Not sure how OP asking for back fund. If sent fund to their address means it will not return if you lost. It wasn't like something deposit system, by sending fund you had participated to the game. Most likely you lost your fund on gambling. Because, I have notice they required standard wallet where you have controls of your address. They will send back wining odds to from where you sent fund if in case win.
Remember to do this only from wallets that let you receive coins from the address you sent them from (standard wallet, or blockchain.info wallet, both work great - if unsure about your wallet, test with a tiny amount and if you never get a payment back, then your wallet is incompatible).
So there is no chance to get back your fund since I believe you lost it on gambling. Another thing is, odds didn't backed to sent address.
