Can two or more people use the same computer, but different accounts to play at a casino?
There is a possibility that this will not be allowed. In order to prevent cheaters to create multiple accounts (which is not allowed) and to abuse the welcome bonus, online casinos and poker rooms will allow only one active account per computer. Every time you log in, your IP is logged, so the system will recognize if more than one account uses the same computer. You may also be blacklisted in some rare cases.
