulated winnings may be nullified.
