You shouldn't play Satoshi Dice from Silk Road, when you win the Bitcoin are sent back to the address they was sent from and obviously you don't own the address they was sent to. You'll have to contact market support and see if they're able to help you out. Market Support - Here is the link: http://silkroad6ownowfk.onion/users/support/message Support is heavily backlogged at the moment so I am unable to give you a estimation on when you'll receive a reply from them.
